Abstract

We review different categories of associative processors with attention to the properties of their key and recollection vectors, the test procedures to be used and the performance measures to be used to compare various associative processors. We review new pseudoinverse and Ho-Kashyap associative processors and robust versions of each. Q uantitative data is presented on the performance of these new pattern recognition associative processors. In all cases we show significant improvement over prior data with M >> N (M is the number of key/recollection vectors pairs stored and N is the dimensionality of the input key vector). Quantization of the number of analog levels and comparisons of various recollection vector encodings are considered.
