Subject: Books and articles about Neural Networks?

Most books in print can be ordered online from http://www.amazon.com/. Amazon's prices and search engine are good and their service is excellent.

Barnes & Noble http://www.bn.com/ seems to have a slightly larger stock of technical books than Amazon, but their search engine is inferior and their web response is slower. It's a good idea to check both Barnes & Noble and Amazon for availability and prices.

Bookpool at http://www.bookpool.com/ does not have as large a selection as Amazon or Barnes and Noble but they often offer exceptional discounts.

The neural networks reading group at the University of Illinois at Urbana-Champaign, the Artifical Neural Networks and Computational Brain Theory (ANNCBT) forum, has compiled a large number of book and paper reviews at http://anncbt.ai.uiuc.edu/, with an emphasis more on cognitive science rather than practical applications of NNs.

The Best

The best of the best

Bishop (1995) is clearly the single best book on artificial NNs. This book excels in organization and choice of material, and is a close runner-up to Ripley (1996) for accuracy. If you are new to the field, read it from cover to cover. If you have lots of experience with NNs, it's an excellent reference. If you don't know calculus, take a class. I hope a second edition comes out soon! For more information, see The best intermediate textbooks on NNs below.

If you have questions on feedforward nets that aren't answered by Bishop, try Masters (1993) or Reed and Marks (1999) for practical issues or Ripley (1996) for theortical issues, all of which are reviewed below.

The best popular introduction to NNs

The best introductory book for business executives

Bigus, J.P. (1996), Data Mining with Neural Networks: Solving Business Problems--from Application Development to Decision Support, NY: McGraw-Hill, ISBN 0-07-005779-6, xvii+221 pages.
The stereotypical business executive (SBE) does not want to know how or why NNs work--he (SBEs are usually male) just wants to make money. The SBE may know what an average or percentage is, but he is deathly afraid of "statistics". He understands profit and loss but does not want to waste his time learning things involving complicated math, such as high-school algebra. For further information on the SBE, see the "Dilbert" comic strip.

Bigus has written an excellent introduction to NNs for the SBE. Bigus says (p. xv), "For business executives, managers, or computer professionals, this book provides a thorough introduction to neural network technology and the issues related to its application without getting bogged down in complex math or needless details. The reader will be able to identify common business problems that are amenable to the neural netwrk approach and will be sensitized to the issues that can affect successful completion of such applications." Bigus succeeds in explaining NNs at a practical, intuitive, and necessarily shallow level without formulas--just what the SBE needs. This book is far better than Caudill and Butler (1990), a popular but disastrous attempt to explain NNs without formulas.

Chapter 1 introduces data mining and data warehousing, and sketches some applications thereof. Chapter 2 is the semi-obligatory philosophico-historical discussion of AI and NNs and is well-written, although the SBE in a hurry may want to skip it. Chapter 3 is a very useful discussion of data preparation. Chapter 4 describes a variety of NNs and what they are good for. Chapter 5 goes into practical issues of training and testing NNs. Chapters 6 and 7 explain how to use the results from NNs. Chapter 8 discusses intelligent agents. Chapters 9 through 12 contain case histories of NN applications, including market segmentation, real-estate pricing, customer ranking, and sales forecasting.

Bigus provides generally sound advice. He briefly discusses overfitting and overtraining without going into much detail, although I think his advice on p. 57 to have at least two training cases for each connection is somewhat lenient, even for noise-free data. I do not understand his claim on pp. 73 and 170 that RBF networks have advantages over backprop networks for nonstationary inputs--perhaps he is using the word "nonstationary" in a sense different from the statistical meaning of the term. There are other things in the book that I would quibble with, but I did not find any of the flagrant errors that are common in other books on NN applications such as Swingler (1996).

The one serious drawback of this book is that it is more than one page long and may therefore tax the attention span of the SBE. But any SBE who succeeds in reading the entire book should learn enough to be able to hire a good NN expert to do the real work.

The best elementary textbooks on practical use of NNs

Smith, M. (1993). Neural Networks for Statistical Modeling, NY: Van Nostrand Reinhold.
Book Webpage (Publisher): http://www.thompson.com/
Additional Information: seems to be out of print.
Smith is not a statistician, but he has made an impressive effort to convey statistical fundamentals applied to neural networks. The book has entire brief chapters on overfitting and validation (early stopping and split-sample sample validation, which he incorrectly calls cross-validation), putting it a rung above most other introductions to NNs. There are also brief chapters on data preparation and diagnostic plots, topics usually ignored in elementary NN books. Only feedforward nets are covered in any detail.

Weiss, S.M. and Kulikowski, C.A. (1991), Computer Systems That Learn, Morgan Kaufmann. ISBN 1 55860 065 5.
Author's Webpage: Kulikowski: http://ruccs.rutgers.edu/faculty/kulikowski.html
Book Webpage (Publisher): http://www.mkp.com/books_catalog/1-55860-065-5.asp
Additional Information: Information of Weiss, S.M. are not available.
Briefly covers at a very elementary level feedforward nets, linear and nearest-neighbor discriminant analysis, trees, and expert sytems, emphasizing practical applications. For a book at this level, it has an unusually good chapter on estimating generalization error, including bootstrapping.

Reed, R.D., and Marks, R.J, II (1999), Neural Smithing: Supervised Learning in Feedforward Artificial Neural Networks, Cambridge, MA: The MIT Press, ISBN 0-262-18190-8.
Author's Webpage: Marks: http://cialab.ee.washington.edu/Marks.html
Book Webpage (Publisher): http://mitpress.mit.edu/book-home.tcl?isbn=0262181908
After you have read Smith (1993) or Weiss and Kulikowski (1991), consult Reed and Marks for practical details on training MLPs (other types of neural nets such as RBF networks are barely even mentioned). They provide extensive coverage of backprop and its variants, and they also survey conventional optimization algorithms. Their coverage of initialization methods, constructive networks, pruning, and regularization methods is unusually thorough. Unlike the vast majority of books on neural nets, this one has lots of really informative graphs. The chapter on generalization assessment is slightly weak, which is why you should read Smith (1993) or Weiss and Kulikowski (1991) first. Also, there is little information on data preparation, for which Smith (1993) and Masters (1993; see below) should be consulted. There is some elementary calculus, but not enough that it should scare off anybody. Many second-rate books treat neural nets as mysterious black boxes, but Reed and Marks open up the box and provide genuine insight into the way neural nets work.

One problem with the book is that the terms "validation set" and "test set" are used inconsistently.

The best elementary textbook on using and programming NNs

Masters, T. (1993), Practical Neural Network Recipes in C++, Academic Press, ISBN 0-12-479040-2, US $45 incl. disks.
Book Webpage (Publisher): http://www.apcatalog.com/cgi-bin/AP?ISBN=0124790402&LOCATION=US&FORM=FORM2
Masters has written three exceptionally good books on NNs (the two others are listed below). He combines generally sound practical advice with some basic statistical knowledge to produce a programming text that is far superior to the competition (see "The Worst" below). Not everyone likes his C++ code (the usual complaint is that the code is not sufficiently OO) but, unlike the code in some other books, Masters's code has been successfully compiled and run by some readers of comp.ai.neural-nets. Masters's books are well worth reading even for people who have no interest in programming.

Masters, T. (1995) Advanced Algorithms for Neural Networks: A C++ Sourcebook, NY: John Wiley and Sons, ISBN 0-471-10588-0
Book Webpage (Publisher): http://www.wiley.com/
Additional Information: One has to search.
Clear explanations of conjugate gradient and Levenberg-Marquardt optimization algorithms, simulated annealing, kernel regression (GRNN) and discriminant analysis (PNN), Gram-Charlier networks, dimensionality reduction, cross-validation, and bootstrapping.

The best elementary textbooks on NN research

Review by Ian Cresswell:

What a relief! As a broad introductory text this is without any doubt the best currently available in its area. It doesn't include source code of any kind (normally this is badly written and compiler specific). The algorithms for many different kinds of simple neural nets are presented in a clear step by step manner in plain English.

Equally, the mathematics is introduced in a relatively gentle manner. There are no unnecessary complications or diversions from the main theme.

The examples that are used to demonstrate the various algorithms are detailed but (perhaps necessarily) simple.

There are bad things that can be said about most books. There are only a small number of minor criticisms that can be made about this one. More space should have been given to backprop and its variants because of the practical importance of such methods. And while the author discusses early stopping in one paragraph, the treatment of generalization is skimpy compared to the books by Weiss and Kulikowski or Smith listed above.

If you're new to neural nets and you don't want to be swamped by bogus ideas, huge amounts of intimidating looking mathematics, a programming language that you don't know etc. etc. then this is the book for you.

In summary, this is the best starting point for the outsider and/or beginner... a truly excellent text.

Anderson, J.A. (1995), An Introduction to Neural Networks, Cambridge,MA: The MIT Press, ISBN 0-262-01144-1.

Anderson provides an accessible introduction to the AI and neurophysiological sides of NN research, although the book is weak regarding practical aspects of using NNs. Recommended for classroom use if the instructor provides supplementary material on how to get good generalization.

The best intermediate textbooks on NNs

Bishop, C.M. (1995). Neural Networks for Pattern Recognition, Oxford: Oxford University Press. ISBN 0-19-853849-9 (hardback) or 0-19-853864-2 (paperback), xvii+482 pages.
Author's Webpage: http://neural-server.aston.ac.uk/People/bishopc/Welcome.html
Book Webpage (Publisher): http://www1.oup.co.uk/bin/readcat?Version=887069107&title=Neural+Networks+for+Pattern+Recognition&TOB=52305&H1=19808&H2=47489&H3=48287&H4=48306&count=1&style=full
This is definitely the best book on neural nets for practical applications for readers comfortable with calculus. Geoffrey Hinton writes in the foreword:
"Bishop is a leading researcher who has a deep understanding of the material and has gone to great lengths to organize it in a sequence that makes sense. He has wisely avoided the temptation to try to cover everything and has therefore omitted interesting topics like reinforcement learning, Hopfield networks, and Boltzmann machines in order to focus on the types of neural networks that are most widely used in practical applications. He assumes that the reader has the basic mathematical literacy required for an undergraduate science degree, and using these tools he explains everything from scratch. Before introducing the multilayer perceptron, for example, he lays a solid foundation of basic statistical concepts. So the crucial concept of overfitting is introduced using easily visualized examples of one-dimensional polynomials and only later applied to neural networks. An impressive aspect of this book is that it takes the reader all the way from the simplest linear models to the very latest Bayesian multilayer neural networks without ever requiring any great intellectual leaps."

Book Webpage (Publisher): http://www2.awl.com/gb/abp/sfi/computer.html
This is an excellent classic work on neural nets from the perspective of physics. Comments from readers of comp.ai.neural-nets: "My first impression is that this one is by far the best book on the topic. And it's below $30 for the paperback."; "Well written, theoretical (but not overwhelming)"; It provides a good balance of model development, computational algorithms, and applications. The mathematical derivations are especially well done"; "Nice mathematical analysis on the mechanism of different learning algorithms"; "It is NOT for mathematical beginner. If you don't have a good grasp of higher level math, this book can be really tough to get through."

The best advanced textbook covering NNs

Ripley, B.D. (1996) Pattern Recognition and Neural Networks, Cambridge: Cambridge University Press, ISBN 0-521-46086-7 (hardback), xii+403 pages.

Book Webpage (Publisher): http://www.cup.cam.ac.uk/
Additional Information: The Webpage includes errata and additional information, which hasn't been available at publishing time, for this book.
Brian Ripley's new book is an excellent sequel to Bishop (1995). Ripley starts up where Bishop left off, with Bayesian inference and statistical decision theory, and then covers some of the same material on NNs as Bishop but at a higher mathematical level. Ripley also covers a variety of methods that are not discussed, or discussed only briefly, by Bishop, such as tree-based methods and belief networks. While Ripley is best appreciated by people with a background in mathematical statistics, the numerous realistic examples in his book will be of interest even to beginners in neural nets.

Devroye, L., Gy\"orfi, L., and Lugosi, G. (1996), A Probabilistic Theory of Pattern Recognition, NY: Springer, ISBN 0-387-94618-7, vii+636 pages.
This book has relatively little material explicitly about neural nets, but what it has is very interesting and much of it is not found in other texts. The emphasis is on statistical proofs of universal consistency for a wide variety of methods, including histograms, (k) nearest neighbors, kernels (PNN), trees, generalized linear discriminants, MLPs, and RBF networks. There is also considerable material on validation and cross-validation. The authors say, "We did not scar the pages with backbreaking simulations or quick-and-dirty engineering solutions" (p. 7). The formula-to-text ratio is high, but the writing is quite clear, and anyone who has had a year or two of mathematical statistics should be able to follow the exposition.

Comments from readers of comp.ai.neural-nets:"Partly a textbook and partly a research monograph; introduces the basic concepts, techniques, and models related to neural networks and optimization, excluding rigorous mathematical details. Accessible to a wide readership with a differential calculus background. The main coverage of the book is on recurrent neural networks with continuous state variables. The book title would be more appropriate without mentioning signal processing. Well edited, good illustrations."

Brown and Harris rely on the fundamental insight that that a fuzzy system is a nonlinear mapping from an input space to an output space that can be parameterized in various ways and therefore can be adapted to data using the usual neural training methods (see "What is backprop?") or conventional numerical optimization algorithms (see "What are conjugate gradients, Levenberg-Marquardt, etc.?"). Their approach makes clear the intimate connections between fuzzy systems, neural networks, and statistical methods such as B-spline regression.

Kosko, B. (1997), Fuzzy Engineering, Upper Saddle River, NJ: Prentice Hall.
Kosko's new book is a big improvement over his older neurofuzzy book and makes an excellent sequel to Brown and Harris (1994).

The authors try to translate mathematical formulas into English. The results are likely to disturb people who appreciate either mathematics or English. Have the authors never heard that "a picture is worth a thousand words"? What few diagrams they have (such as the one on p. 74) tend to be confusing. Their jargon is peculiar even by NN standards; for example, they refer to target values as "mentor inputs" (p. 66). The authors do not understand elementary properties of error functions and optimization algorithms. For example, in their discussion of the delta rule, the authors seem oblivious to the differences between batch and on-line training, and they attribute magical properties to the algorithm (p. 71):

[The on-line delta] rule always takes the most efficient route from the current position of the weight vector to the "ideal" position, based on the current input pattern. The delta rule not only minimizes the mean squared error, it does so in the most efficient fashion possible--quite an achievement for such a simple rule.
While the authors realize that backpropagation networks can suffer from local minima, they mistakenly think that counterpropagation has some kind of global optimization ability (p. 202):
Unlike the backpropagation network, a counterpropagation network cannot be fooled into finding a local minimum solution. This means that the network is guaranteed to find the correct response (or the nearest stored response) to an input, no matter what.
But even though they acknowledge the problem of local minima, the authors are ignorant of the importance of initial weight values (p. 186):
To teach our imaginary network something using backpropagation, we must start by setting all the adaptive weights on all the neurodes in it to random values. It won't matter what those values are, as long as they are not all the same and not equal to 1.
Like most introductory books, this one neglects the difficulties of getting good generalization--the authors simply declare (p. 8) that "A neural network is able to generalize"!

Comments from readers of comp.ai.neural-nets: "The book was developed out of a course on neural-network models with computer demonstrations that was taught by the authors to Physics students. The book comes together with a PC-diskette. The book is divided into three parts: (1) Models of Neural Networks; describing several architectures and learing rules, including the mathematics. (2) Statistical Physiscs of Neural Networks; "hard-core" physics section developing formal theories of stochastic neural networks. (3) Computer Codes; explanation about the demonstration programs. First part gives a nice introduction into neural networks together with the formulas. Together with the demonstration programs a 'feel' for neural networks can be developed."

Books with Source Code (C, C++)

Blum, Adam (1992), Neural Networks in C++, Wiley.

Review by Ian Cresswell. (For a review of the text, see "The Worst" below.)

Mr Blum has not only contributed a masterpiece of NN inaccuracy but also seems to lack a fundamental understanding of Object Orientation.

The excessive use of virtual methods (see page 32 for example), the inclusion of unnecessary 'friend' relationships (page 133) and a penchant for operator overloading (pick a page!) demonstrate inability in C++ and/or OO.

The introduction to OO that is provided trivialises the area and demonstrates a distinct lack of direction and/or understanding.

The public interfaces to classes are overspecified and the design relies upon the flawed neuron/layer/network model.

There is a notable disregard for any notion of a robust class hierarchy which is demonstrated by an almost total lack of concern for inheritance and associated reuse strategies.

The attempt to rationalise differing types of Neural Network into a single very shallow but wide class hierarchy is naive.

The general use of the 'float' data type would cause serious hassle if this software could possibly be extended to use some of the more sensitive variants of backprop on more difficult problems. It is a matter of great fortune that such software is unlikely to be reusable and will therefore, like all good dinosaurs, disappear with the passage of time.

The irony is that there is a card in the back of the book asking the unfortunate reader to part with a further $39.95 for a copy of the software (already included in print) on a 5.25" disk.

The author claims that his work provides an 'Object Oriented Framework ...'. This can best be put in his own terms (Page 137):


... garble(float noise) ...

Swingler, K. (1996), Applying Neural Networks: A Practical Guide, London: Academic Press.

Review by Ian Cresswell. (For a review of the text, see "The Worst" below.)

Before attempting to review the code associated with this book it should be clearly stated that it is supplied as an extra--almost as an afterthought. This may be a wise move.

Although not as bad as other (even commercial) implementations, the code provided lacks proper OO structure and is typical of C++ written in a C style.

Style criticisms include:

  1. The use of public data fields within classes (loss of encapsulation).
  2. Classes with no protected or private sections.
  3. Little or no use of inheritance and/or run-time polymorphism.
  4. Use of floats not doubles (a common mistake) to store values for connection weights.
  5. Overuse of classes and public methods. The network class has 59 methods in its public section.
  6. Lack of planning is evident for the construction of a class hierarchy.
This code is without doubt written by a rushed C programmer. Whilst it would require a C++ compiler to be successfully used, it lacks the tight (optimised) nature of good C and the high level of abstraction of good C++.

In a generous sense the code is free and the author doesn't claim any expertise in software engineering. It works in a limited sense but would be difficult to extend and/or reuse. It's fine for demonstration purposes in a stand-alone manner and for use with the book concerned.

If you're serious about nets you'll end up rewriting the whole lot (or getting something better).

The Worst

How not to use neural nets in any programming language

Blum, Adam (1992), Neural Networks in C++, NY: Wiley.

Welstead, Stephen T. (1994), Neural Network and Fuzzy Logic Applications in C/C++, NY: Wiley.

(For a review of Blum's source code, see "Books with Source Code" above.)

Both Blum and Welstead contribute to the dangerous myth that any idiot can use a neural net by dumping in whatever data are handy and letting it train for a few days. They both have little or no discussion of generalization, validation, and overfitting. Neither provides any valid advice on choosing the number of hidden nodes. If you have ever wondered where these stupid "rules of thumb" that pop up frequently come from, here's a source for one of them:

"A rule of thumb is for the size of this [hidden] layer to be somewhere between the input layer size ... and the output layer size ..." Blum, p. 60.
(John Lazzaro tells me he recently "reviewed a paper that cited this rule of thumb--and referenced this book! Needless to say, the final version of that paper didn't include the reference!")

Blum offers some profound advice on choosing inputs:

"The next step is to pick as many input factors as possible that might be related to [the target]."
Blum also shows a deep understanding of statistics:
"A statistical model is simply a more indirect way of learning correlations. With a neural net approach, we model the problem directly." p. 8.
Blum at least mentions some important issues, however simplistic his advice may be. Welstead just ignores them. What Welstead gives you is code--vast amounts of code. I have no idea how anyone could write that much code for a simple feedforward NN. Welstead's approach to validation, in his chapter on financial forecasting, is to reserve two cases for the validation set!

My comments apply only to the text of the above books. I have not examined or attempted to compile the code.

An impractical guide to neural nets

Swingler, K. (1996), Applying Neural Networks: A Practical Guide, London: Academic Press.

(For a review of the source code, see "Books with Source Code" above.)

This book has lots of good advice liberally sprinkled with errors, incorrect formulas, some bad advice, and some very serious mistakes. Experts will learn nothing, while beginners will be unable to separate the useful information from the dangerous. For example, there is a chapter on "Data encoding and re-coding" that would be very useful to beginners if it were accurate, but the formula for the standard deviation is wrong, and the description of the softmax function is of something entirely different than softmax (see What is a softmax activation function?). Even more dangerous is the statement on p. 28 that "Any pair of variables with high covariance are dependent, and one may be chosen to be discarded." Although high correlations can be used to identify redundant inputs, it is incorrect to use high covariances for this purpose, since a covariance can be high simply because one of the inputs has a high standard deviation.

The most ludicrous thing I've found in the book is the claim that Hecht-Neilsen used Kolmogorov's theorem to show that "you will never require more than twice the number of hidden units as you have inputs" (p. 53) in an MLP with one hidden layer. Actually, Hecht-Neilsen, says "the direct usefulness of this result is doubtful, because no constructive method for developing the [output activation] functions is known." Then Swingler implies that V. Kurkova (1991, "Kolmogorov's theorem is relevant," Neural Computation, 3, 617-622) confirmed this alleged upper bound on the number of hidden units, saying that, "Kurkova was able to restate Kolmogorov's theorem in terms of a set of sigmoidal functions." If Kolmogorov's theorem, or Hecht-Nielsen's adaptation of it, could be restated in terms of known sigmoid activation functions in the (single) hidden and output layers, then Swingler's alleged upper bound would be correct, but in fact no such restatement of Kolmogorov's theorem is possible, and Kurkova did not claim to prove any such restatement. Swingler omits the crucial details that Kurkova used two hidden layers, staircase-like activation functions (not ordinary sigmoidal functions such as the logistic) in the first hidden layer, and a potentially large number of units in the second hidden layer. Kurkova later estimated the number of units required for uniform approximation within an error epsilon as nm(m+1) in the first hidden layer and m^2(m+1)^n in the second hidden layer, where n is the number of inputs and m "depends on epsilon/||f|| as well as on the rate with which f increases distances." In other words, Kurkova says nothing to support Swinglers advice (repeated on p. 55), "Never choose h to be more than twice the number of input units." Furthermore, constructing a counter example to Swingler's advice is trivial: use one input and one output, where the output is the sine of the input, and the domain of the input extends over many cycles of the sine wave; it is obvious that many more than two hidden units are required. For some sound information on choosing the number of hidden units, see How many hidden units should I use?

Choosing the number of hidden units is one important aspect of getting good generalization, which is the most crucial issue in neural network training. There are many other considerations involved in getting good generalization, and Swingler makes several more mistakes in this area:

While Swingler has some knowldege of statistics, his expertise is not sufficient for him to detect that certain articles on neural nets are statistically nonsense. For example, on pp. 139-140 he uncritically reports a method that allegedly obtains error bars by doing a simple linear regression on the target vs. output scores. To a trained statistician, this method is obviously wrong (and, as usual in this book, the formula for variance given for this method on p. 150 is wrong). On p. 110, Swingler reports an article that attempts to apply bootstrapping to neural nets, but this article is also obviously wrong to anyone familiar with bootstrapping. While Swingler cannot be blamed entirely for accepting these articles at face value, such misinformation provides yet more hazards for beginners.

Swingler addresses many important practical issues, and often provides good practical advice. But the peculiar combination of much good advice with some extremely bad advice, a few examples of which are provided above, could easily seduce a beginner into thinking that the book as a whole is reliable. It is this danger that earns the book a place in "The Worst" list.

Bad science writing

Dewdney, A.K. (1997), Yes, We Have No Neutrons: An Eye-Opening Tour through the Twists and Turns of Bad Science, NY: Wiley.

This book, allegedly an expose of bad science, contains only one chapter of 19 pages on "the neural net debacle" (p. 97). Yet this chapter is so egregiously misleading that the book has earned a place on "The Worst" list. A detailed criticism of this chapter, along with some other sections of the book, can be found at ftp://ftp.sas.com/pub/neural/badscience.html. Other chapters of the book are reviewed in the November, 1997, issue of Scientific American.

Title:   The Behavioral and Brain Sciences

Publish: Cambridge University Press

Remark:  (Expensive as hell, I'm sure.)

         This is a delightful journal that encourages discussion on a

         variety of controversial topics.  I have especially enjoyed

         reading some papers in there by Dana Ballard and Stephen

         Grossberg (separate papers, not collaborations) a few years

         back.  They have a really neat concept: they get a paper,

         then invite a number of noted scientists in the field to

         praise it or trash it.  They print these commentaries, and

         give the author(s) a chance to make a rebuttal or

         concurrence.  Sometimes, as I'm sure you can imagine, things

         get pretty lively.  I'm reasonably sure they are still at

         it--I think I saw them make a call for reviewers a few

         months ago.  Their reviewers are called something like

         Behavioral and Brain Associates, and I believe they have to

         be nominated by current associates, and should be fairly

         well established in the field.  That's probably more than I

         really know about it but maybe if you post it someone who

         knows more about it will correct any errors I have made.

         The main thing is that I liked the articles I read. (Note:

  7. Machine Learning Papers

    http://gubbio.cs.berkeley.edu/mlpapers/


------------------------------------------------------------------------

Subject: How to benchmark learning methods?

The NN benchmarking resources page at http://wwwipd.ira.uka.de/~prechelt/NIPS_bench.html was created after a NIPS 1995 workshop on NN benchmarking. The page contains pointers to various papers on proper benchmarking methodology and to various sources of datasets.

Benchmark studies require some familiarity with the statistical design and analysis of experiments. There are many textbooks on this subject, of which Cohen (1995) will probably be of particular interest to researchers in neural nets and machine learning (see also the review of Cohen's book by Ron Kohavi in the International Journal of Neural Systems, which can be found on-line at http://robotics.stanford.edu/users/ronnyk/ronnyk-bib.html).

    Delve is a standardised, copyrighted environment designed to evaluate the performance of learning methods. Delve makes it possible for users to compare their learning methods with other methods on many datasets. The Delve learning methods and evaluation procedures are well documented, such that meaningful comparisons can be made. The data collection includes not only isolated data sets, but "families" of data sets in which properties of the data, such as number of inputs and degree of nonlinearity or noise, are systematically varied. The Delve web page is at http://www.cs.toronto.edu/~delve/

  6. NIST special databases of the National Institute Of Standards And Technology:

    Several large databases, each delivered on a CD-ROM. Here is a quick list. Here are example descriptions of two of these databases:

    NIST special database 2: Structured Forms Reference Set (SFRS)

    The NIST database of structured forms contains 5,590 full page images of simulated tax forms completed using machine print. THERE IS NO REAL TAX DATA IN THIS DATABASE. The structured forms used in this database are 12 different forms from the 1988, IRS 1040 Package X. These include Forms 1040, 2106, 2441, 4562, and 6251 together with Schedules A, B, C, D, E, F and SE. Eight of these forms contain two pages or form faces making a total of 20 form faces represented in the database. Each image is stored in bi-level black and white raster format. The images in this database appear to be real forms prepared by individuals but the images have been automatically derived and synthesized using a computer and contain no "real" tax data. The entry field values on the forms have been automatically generated by a computer in order to make the data available without the danger of distributing privileged tax information. In addition to the images the database includes 5,590 answer files, one for each image. Each answer file contains an ASCII representation of the data found in the entry fields on the corresponding image. Image format documentation and example software are also provided. The uncompressed database totals approximately 5.9 gigabytes of data.

    NIST special database 3: Binary Images of Handwritten Segmented Characters (HWSC)

    Contains 313,389 isolated character images segmented from the 2,100 full-page images distributed with "NIST Special Database 1". 223,125 digits, 44,951 upper-case, and 45,313 lower-case character images. Each character image has been centered in a separate 128 by 128 pixel region, error rate of the segmentation and assigned classification is less than 0.1%. The uncompressed database totals approximately 2.75 gigabytes of image data and includes image format documentation and example software.

    The system requirements for all databases are a 5.25" CD-ROM drive with software to read ISO-9660 format. Contact: Darrin L. Dimmick; dld@magi.ncsl.nist.gov; (301)975-4147

    The prices of the databases are between US$ 250 and 1895 If you wish to order a database, please contact: Standard Reference Data; National Institute of Standards and Technology; 221/A323; Gaithersburg, MD 20899; Phone: (301)975-2208; FAX: (301)926-0416

Problems are for example: fluctuations in a far-infrared laser; Physiological data of patients with sleep apnea; High frequency currency exchange rate data; Intensity of a white dwarf star; J.S. Bachs final (unfinished) fugue from "Die Kunst der Fuge"

    Some of the datasets were used in a prediction contest and are described in detail in the book "Time series prediction: Forecasting the future and understanding the past", edited by Weigend/Gershenfield, Proceedings Volume XV in the Santa Fe Institute Studies in the Sciences of Complexity series of Addison Wesley (1994).

  10. USENIX Faces

    The USENIX faces archive is a public database, accessible by ftp, that can be of use to people working in the fields of human face recognition, classification and the like. It currently contains 5592 different faces (taken at USENIX conferences) and is updated twice each year. The images are mostly 96x128 greyscale frontal images and are stored in ascii files in a way that makes it easy to convert them to any usual graphic format (GIF, PCX, PBM etc.). Source code for viewers, filters, etc. is provided. Each image file takes approximately 25K.

    For further information, see ftp://src.doc.ic.ac.uk/pub/packages/faces/README Do NOT do a directory listing in the top directory of the face archive, as it contains over 2500 entries!

    According to the archive administrator, Barbara L. Dijker (barb.dijker@labyrinth.com), there is no restriction to use them. However, the image files are stored in separate directories corresponding to the Internet site to which the person represented in the image belongs, with each directory containing a small number of images (two in the average). This makes it difficult to retrieve by ftp even a small part of the database, as you have to get each one individually.
    A solution, as Barbara proposed me, would be to compress the whole set of images (in separate files of, say, 100 images) and maintain them as a specific archive for research on face processing, similar to the ones that already exist for fingerprints and others. The whole compressed database would take some 30 megabytes of disk space. I encourage anyone willing to host this database in his/her site, available for anonymous ftp, to contact her for details (unfortunately I don't have the resources to set up such a site).

    Please consider that UUNET has graciously provided the ftp server for the FaceSaver archive and may discontinue that service if it becomes a burden. This means that people should not download more than maybe 10 faces at a time from uunet.

    A last remark: each file represents a different person (except for isolated cases). This makes the database quite unsuitable for training neural networks, since for proper generalisation several instances of the same subject are required. However, it is still useful for use as testing set on a trained network.

  11. Linguistic Data Consortium

    The Linguistic Data Consortium (URL: http://www.ldc.upenn.edu/ldc/noframe.html) is an open consortium of universities, companies and government research laboratories. It creates, collects and distributes speech and text databases, lexicons, and other resources for research and development purposes. The University of Pennsylvania is the LDC's host institution. The LDC catalog includes pronunciation lexicons, varied lexicons, broadcast speech, microphone speech, mobile-radio speech, telephone speech, broadcast text, conversation text, newswire text, parallel text, and varied text, at widely varying fees.
