[Data structs] decisiontree DL : 0: 这个是一个关于建立决策树的python程序．本程序运用entropy来决定splitting point.处理的数据得在程序中输入．希望大家觉得有用-This is a decision tree on the establishment of procedures for the python. Entropy of the process to decide the use of splitting point. Deal with the data was input in the process. Hope that we find useful

[Data structs] huffman DL : 0: 霍夫曼编码（Huffman Coding）是一种编码方式，是一种用于无损数据压缩的熵编码（权编码）算法。-Huffman coding (Huffman Coding) is an encoding is a lossless data compression entropy coding (right encoding) for the algorithm.

[Data structs] HuffmanTree DL : 0: 霍夫曼编码是一种编码方式，是一种用于无损数据压缩的熵编码（权编码）算法。用变长编码表对源符号（如文件中的一个字母）进行编码，其中变长编码表是通过一种评估来源符号出现机率的方法得到的，出现机率高的字母使用较短的编码，反之出现机率低的则使用较长的编码，这便使编码之后的字符串的平均长度、期望值降低，从而达到无损压缩数据的目的。-Huffman coding is a coding is a lossless data compression entropy coding (right coding) for the algorithm. With variable-length coding tables on the source symbol (such as a file in a letter) to encode, which is a method of variable length coding table through an assessment of the probability of occurrence of the source symbols obtained letters appear high probability using a shorter code, and vice versa low appears machine code using a longer, which would make the average length of the string after encoding, expectations are lower, so as to achieve the purpose of lossless data compression.
