Huffman coding (lossless compression). The basic steps of the compression are: 1. Divide the input data to 8 groups by K-means clustering algorithm; 2. Represent the input data by their corresponding cluster IDs (we have 3000 pairs of floating numbers as input, thus we have 3000 integers as their cluster IDs); 3.
