Slowly Changing Adversarial Bandit Algorithms are Efficient for Discounted MDPs

no code implementations18 May 2022 Ian A. Kash, Lev Reyzin, Zishun Yu

Reinforcement learning generalizes multi-armed bandit problems with additional difficulties of a longer planning horizon and unknown transition kernel.

A Unified Analysis of Dynamic Interactive Learning

no code implementations14 Apr 2022 Xing Gao, Thomas Maranzatto, Lev Reyzin

In this paper we investigate the problem of learning evolving concepts over a combinatorial structure.

Communication-Aware Collaborative Learning

no code implementations19 Dec 2020 Avrim Blum, Shelby Heinecke, Lev Reyzin

In this paper, we study collaborative PAC learning with the goal of reducing communication cost at essentially no penalty to the sample complexity.

On the Complexity of Learning from Label Proportions

no code implementations7 Apr 2020 Benjamin Fish, Lev Reyzin

In the problem of learning with label proportions, which we call LLP learning, the training data is unlabeled, and only the proportions of examples receiving each label are given.

Statistical Queries and Statistical Algorithms: Foundations and Applications

no code implementations1 Apr 2020 Lev Reyzin

We give a survey of the foundations of statistical queries and their many applications to other areas.

On Biased Random Walks, Corrupted Intervals, and Learning Under Adversarial Design

no code implementations30 Mar 2020 Daniel Berend, Aryeh Kontorovich, Lev Reyzin, Thomas Robinson

We tackle some fundamental problems in probability theory on corrupted random processes on the integer line.

On Learning a Hidden Directed Graph with Path Queries

no code implementations26 Feb 2020 Mano Vikash Janardhanan, Lev Reyzin

In this paper, we consider the problem of reconstructing a directed graph using path queries.

Sampling Without Compromising Accuracy in Adaptive Data Analysis

no code implementations28 Sep 2017 Benjamin Fish, Lev Reyzin, Benjamin I. P. Rubinstein

In this work, we study how to use sampling to speed up mechanisms for answering adaptive queries into datasets without reducing the accuracy of those mechanisms.

Data Stability in Clustering: A Closer Look

no code implementations12 Jul 2011 Shalev Ben-David, Lev Reyzin

Awasthi et al. (2010) consider center-based objectives, and Balcan and Liang (2011) analyze the $k$-median and min-sum objectives, giving efficient algorithms for instances resilient to certain constant multiplicative perturbations.

Non-Stochastic Bandit Slate Problems

no code implementations NeurIPS 2010 Satyen Kale, Lev Reyzin, Robert E. Schapire

We consider bandit problems, motivated by applications in online advertising and news story selection, in which the learner must repeatedly select a slate, that is, a subset of size s from K possible actions, and then receives rewards for just the selected actions.
