simplebayes 1.5.8

基于内存的可选持久性朴素贝叶斯文本分类器。

This work is heavily inspired by the python "redisbayes" module found here:
[https://github.com/jart/redisbayes] and [https://pypi.python.org/pypi/redisbayes]

I've elected to write this to alleviate the network/time requirements when
using the bayesian classifier to classify large sets of text, or when
attempting to train with very large sets of sample data.

生成状态

安装

sudo pip install simplebayes

基本用法

importsimplebayesbayes=simplebayes.SimpleBayes()bayes.train('good','sunshine drugs love sex lobster sloth')bayes.train('bad','fear death horror government zombie')assertbayes.classify('sloths are so cute i love them')=='good'assertbayes.classify('i would fear a zombie and love the government')=='bad'printbayes.score('i fear zombies and love the government')bayes.untrain('bad','fear death')assertbayes.tally('bad')==3

缓存使用

importsimplebayesbayes=simplebayes.SimpleBayes(cache_path='/my/cache/')# Cache file is '/my/cache/_simplebayes.pickle'# Default cache_path is '/tmp/'ifnotbayes.cache_train():# Unable to load cache data, so we're training itbayes.train('good','sunshine drugs love sex lobster sloth')bayes.train('bad','fear death horror government zombie')# Saving the cache so next time the training won't be neededbayes.persist_cache()
