FARe: Fault-Aware GNN Training on ReRAM-based PIM Accelerators

no code implementations19 Jan 2024 Pratyush Dhingra, Chukwufumnanya Ogbogu, Biresh Kumar Joardar, Janardhan Rao Doppa, Ananth Kalyanaraman, Partha Pratim Pande

Experimental results demonstrate that FARe framework can restore GNN test accuracy by 47. 6% on faulty ReRAM hardware with a ~1% timing overhead compared to the fault-free counterpart.

Attention-based Models for Snow-Water Equivalent Prediction

1 code implementation3 Nov 2023 Krishu K. Thapa, Bhupinderjeet Singh, Supriya Savalkar, Alan Fern, Kirti Rajagopalan, Ananth Kalyanaraman

Our hypothesis is that attention has a unique ability to capture and exploit correlations that may exist across locations or the temporal spectrum (or both).

Interesting Paths in the Mapper

1 code implementation29 Dec 2017 Ananth Kalyanaraman, Methun Kamruzzaman, Bala Krishnamoorthy

For the special case when G is a directed acyclic graph (DAG), we show that Max-IP can be solved in polynomial time - in O(mnd_i) where d_i is the maximum indegree of a vertex in G. In the more general problem IP, the goal is to find a collection of edge-disjoint interesting paths such that the overall sum of their interestingness scores is maximized.

Hyppo-X: A Scalable Exploratory Framework for Analyzing Complex Phenomics Data

1 code implementation14 Jul 2017 Methun Kamruzzaman, Ananth Kalyanaraman, Bala Krishnamoorthy, Stefan Hey, Patrick Schnable

Notably, our approach shows how environmental factors could influence phenotypic behavior, and how that effect varies across different genotypes and different time scales.
