ForestPosterior

sealed interface ForestPosterior : RegressionPosterior<ForestRegressionResult> (source)

TreePosterior family ported to forests: every leaf snapshot the query routes to is merged into a single weighted-variance result, then scored with the tree-posterior semantics. Same options, applied to the ensembled leaf.

Functions

evaluate

abstract fun evaluate(snapshot: ForestRegressionResult, x: VectorView, rng: Random, exploration: Double = 1.0): Double

Score a query point x under the regression snapshot. exploration controls the posterior-variance scale (Thompson) or the UCB width (LinUcb-style); 0.0 collapses to the point estimate.
