一.实验原理1.Huffman编码1)HuffmanCoding(霍夫曼编码)是一种无失真编码的编码方式,Huffman编码是可编长编码(VLC)的一种。2)Huffman编码基于信源的概率统计模型,它的基本思路是:出现概率大的信源符号编短码,出现概率小的编长码。从而实现平均码长最小。3)在程序实现中常使用一种叫做树的数据结构实现Huffman编码,由...
1 原理哈夫曼编码(Huffman Coding),又称霍夫曼编码,是一种编码方式,哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法,该方法完全依据字符出现概率来构造异字头的平均长度最短的码字,有…
The most popular entropy-based encoding technique is the Huffman code [1] . It provides the least amount of information units (bits) per source symbol. This short article describes how it works. The first step in the Huffman algorithm consists in creating a series of source reductions, by ...

DEEP COMPRESSION: COMPRESSING DEEP NEURAL NETWORKS WITH PRUNING, TRAINED QUANTIZATION AND HUFFMAN CODING 论文笔记 摘要 神经网络既是计算密集型又是内存密集型,使得它们难以部署在具有有限硬件资源的嵌入式系统上。为了解决这个限制,我们引入了“深度压缩”,一个三阶段流水线:修剪,训练量化和霍夫曼编码,它们协同工作...
