Optimal Design for Human Feedback

no code implementations22 Apr 2024 Subhojyoti Mukherjee, Anusha Lalitha, Kousha Kalantari, Aniket Deshmukh, Ge Liu, Yifei Ma, Branislav Kveton

Learning of preference models from human feedback has been central to recent advances in artificial intelligence.

Fixed-Budget Best-Arm Identification with Heterogeneous Reward Variances

no code implementations13 Jun 2023 Anusha Lalitha, Kousha Kalantari, Yifei Ma, Anoop Deoras, Branislav Kveton

Our algorithms rely on non-uniform budget allocations among the arms where the arms with higher reward variances are pulled more often than those with lower variances.

Partner-Aware Algorithms in Decentralized Cooperative Bandit Teams

no code implementations2 Oct 2021 Erdem Biyik, Anusha Lalitha, Rajarshi Saha, Andrea Goldsmith, Dorsa Sadigh

Our results show that the proposed partner-aware strategy outperforms other known methods, and our human subject studies suggest humans prefer to collaborate with AI agents implementing our partner-aware strategy.

Bayesian Algorithms for Decentralized Stochastic Bandits

no code implementations20 Oct 2020 Anusha Lalitha, Andrea Goldsmith

Specifically, we study an information assimilation algorithm that can be combined with existing Bayesian algorithms, and using this, we propose a decentralized Thompson Sampling algorithm and decentralized Bayes-UCB algorithm.

Decentralized Bayesian Learning over Graphs

no code implementations24 May 2019 Anusha Lalitha, Xinghan Wang, Osman Kilinc, Yongxi Lu, Tara Javidi, Farinaz Koushanfar

The proposed algorithm can be viewed as a Bayesian and peer-to-peer variant of federated learning in which each agent keeps a "posterior probability distribution" over a global model parameters.

Peer-to-peer Federated Learning on Graphs

no code implementations31 Jan 2019 Anusha Lalitha, Osman Cihan Kilinc, Tara Javidi, Farinaz Koushanfar

We consider the problem of training a machine learning model over a network of nodes in a fully decentralized framework.

Automatic Grammar Augmentation for Robust Voice Command Recognition

no code implementations14 Nov 2018 Yang Yang, Anusha Lalitha, Jinwon Lee, Chris Lott

For a given grammar set, a set of potential grammar expressions (candidate set) for augmentation is constructed from an AM-specific statistical pronunciation dictionary that captures the consistent patterns and errors in the decoding of AM induced by variations in pronunciation, pitch, tempo, accent, ambiguous spellings, and noise conditions.
