[comp.ai.neural-nets] Translation-Invariant Pattern Recognizer NN's

linco@eng.umd.edu (Sam Lin) (02/08/90)

In their paper, "Neural Nets for Adaptive Filtering and Adaptive
Pattern Recognition (IEEE Computer, March 1988),"  Bernard Widrow and
Rodney Winter describe a feed-forward network for pattern
recognition, whose responses are invariant to translation, rotation,
and scale change of the input pattern.  This network is based on
multiple ADALINE neurodes, and the Madaline rule II (MRII) training
method.  Does anyone know where I can find further information on
this network?  Is there a follow-up article?  Sources of information on the
translation/rotation/scale invariance of backpropagation (or other
networks) in pattern recognition would also be appreciated.
Thanks in advance.

     Dr. Widrow gave a presentation at the 1989 WESCON in S.F.  He 
presented his original 1960 paper where ADALINE and Madaline were
described (first time in WESCON history where a paper was presented
twice).  Anyway, the paper was reprinted in the conference proceedings.
     Hope this helps.

The original 1960  paper by Widrow and Hoff, "Adaptive switching circuits",
is also re-printed in the book "Neurocomputing : Foundations of research" 
eds- Anderson & Rosenfeld, MIT press (1988).
	In thier introduction to this paper the editors refer you to the 
book "Adaptive signal processing" - Widrow & Stearns, Prentice Hall (1985)
for more details about the LMS (Least Mean Square) algorithm, its variants
and their use in signal processing.
