Description: ) 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.

Description: matlab数据结构 算法工具箱, 包括堆栈 队列 2叉树 红黑树 -Data Structures & Algorithms Toolbox
====================================
The Data Structures & Algorithms Toolbox provides advanced data
structures and algorithms for the Matlab(r) 5 environment. It implements
functions to create and destroy singly and doubly linked list, stack,
queue, binary tree and red-black (balanced) binary tree. Data elements
can be inserted, deleted or searched for. A graphical representation of
trees can be shown. All algorithms are clearly written as m-files, which
allows the toolbox to be used as a teaching aid in educational data
structures courses. This is the first implementation available of
advanced datatypes, common in other languages, for Matlab. Platform: |

Description: his algorithm was proposed by Quinlan (1993). The C4.5 algorithm generates a classification-decision tree for the given data-set by recursive partitioning of data. The decision is grown using Depth-first strategy. The algorithm considers all the possible tests that can split the data set and selects a test that gives the best information gain. For each discrete attribute, one test with outcomes as many as the number of distinct values of the attribute is considered. For each continuous attribute, binary tests involving every distinct values of the attribute are considered. In order to gather the entropy gain of all these binary tests efficiently, the training data set belonging to the node in consideration is sorted for the values of the continuous attribute and the entropy gains of the binary cut based on each distinct values are calculated in one scan of the sorted data. This process is repeated for each continuous attributes. Platform: |
