DeepAbstract: Neural Network Abstraction for Accelerating Verification

no code implementations24 Jun 2020 Pranav Ashok, Vahid Hashemi, Jan Křetínský, Stefanie Mohr

While abstraction is a classic tool of verification to scale it up, it is not used very often for verifying neural networks.

Towards Safety Verification of Direct Perception Neural Networks

1 code implementation9 Apr 2019 Chih-Hong Cheng, Chung-Hao Huang, Thomas Brunner, Vahid Hashemi

We study the problem of safety verification of direct perception neural networks, where camera images are used as inputs to produce high-level features for autonomous vehicles to make control decisions.
