用法

将依赖项添加到你的composer.json文件中。

  "require": {
    "mr5/bayes":"dev-master"
  }

训练

<?php
  use Mr5\Bayes\Classifier;
  use Mr5\Bayes\Tokenizer\WhitespaceAndPunctuationTokenizer;
  use Mr5\Bayes\Storage\ArrayStorage;
  
  $storage = new ArrayStorage();
  $tokenizer = new WhitespaceAndPunctuationTokenizer();
  $classifier = new Classifier($storage);
  
  $classifier->learn('english', $tokenizer->tokenize('This is english'));
  $classifier->learn('french', $tokenizer->tokenize('Je suis Hollandais'));
  
  $probabilities = $classifier->categoriesProbability(
      $tokenizer->tokenize('This is a naive bayes classifier')
  );
  
  var_dump($probabilities);

将输出

array(2) {
  ["english"]=>
  float(99.91)
  ["french"]=>
  float(50)
}
