Abstract
A neural fuzzy data classifier for handwritten character classification is provided. The classifier has an I/O circuit for inputting and outputting a plurality of membership functions. An input buffer receives a to-be-recognized character having a plurality of input features for generating a plurality of features values. A main computation unit comprising a computation array and a local thresholds block store the plurality of membership functions and receives the plurality of features values to generate a plurality of current-type weights. A difference circuit block compares the current output from the computation array and local thresholds lock. A plurality of switched-current integrators receives the plurality of current-type weights for generating a plurality of synthesis weights. A k-WTA circuit outputs the plurality of synthesis weights as well as the corresponding characters in an order of magnitude and the 10 current threshold block compares the plurality of synthesis weights and output a digital voltage.
