库里和霍华德会见博雷尔

Curry and Howard Meet Borel

Melissa Antonelli, Ugo Dal Lago, Paolo Pistone

摘要:

我们表明,计数命题逻辑的直观版本对应,在咖喱和霍华德的意义上,一个表达型系统的概率性事件的aldida演算,车辆演算,其中调用的名称和调用的离散随机函数程序的值评估可以模拟。值得注意的是,证明(分别是类型)不仅保证有效性(分别是终止性)成立,而且还揭示了潜在的概率。最后,我们表明,通过赋予类型系统的交集算子,得到一个系统,精确地捕捉概率行为的pendoda条款。

英文摘要:

We show that an intuitionistic version of counting propositional logic corresponds, in the sense of Curry and Howard, to an expressive type system for the probabilistic event lambda-calculus, a vehicle calculus in which both call-by-name and call-by-value evaluation of discrete randomized functional programs can be simulated. Remarkably, proofs (respectively, types) do not only guarantee that validity (respectively, termination) holds, but also reveal the underlying probability. We finally show that by endowing the type system with an intersection operator, one obtains a system precisely capturing the probabilistic behavior of lambda-terms.
