Efficient One Sided Kolmogorov Approximation

no code implementations14 Jul 2022 Liat Cohen, Tal Grinshpoun, Gera Weiss

We present an efficient algorithm that, given a discrete random variable $X$ and a number $m$, computes a random variable whose support is of size at most $m$ and whose Kolmogorov distance from $X$ is minimal, also for the one-sided Kolmogorov approximation.

An optimal approximation of discrete random variables with respect to the Kolmogorov distance

no code implementations19 May 2018 Liat Cohen, Dror Fried, Gera Weiss

We present an algorithm that takes a discrete random variable $X$ and a number $m$ and computes a random variable whose support (set of possible outcomes) is of size at most $m$ and whose Kolmogorov distance from $X$ is minimal.

Estimating the Probability of Meeting a Deadline in Hierarchical Plans

no code implementations4 Mar 2015 Liat Cohen, Solomon Eyal Shimony, Gera Weiss

For the proposed approximation algorithm, we establish formal approximation bounds and show that the time and memory complexities grow polynomially with the required accuracy, the number of nodes in the plan, and with the size of the support of the random variables that represent the durations of the primitive tasks.
