GAN-MPC: Training Model Predictive Controllers with Parameterized Cost Functions using Demonstrations from Non-identical Experts

1 code implementation30 May 2023 Returaj Burnwal, Anirban Santara, Nirav P. Bhatt, Balaraman Ravindran, Gaurav Aggarwal

We propose a novel approach that uses a generative adversarial network (GAN) to minimize the Jensen-Shannon divergence between the state-trajectory distributions of the demonstrator and the imitator.

On Learning to Rank Long Sequences with Contextual Bandits

no code implementations7 Jun 2021 Anirban Santara, Claudio Gentile, Gaurav Aggarwal, Shuai Li

Motivated by problems of learning to rank long item sequences, we introduce a variant of the cascading bandit model that considers flexible length sequences with varying rewards and losses.

ExTra: Transfer-guided Exploration

no code implementations27 Jun 2019 Anirban Santara, Rishabh Madan, Balaraman Ravindran, Pabitra Mitra

Given an optimal policy in a related task-environment, we show that its bisimulation distance from the current task-environment gives a lower bound on the optimal advantage of state-action pairs in the current task-environment.

PUNCH: Positive UNlabelled Classification based information retrieval in Hyperspectral images

1 code implementation Submitted to ACMMM-2019 2019 Anirban Santara, Jayeeta Datta, Sourav Sarkar, Ankur Garg, Kirti Padia, Pabitra Mitra

In order to address these issues, we aim to develop a framework for material-agnostic information retrieval in hyperspectral images based on Positive-Unlabelled (PU) classification.
