`DirichletProcessOn` — The keyed Dirichlet process distribution

Usage

DirichletProcessOn(keys: Set<a>, alpha: Double, dist: Distribution<b>) → Distribution<Map<a,b>>

Type constraints: Ord<a>

Arguments

keys:: The keys identifying the samples
alpha:: The concentration parameter controlling how often new values are drawn
dist:: The base distribution on shared values

Description

Draw one exchangeable Dirichlet process value for each supplied key. Entries assigned to the same cluster share one value drawn from dist.

Examples

~DirichletProcessOn({3,1,4}, 1, Normal(0,1))
