Watch Out for the Safety-Threatening Actors: Proactively Mitigating Safety Hazards

no code implementations2 Jun 2022 Saurabh Jha, Shengkun Cui, Zbigniew Kalbarczyk, Ravishankar K. Iyer

In this work, we propose a safety threat indicator (STI) using counterfactual reasoning to estimate the importance of each actor on the road with respect to its influence on the AV's safety.

Watch out for the risky actors: Assessing risk in dynamic environments for safe driving

no code implementations19 Oct 2021 Saurabh Jha, Yan Miao, Zbigniew Kalbarczyk, Ravishankar K. Iyer

Driving in a dynamic environment that consists of other actors is inherently a risky task as each actor influences the driving decision and may significantly limit the number of choices in terms of navigation and safety plan.

BayesPerf: Minimizing Performance Monitoring Errors Using Bayesian Statistics

no code implementations22 Feb 2021 Subho S. Banerjee, Saurabh Jha, Zbigniew T. Kalbarczyk, Ravishankar K. Iyer

Hardware performance counters (HPCs) that measure low-level architectural and microarchitectural events provide dynamic contextual information about the state of the system.

Inductive-bias-driven Reinforcement Learning For Efficient Schedules in Heterogeneous Clusters

no code implementations4 Sep 2019 Subho S. Banerjee, Saurabh Jha, Zbigniew T. Kalbarczyk, Ravishankar K. Iyer

The problem of scheduling of workloads onto heterogeneous processors (e. g., CPUs, GPUs, FPGAs) is of fundamental importance in modern data centers.

Exploiting Data Parallelism in the yConvex Hypergraph Algorithm for Image Representation using GPGPUs

no code implementations23 Jun 2013 Saurabh Jha, Tejaswi Agarwal, B. Rajesh Kanna

To define and identify a region-of-interest (ROI) in a digital image, the shape descriptor of the ROI has to be described in terms of its boundary characteristics.

P-HGRMS: A Parallel Hypergraph Based Root Mean Square Algorithm for Image Denoising

no code implementations23 Jun 2013 Tejaswi Agarwal, Saurabh Jha, B. Rajesh Kanna

This paper presents a parallel Salt and Pepper (SP) noise removal algorithm in a grey level digital image based on the Hypergraph Based Root Mean Square (HGRMS) approach.
