Abstract
Levels of cross-correlation between pairs of original filters in the layers of a convolutional neural network (CNN) are determined and used in pruning the filters. The pruning includes, for one or more pairs of the pairs of original filters having a level of cross-correlation that satisfies a pruning threshold, determining a scale factor between first and second filters of the one or more pairs, and storing data that identify the first filter, the second filter, and the scale factor. The pruning further includes modifying the initial CNN into a modified CNN by removing the second filter of the one or more pairs and adjusting convolution logic of the CNN, and adding regeneration logic to the modified CNN. The regeneration logic generates an output channel corresponding to the second filter of the one or more pairs based on the scale factor and an output channel produced by the first filter.
