Semantic-Based Neural Network Repair

no code implementations12 Jun 2023 Richard Schumi, Jun Sun

The results show that we are able to repair 100% of a set of randomly generated neural networks (which are produced with an existing AI framework testing approach) effectively and efficiently (with an average repair time of 21. 08s) and 93. 75% of a collection of real neural network bugs (with an average time of 3min 40s).

The Security Reference Architecture for Blockchains: Towards a Standardized Model for Studying Vulnerabilities, Threats, and Defenses

no code implementations22 Oct 2019 Ivan Homoliak, Sarad Venugopalan, Qingze Hum, Daniel Reijsbergen, Richard Schumi, Pawel Szalachowski

We propose the security reference architecture (SRA) for blockchains, which adopts a stacked model (similar to the ISO/OSI) describing the nature and hierarchy of various security and privacy aspects.
