BERN-NN: Tight Bound Propagation For Neural Networks Using Bernstein Polynomial Interval Arithmetic

no code implementations22 Nov 2022 Wael Fatnassi, Haitham Khedr, Valen Yamamoto, Yasser Shoukry

Bernstein polynomials enjoy several interesting properties that allow BERN-NN to obtain tighter bounds compared to those relying on linear and convex approximations.

Provably Safe Model-Based Meta Reinforcement Learning: An Abstraction-Based Approach

no code implementations3 Sep 2021 Xiaowu Sun, Wael Fatnassi, Ulices Santa Cruz, Yasser Shoukry

While conventional reinforcement learning focuses on designing agents that can perform one task, meta-learning aims, instead, to solve the problem of designing agents that can generalize to different tasks (e. g., environments, obstacles, and goals) that were not considered during the design or the training of these agents.

PolyAR: A Highly Parallelizable Solver For Polynomial Inequality Constraints Using Convex Abstraction Refinement

no code implementations12 Jan 2021 Wael Fatnassi, Yasser Shoukry

Third, it allows for a highly parallelizable usage of off-the-shelf solvers to analyze the regions in which the convex relaxation failed to provide solutions.
