A memory-based, optional-persistence naïve bayesian text classifier.
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.
sudo pip install simplebayes
import simplebayes bayes = simplebayes.SimpleBayes() bayes.train('good', 'sunshine drugs love sex lobster sloth') bayes.train('bad', 'fear death horror government zombie') assert bayes.classify('sloths are so cute i love them') == 'good' assert bayes.classify('i would fear a zombie and love the government') == 'bad' print bayes.score('i fear zombies and love the government') bayes.untrain('bad', 'fear death') assert bayes.tally('bad') == 3
import simplebayes bayes = simplebayes.SimpleBayes(cache_path='/my/cache/') # Cache file is '/my/cache/_simplebayes.pickle' # Default cache_path is '/tmp/' if not bayes.cache_train(): # Unable to load cache data, so we're training it bayes.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 needed bayes.persist_cache()
import simplebayes def my_tokenizer(sample): return sample.split() bayes = simplebayes.SimpleBayes(tokenizer=my_tokenizer)
