Nearly Optimal Steiner Trees using Graph Neural Network Assisted Monte Carlo Tree Search

Reyan Ahmed, Mithun Ghosh, Kwang-Sung Jun +1

Graph neural networks are useful for learning problems, as well as for combinatorial and graph problems such as the Subgraph Isomorphism Problem and the Traveling Salesman Problem.…

Kullback-Leibler Maillard Sampling for Multi-armed Bandits with Bounded Rewards

Hao Qin, Kwang-Sung Jun, Chicheng Zhang

We study -armed bandit problems where the reward distributions of the arms are all supported on the interval. It has been a challenge to design regret-efficient randomiz…

Tighter PAC-Bayes Bounds Through Coin-Betting

Kyoungseok Jang, Kwang-Sung Jun, Ilja Kuzborskij +1

We consider the problem of estimating the mean of a sequence of random elements where is a fixed scalar function, ar…

Revisiting Simple Regret: Fast Rates for Returning a Good Arm

Yao Zhao, Connor James Stephens, Csaba Szepesvári +1

Simple regret is a natural and parameter-free performance criterion for pure exploration in multi-armed bandits yet is less popular than the probability of missing the best arm or…

PopArt: Efficient Sparse Regression and Experimental Design for Optimal Sparse Linear Bandits

Kyoungseok Jang, Chicheng Zhang, Kwang-Sung Jun

In sparse linear bandits, a learning agent sequentially selects an action and receive reward feedback, and the reward function depends linearly on a few coordinates of the covariat…

Norm-Agnostic Linear Bandits

Spencer, Gales, Sunder Sethuraman +1

Linear bandits have a wide variety of applications including recommendation systems yet they make one strong assumption: the algorithms must know an upper bound on the norm of…

An Experimental Design Approach for Regret Minimization in Logistic Bandits

Blake Mason, Kwang-Sung Jun, Lalit Jain

In this work we consider the problem of regret minimization for logistic bandits. The main challenge of logistic bandits is reducing the dependence on a potentially large problem d…

Improved Confidence Bounds for the Linear Logistic Model and Applications to Linear Bandits

Kwang-Sung Jun, Lalit Jain, Blake Mason +1

We propose improved fixed-design confidence bounds for the linear logistic model. Our bounds significantly improve upon the state-of-the-art bound by Li et al. (2017) via recent de…
