huffman_coding
) Compression using huffman code
-with a number of bits k per code word
-provide huffman table
Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.

说明: 预处理工具包括:主成分Analysi 小号(PCA),白化,过滤:高通滤波(HPF),低通滤波(LPF),子带滤波器(巴特沃斯,切比雪夫,椭圆)用的滤波器,频率子带和可调顺序子带的数量)或用户定义的 预处理功能。
后处理工具实际上包括:通过去除不想要的组件,噪声或伪像,对原始原始数据进行压缩和重建(“清理”)。
该算法不仅可以执行ICA,还可以执行二阶统计盲源分离(BSS),稀疏分量分析(SCA),非负矩阵分解(NMF),平滑分量分析(SmoCA),因子分析(FA)和任何其他可能的矩阵X = HS + N或 Y = WX形式的因式分解,其中H = W +是混合矩阵或基本向量矩阵。X是观测数据的矩阵,S是原始数据的矩阵,N表示其他噪声的矩阵。
ICA / BSS算法是纯数学公式,功能强大,但机械程序却很复杂:机械得到最佳实施后,用户要做的工作不多。ICALAB的成功和有效使用在很大程度上取决于先验知识,常识以及对预处理和后处理工具的适当使用。(icalab toolboxes for signal process, based on the software MATLAB.)
