Usage

import NGramModel from 'ngram-model';

// create a 4-gram model
const NGram = new NGramModel(4);

// pass the model a long text to learn
NGram.train('SOME LONG TRAINER TEXT');

// train more...
NGram.train('EVEN MORE TRAINING');

// guess next 3 tokens, based on the experience from training
NGram.guess('I need a', 3);

// guess as many next tokens as possible, based on the experience from training
NGram.guess('She is');

// guess as many next tokens as possible, the starting text is up to what the 
// model has seen on training texts
NGram.guess();

new NGramModel(N)

• N number N in N-gram model

Creates an N-Gram model

NGram.train(text)

• text <string> text to train the model

Trains the model using a training text

NGram.guess([starterText, tokenCount])

• starterText <string> starter text to be used for guessing next tokens
• tokenCount <number> maximum number of tokens to be guessed
• Returns: <string[]> array of guessed tokens

Guesses next tokens of the sequence based on experience from trainings (will throw error if no training is done before)
