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.)
