- ldpc decode c程序 Iterative probabilistic decoding of linear block codes.Based on Pearl s Belief Propagation in Bayesian Networks.This version utilizes object to define graph nodes and LOG-LIKELIHOOD RATIOS. Much improved in terms of speed compared t
072282
- 提出了一种自动构造特定领域本体的方法，该方法应用术语抽取和多重聚类技术。在术语抽取阶段，通过术语在专业语料与背景语料中出现概率的对比，采用LLR公式对术语进行评分，取得了更好的抽取效果。在层级关系发现过程中，采用上下文共现信息结合HowNet中词语的语义相似度，进行术语间相似度度量，力求获得术语间最合理的相关状况。同时改进了k-medoids聚类算法，更准确地发现术语的层级关系，进而构造出特定领域的本体。-This paper presents an approach to mining dom
Maximum-Likelihood-Estimation
- 用MATLAB编写代码,在经济和金融中法对连续时间过程实现了封闭的最大似然估计方法-The code, written in MATLAB, implements the closed-form maximum-likelihood estimation method for continuous-time processes in economics and finance. First, the code maximizes the log-likelihood function and d
LLR--BP
- LDPC码的软判决译码算法，概率域LLR—BP算法，其中，概率信息以对数似然比的形式表示。-The decoding algorithm of LDPC . The LLP-BP algorithm of probability field,in which,the probability informationv expressed by the form of log likelihood ratio.
copula_functions
- 利用极大似然估计估计出copula函数参数后，求解常见的copula函数的对数似然值。(After estimating the parameters of the copula function by using the MLE, the log likelihood values of the common Copula Functions are solved.)
