Cambria: Resource Abstraction for Parametrized Algebraic Effects and Handlers
Jack Liell-Cock, Sam Staton
The algebraic effects and handlers paradigm separates the concerns of the interface and implementation of computational effects in programming languages. We present Cambria, a lang…
Imprecise Probabilistic Programming, Precisely: Credal Sets via Graded Monads, BDDs, and Semiring-Parametric Inference (Functional Pearl)
Jack Liell-Cock, Sam Staton
Imprecise probability generalizes standard probability theory by replacing a single distribution with a convex set of possible distributions. We show that this generalization requi…
An Equational Axiomatization of Dynamic Threads via Algebraic Effects: Presheaves on Finite Relations, Labelled Posets, and Parameterized Algebraic Theories
Ohad Kammar, Jack Liell-Cock, Sam Lindley +2
We use the theory of algebraic effects to give a complete equational axiomatization for dynamic threads. Our method is based on parameterized algebraic theories, which give a concr…
The Relative Monadic Metalanguage
Jack Liell-Cock, Zev Shirazi, Sam Staton
Relative monads provide a controlled view of computation. We generalise the monadic metalanguage to a relative setting and give a complete semantics with strong relative monads. Ad…
