An Effective Baseline for Robustness to Distributional Shift

1 code implementation15 May 2021 Sunil Thulasidasan, Sushil Thapa, Sayera Dhaubhadel, Gopinath Chennupati, Tanmoy Bhattacharya, Jeff Bilmes

In this work we present a simple, but highly effective approach to deal with out-of-distribution detection that uses the principle of abstention: when encountering a sample from an unseen class, the desired behavior is to abstain from predicting.

Autonomous Control of a Particle Accelerator using Deep Reinforcement Learning

no code implementations16 Oct 2020 Xiaoying Pang, Sunil Thulasidasan, Larry Rybarcyk

We describe an approach to learning optimal control policies for a large, linear particle accelerator using deep reinforcement learning coupled with a high-fidelity physics engine.

Combating Label Noise in Deep Learning Using Abstention

2 code implementations27 May 2019 Sunil Thulasidasan, Tanmoy Bhattacharya, Jeff Bilmes, Gopinath Chennupati, Jamal Mohd-Yusof

In the case of unstructured (arbitrary) label noise, abstention during training enables the DAC to be used as an effective data cleaner by identifying samples that are likely to have label noise.

Knows When it Doesn’t Know: Deep Abstaining Classifiers

no code implementations ICLR 2019 Sunil Thulasidasan, Tanmoy Bhattacharya, Jeffrey Bilmes, Gopinath Chennupati, Jamal Mohd-Yusof

We introduce the deep abstaining classifier -- a deep neural network trained with a novel loss function that provides an abstention option during training.

Efficient Distributed Semi-Supervised Learning using Stochastic Regularization over Affinity Graphs

no code implementations15 Dec 2016 Sunil Thulasidasan, Jeffrey Bilmes, Garrett Kenyon

We describe a computationally efficient, stochastic graph-regularization technique that can be utilized for the semi-supervised training of deep neural networks in a parallel or distributed setting.

Semi-Supervised Phone Classification using Deep Neural Networks and Stochastic Graph-Based Entropic Regularization

no code implementations15 Dec 2016 Sunil Thulasidasan, Jeffrey Bilmes

We describe a graph-based semi-supervised learning framework in the context of deep neural networks that uses a graph-based entropic regularizer to favor smooth solutions over a graph induced by the data.
