# Bayesian Network
A simple Bayesian network based on Baye's rule and the conditional independence assumption.
## Example Usage
```javascript
const classifier = new BayesianNetwork();
classifier.addDocument("hello you are amazing", "positive");
classifier.addDocument("today is a beautiful day", "positive");
classifier.addDocument("its dark out today", "negative");
classifier.addDocument("today was bad", "negative");
classifier.calculateLogFrequencies();
console.log(classifier.classify('hello you are great'));
/*
{
classification: { label: 'POSITIVE', value: -6.238324625039508 },
labels: { POSITIVE: -6.238324625039508, NEGATIVE: -6.238324625039508 }
}
*/
```
