DynaMarks: Defending Against Deep Learning Model Extraction Using Dynamic Watermarking

no code implementations27 Jul 2022 Abhishek Chakraborty, Daniel Xing, Yuntao Liu, Ankur Srivastava

The functionality of a deep learning (DL) model can be stolen via model extraction where an attacker obtains a surrogate model by utilizing the responses from a prediction API of the original model.

In-situ Stochastic Training of MTJ Crossbar based Neural Networks

no code implementations24 Jun 2018 Ankit Mondal, Ankur Srivastava

Owing to high device density, scalability and non-volatility, Magnetic Tunnel Junction-based crossbars have garnered significant interest for implementing the weights of an artificial neural network.

Neural Trojans

no code implementations3 Oct 2017 Yuntao Liu, Yang Xie, Ankur Srivastava

In many cases, it is more practical to use a neural network intellectual property (IP) that an IP vendor has already trained.

Power Optimizations in MTJ-based Neural Networks through Stochastic Computing

no code implementations17 Aug 2017 Ankit Mondal, Ankur Srivastava

In this work, we propose an energy-efficient use of MTJs, which exhibit probabilistic switching behavior, as Stochastic Number Generators (SNGs), which forms the basis of our NN implementation in the SC domain.
