"Uncertainty is a C# library that uses LINQ to let developers easily express probabilistic computations and then inference over those computations."
"This paper introduces Uncertain< T >, a new programming language abstraction for uncertain data. We implement a Bayesian network semantics for computation and conditionals that improves program correctness. The runtime uses sampling and hypothesis tests to evaluate computation and conditionals lazily and efficiently. We illustrate with sensor and machine learning applications that Uncertain improves expressiveness and accuracy.
Whereas previous probabilistic programming languages focus on experts, Uncertain< T > serves a wide range of developers. Experts still identify error distributions. However, both experts and application writers compute with distributions, improve estimates with domain knowledge, and ask questions with conditionals. The Uncertain< T > type system and operators encourage developers to expose and reason about uncertainty explicitly, controlling false positives and false negatives. These benefits make Uncertain< T > a compelling programming model for modern applications facing the challenge of uncertainty."
