The Huffman tree can be rebuild from the net::TransportSecurityStateSource::huffman_tree array. Web1 okt. 2015 · Our method first prunes the network by learning only the important connections. Next, we quantize the weights to enforce weight sharing, finally, we apply Huffman coding. After the first two steps we retrain the network to fine tune the remaining connections and the quantized centroids.
