InitialBigramPartitioner

class InitialBigramPartitioner[WordType] extends Partitioner

Partitions each ngram by hashing on its first two words (first as in farthest away from the current word), then mod by numPartitions.

Useful for grouping ngrams that share the first two words in context. An example usage is the StupidBackoffEstimator.

WordType

type of each word (e.g. Int or String)
