前言

Pattern recognition has a long and respectable history within engineer-ing, especially for military applications, but the cost of the hardwareboth to acquire the data （signals and images） and to compute theanswers made it for many years a rather specialist subject. Hardwareadvances have made the concerns of pattern recognition of much widerapplicability. In essence it covers the following problem:'Given some examples of complex signals and the correctdecisions for them, make decisions automatically for a streamof future examples.'There are many examples from everyday life:Name the species of a flowering plant.Grade bacon rashers from a visual image.Classify an X-ray image of a tumour as cancerous or benign.Decide to buy or sell a stock option.Give or refuse credit to a shopper.Many of these are currently performed by human experts, but it isincreasingly becoming feasible to design automated systems to replacethe expert and either perform better （as in credit scoring） or 'clone' theexpert （as in aids to medical diagnosis）.Neural networks have arisen from analogies with models of the waythat humans might approach pattern recognition tasks, although theyhave developed a long way from the biological roots. Great claims havebeen made for these procedures, and although few of these claims havewithstood careful scrutiny, neural network methods have had greatimpact on pattern recognition practice. A theoretical understanding ofhow they work is still under construction, and is attempted here byviewing neural networks within a statistical framework, together withmethods developed in the field of machine learning.One of the aims of this book is to be a reference resource, so almostall the results used are proved （and the remainder are given referencesto complete proofs）. The proofs are often original.

章节摘录

插图：The calculations here are from Hjort （1986）; versions of these for-mulae are given by Aitchison & Dunsmore （1975） （up to the differencesin the meaning of their multivariate t） and Geisser （1993）. This ap-proach is originally due to Geisser （1964, 1966）.The differences between the predictive and plug-in approaches willbe small or zero for roughly equally prevalent classes. In other cases,for example screening for rare diseases or when very few data areavailable, the differences can be dramatic as shown by the examples inAitchison & Dunsmore （1975, 11.5-11.6）. The latter do have groupswith nk only slightly greater than p, for example p = 8 and n2 = 11when fitting a covariance matrix to each class, which would be seenas over-fitting in the plug-in approach. （Indeed, one might choose notto use all the variables, or perhaps to restrict the class of covariancematrices considered.）Aitchison et al. （1977） conducted a small-sample simulation compar-ison of the plug-in and predictive methods for two multivariate normalpopulations. They were （correctly） criticized by Moran & Murphy（1979） for using the accuracy of the estimation of the log=odds as thebasis of comparison rather than error rates, and for including mainlyequal sample sizes of the two classes. Moran & Murphy's results showvery little difference in the error rates, and show that for estimationof the log-odds the debiasing methods of Section 2.5 are effective inremoving the dramatic optimism of the plug-in method where it occurs.
