Contextual Bandits for adapting to changing User preferences over time

no code implementations21 Sep 2020 Dattaraj Rao

We explore details on contextual bandits, an extension to the traditional reinforcement learning (RL) problem and build a novel algorithm to solve this problem using an array of action-based learners.

Healthcare NER Models Using Language Model Pretraining

no code implementations23 Oct 2019 Amogh Kamat Tarcar, Aashis Tiwari, Vineet Naique Dhaimodker, Penjo Rebelo, Rahul Desai, Dattaraj Rao

Our solution uses a combination of Natural Language Processing (NLP) techniques and a web-based annotation tool to optimize the performance of a custom Named Entity Recognition (NER) [1] model trained on a limited amount of EHR training data.

Leveraging human Domain Knowledge to model an empirical Reward function for a Reinforcement Learning problem

no code implementations16 Sep 2019 Dattaraj Rao

This modeling of empirical human domain rules into a reward function for RL is the unique aspect of this paper.

Regional Priority Based Anomaly Detection using Autoencoders

no code implementations2 Apr 2018 Shruti Mittal, Dattaraj Rao

In the recent times, autoencoders, besides being used for compression, have been proven quite useful even for regenerating similar images or help in image denoising.

Face recognition for monitoring operator shift in railways

no code implementations5 Feb 2018 S. Ritika, Dattaraj Rao

If they exceed 8 hours of shift the railroads may be penalized for over-tiring their drivers.

Railway Track Specific Traffic Signal Selection Using Deep Learning

no code implementations17 Dec 2017 S. Ritika, Shruti Mittal, Dattaraj Rao

Using advanced image analysis and deep learning techniques, signals are detected in these camera images and a database of their locations is created.

Vision Based Railway Track Monitoring using Deep Learning

no code implementations17 Nov 2017 Shruti Mittal, Dattaraj Rao

Computer vision based methods have been explored in the past for detection of railway track defects, but full automation has always been a challenge because both traditional image processing methods and deep learning classifiers trained from scratch fail to generalize that well to infinite novel scenarios seen in the real world, given limited amount of labeled data.
