Fixed-Budget Best-Arm Identification with Heterogeneous Reward Variances
Anusha Lalitha, Kousha Kalantari, Yifei Ma +2
We study the problem of best-arm identification (BAI) in the fixed-budget setting with heterogeneous reward variances. We propose two variance-adaptive BAI algorithms for this sett…
Partner-Aware Algorithms in Decentralized Cooperative Bandit Teams
Erdem Bıyık, Anusha Lalitha, Rajarshi Saha +2
When humans collaborate with each other, they often make decisions by observing others and considering the consequences that their actions may have on the entire team, instead of g…
Causal Posterior Matching and its Applications
Anusha Lalitha, Anatoly Khina, Tara Javidi
We consider the problem of communication over the binary symmetric channel with feedback, where the information sequence is made available in a causal, possibly random, fashion. We…
On Error Exponents of Almost-Fixed-Length Channel Codes and Hypothesis Tests
Anusha Lalitha, Tara Javidi
We examine a new class of channel coding strategies, and hypothesis tests referred to as almost-fixed-length strategies that have little flexibility in the stopping time over fixed…
Bayesian Algorithms for Decentralized Stochastic Bandits
Anusha Lalitha, Andrea Goldsmith
We study a decentralized cooperative multi-agent multi-armed bandit problem with arms and agents connected over a network. In our model, each arm's reward distribution is s…
Decentralized Bayesian Learning over Graphs
Anusha Lalitha, Xinghan Wang, Osman Kilinc +3
We propose a decentralized learning algorithm over a general social network. The algorithm leaves the training data distributed on the mobile devices while utilizing a peer to peer…
