Strategy

Instance Constructors

new Strategy(algo: Algo.Algo, impurity: Impurity, maxDepth: Int, maxBins: Int = 100, quantileCalculationStrategy: QuantileStrategy.QuantileStrategy = ..., categoricalFeaturesInfo: Map[Int, Int] = ..., maxMemoryInMB: Int = 128)

algo
classification or regression
impurity
criterion used for information gain calculation
maxDepth
maximum depth of the tree
maxBins
maximum number of bins used for splitting features
quantileCalculationStrategy
algorithm for calculating quantiles
categoricalFeaturesInfo
A map storing information about the categorical variables and the number of discrete values they take. For example, an entry (n -> k) implies the feature n is categorical with k categories 0, 1, 2, ... , k-1. It's important to note that features are zero-indexed.
maxMemoryInMB
maximum memory in MB allocated to histogram aggregation. Default value is 128 MB.
