An Introduction to the Design of Pattern Recognition Devices

Abstract: This paper presents the answer to a problem which may have puzzled many of the readers: given a multivariate probability density function and its marginals, how does one find the other multivariate densities which have the same set of marginals? The answer is that all the multivariate densities may be found by applying a particular transformation (called the transformation) a number of times to the product of the marginals. It thus becomes possible, by hill-clim£ ing, to find the "WDrst" or the "best" multivariate density which is concomitant with a specified set of marginals. This new technique is important in connection with problems where the designer only has access to the marginals and where he wants to bound functions of the multivariate density. Fo~ illustration, the tec! nique is used to solve two hitherto unsolved problems, one in the field of electronic circuit reliability, and one in the field of pattern recognition.

Natural language, linguistic processing, and speech understanding : recent research and future goals

Abstract: : The report contains a discussion of artificial intelligence, computer processing of natural-language data programming languages for problem-solving systems, and structural (contextual, linguistic) pattern recognition. It includes an in-depth survey of recent research results that includes examples of deduction, text recognition, and dialogue by and with computers followed by discussion of speech data, applications of understand-software, and suggestions for further research.
