Evaluation of STT-MRAM as a Scratchpad for Training in ML Accelerators

no code implementations3 Aug 2023 Sourjya Roy, Cheng Wang, Anand Raghunathan

We devised a cross-layer simulation framework to evaluate the effectiveness of STT-MRAM as a scratchpad replacing SRAM in a systolic-array-based DNN accelerator.

Pruning Filters while Training for Efficiently Optimizing Deep Learning Networks

no code implementations5 Mar 2020 Sourjya Roy, Priyadarshini Panda, Gopalakrishnan Srinivasan, Anand Raghunathan

Our results for VGG-16 trained on CIFAR10 shows that L1 normalization provides the best performance among all the techniques explored in this work with less than 1% drop in accuracy after pruning 80% of the filters compared to the original network.

TxSim:Modeling Training of Deep Neural Networks on Resistive Crossbar Systems

no code implementations25 Feb 2020 Sourjya Roy, Shrihari Sridharan, Shubham Jain, Anand Raghunathan

To address this challenge, there is a need for tools that can model the functional impact of non-idealities on DNN training and inference.

Gradual Channel Pruning while Training using Feature Relevance Scores for Convolutional Neural Networks

1 code implementation23 Feb 2020 Sai Aparna Aketi, Sourjya Roy, Anand Raghunathan, Kaushik Roy

To address all the above issues, we present a simple-yet-effective gradual channel pruning while training methodology using a novel data-driven metric referred to as feature relevance score.
