Optimal Regret with Limited Adaptivity for Generalized Linear Contextual Bandits

1 code implementation10 Apr 2024 Ayush Sawarni, Nirjhar Das, Siddharth Barman, Gaurav Sinha

For our batch learning algorithm B-GLinCB, with $\Omega\left( \log{\log T} \right)$ batches, the regret scales as $\tilde{O}(\sqrt{T})$.

Learning Good Interventions in Causal Graphs via Covering

no code implementations8 May 2023 Ayush Sawarni, Rahul Madhavan, Gaurav Sinha, Siddharth Barman

We study the causal bandit problem that entails identifying a near-optimal intervention from a specified set $A$ of (possibly non-atomic) interventions over a given causal graph.

Fairness and Welfare Quantification for Regret in Multi-Armed Bandits

no code implementations27 May 2022 Siddharth Barman, Arindam Khan, Arnab Maiti, Ayush Sawarni

Since NSW is known to satisfy fairness axioms, our approach complements the utilitarian considerations of average (cumulative) regret, wherein the algorithm is evaluated via the arithmetic mean of its expected rewards.
