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.

With Huffman’s scheme, a common character such as “a” or “e” might be encoded with perhaps just two bits and less frequently used characters like “q” or “#” would be encoded with a longer bit string. the death clock 死亡时钟
