Dear all,
This Monday, October 21, we have Julien Zhou speaking in the Statistics and Machine Learning Thematic Seminar. Julien is a visiting PhD student from Inria and Criteo.

*Monday October 21*, 16h00-17h00 Hybrid, at the University of Amsterdam and Online Location: Korteweg-de Vries Institute for Mathematics, Science Park 907, Room F1.15 Directions: https://kdvi.uva.nl/contact/contact.html Online: https://uva-live.zoom.us/j/83485037604
*Submodular Optimization with Bandit feedbacks
*We address the online unconstrained submodular maximization problem (Online USM), in a setting with stochastic bandit feedback. In this framework, a decision-maker receives noisy rewards from a nonmonotone submodular function, taking values in a known bounded interval. We propose an Explore-then-Commit inspired approach satisfying logarithmic problem-dependent, 1/2-approximate regret, leveraging the inner structure of the reward.
