DNNShield: Dynamic Randomized Model Sparsification, A Defense Against Adversarial Machine Learning

no code implementations31 Jul 2022 Mohammad Hossein Samavatian, Saikat Majumdar, Kristin Barber, Radu Teodorescu

DNNs are known to be vulnerable to so-called adversarial attacks that manipulate inputs to cause incorrect results that can be beneficial to an attacker or damaging to the victim.

Using Undervolting as an On-Device Defense Against Adversarial Machine Learning Attacks

no code implementations20 Jul 2021 Saikat Majumdar, Mohammad Hossein Samavatian, Kristin Barber, Radu Teodorescu

These attacks make small imperceptible modifications to inputs that are sufficient to induce the DNNs to produce the wrong classification.

HASI: Hardware-Accelerated Stochastic Inference, A Defense Against Adversarial Machine Learning Attacks

no code implementations9 Jun 2021 Mohammad Hossein Samavatian, Saikat Majumdar, Kristin Barber, Radu Teodorescu

This paper presents HASI, a hardware-accelerated defense that uses a process we call stochastic inference to detect adversarial inputs.

Accident Risk Prediction based on Heterogeneous Sparse Data: New Dataset and Insights

11 code implementations19 Sep 2019 Sobhan Moosavi, Mohammad Hossein Samavatian, Srinivasan Parthasarathy, Radu Teodorescu, Rajiv Ramnath

Further, we have shown the impact of traffic information, time, and points-of-interest data for real-time accident prediction.

RNNFast: An Accelerator for Recurrent Neural Networks Using Domain Wall Memory

no code implementations7 Nov 2018 Mohammad Hossein Samavatian, Anys Bacha, Li Zhou, Radu Teodorescu

At the same time, the sequential nature of input/weight processing of RNNs mitigates one of the downsides of DWM, which is the linear (rather than constant) data access time. RNNFast is very efficient and highly scalable, with flexible mapping of logical neurons to RNN hardware blocks.
