Machine Learning. The Science of Selection under Uncertainty

Yevgeny Seldin

Learning, whether natural or artificial, is a process of selection. It starts with a set of candidate options and selects the more successful ones. In the case of machine learning…

Recursive PAC-Bayes: A Frequentist Approach to Sequential Prior Updates with No Information Loss

Yi-Shan Wu, Yijie Zhang, Badr-Eddine Chérief-Abdellatif +1

PAC-Bayesian analysis is a frequentist framework for incorporating prior knowledge into learning. It was inspired by Bayesian learning, which allows sequential data processing and…

A Best-of-both-worlds Algorithm for Bandits with Delayed Feedback with Robustness to Excessive Delays

Saeed Masoudian, Julian Zimmert, Yevgeny Seldin

We propose a new best-of-both-worlds algorithm for bandits with variably delayed feedback. In contrast to prior work, which required prior knowledge of the maximal delay $d_{\mathr…

Delayed Bandits: When Do Intermediate Observations Help?

Emmanuel Esposito, Saeed Masoudian, Hao Qiu +3

We study a -armed bandit with delayed feedback and intermediate observations. We consider a model where intermediate observations have a form of a finite state, which is observe…

A Best-of-Both-Worlds Algorithm for Bandits with Delayed Feedback

Saeed Masoudian, Julian Zimmert, Yevgeny Seldin

We present a modified tuning of the algorithm of Zimmert and Seldin [2020] for adversarial multiarmed bandits with delayed feedback, which in addition to the minimax optimal advers…

Split-kl and PAC-Bayes-split-kl Inequalities for Ternary Random Variables

Yi-Shan Wu, Yevgeny Seldin

We present a new concentration of measure inequality for sums of independent bounded random variables, which we name a split-kl inequality. The inequality is particularly well-suit…
