Methods Documentation

classmethod train(data, minSupport=0.3, numPartitions=- 1)

Computes an FP-Growth model that contains frequent itemsets.

New in version 1.4.0.

Parameters

datapyspark.RDD

The input data set, each element contains a transaction.

minSupportfloat, optional

The minimal support level. (default: 0.3)

numPartitionsint, optional
