Abstract
This work proposes a new method, KernelCanvas, that is adequate to the Weightless Neural Model known asWiSARD for generating a fixed length binary input from spatio-temporal patterns. The method, based on kernel distances, issimple to implement and scales linearly to the number of kernels. Five different datasets were used to evaluate its performance in comparison with more widely employed approaches. One dataset was related to human movements, two to handwritten characters, one to speaker recognition and the last one to speech recognition. The KernelCanvas combined with WiSARD classifier approach frequently achieved the highest scores, sometimes losing only forthe much slower K-Nearest Neighbors approach. In comparison with other results in the literature, our model has performed better or very close to them in all datasets.
