Two hybrid fuzzy neural systems are developed and applied to handwritt
en word recognition. The word recognition system requires a module tha
t assigns character class membership values to segments of images of h
andwritten words, The module must accurately represent ambiguities bet
ween character classes and assign low membership values to a wide vari
ety of noncharacter segments resulting from erroneous segmentations, E
ach hybrid is a cascaded system, The first stage of both is a self-org
anizing feature map (SOFM), The second stages map distances into membe
rship values, The third stage of one system is a multilayer perceptron
(MLP), The third stage of the other is a bank of Choquet fuzzy integr
als (FI's), The two systems are compared individually and as a combina
tion to the baseline system, The new systems each perform better than
the baseline system, The MLP system slightly outperforms the FI system
; but the combination of the two outperforms the individual systems wi
th a small increase in computational cost over the MLP system, Recogni
tion rates of over 92% are achieved with a lexicon set having average
size of 100, Experiments were performed on a standard test set from th
e SUNY/USPS CD-ROM database.
