Computational integrity with a public random string from quasi-linear PCPs.

2016

A party executing a computation on behalf of others may benefit from misreporting its output. Cryptographic protocols that detect this can facilitate decentralized systems with stringent computational integrity requirements. For the computation’s result to be …

Characterizing and Taming Model Instability Across Edge Devices

2020 · arXiv (Cornell University)

The same machine learning model running on different edge devices may produce highly-divergent outputs on a nearly-identical input. Possible reasons for the divergence include differences in the device sensors, the device's signal processing hardware and …
