Core constructs of the DSL
val return : 'a -> 'a t
return x injects a value
x as a computation
If-then-else, mostly useful for monads featuring incremental computation. Allows to efficiently bind on a boolean computation.
module Infix : Intf.Infix with type 'a t := 'a t
sample dist builds a computation that samples from
dist. Note that
dist must be a pure computation.
samplei dist is similar to
sample except that
dist can be an impure computation (ie computing the distribution can involve sampling from other distributions).
map_score m f behaves similarly to
m except that the associated computation will be reweighted according to the result of evaluating
f on the value of
val map_log_score : 'a t -> ('a -> Log_space.t) -> 'a t
map_score excepts that a log-space likelihood is expected.
val score : float -> unit t
score s reweights the computation by
val log_score : Log_space.t -> unit t
log_score behaves as
score except that a log-space weight is expected.
module List_ops : Intf.Foldable with type 'a t = 'a list and type 'a m := 'a t
module Array_ops : Intf.Foldable with type 'a t = 'a array and type 'a m := 'a t
