Crate gen_rs

gen_rs is a a library for general-purpose, low-level probabilistic modeling and inference. Modeling and inference are separated by a trait interface, called GenFn.

Any function that implements GenFn (representing a Bayesian model) can use and compose any inference procedure in the standard inference library.

Modules

• address
  Utilities for parsing addresses (special keys used in the Trie data structure).
• gfi
  Definition of the Generative Function Interface (GFI).
• inference
  Standard inference library.
• modeling
  Distributions and a modeling DSL built on Tries.
• trie
  Implementations of the Trie data structure, used extensively in modeling::triefn.

Constants

• GLOBAL_RNG
  Forked PRNG, accessible as a static crate-level thread-local constant. (Use like GLOBAL_RNG.with_borrow_mut(|rng| { ... })).

Functions

• logsumexp
  For an input vector of [x1, ..., xn], return log(exp(x1) + ... + exp(xn)).
