Event Weekly OSI Lab Seminar Short summary In this seminar, I will talk about the influential paper “How Powerful are Graph Neural Networks?” (Xu et al., ICLR'19 oral). Abstract (taken directly from the paper)

Event OSI Lab Conference Week (NeurIPS 2020) Short summary In this seminar titled Topics not covered by anyone… (kind of), I will talk about 4 NeurIPS 2020 papers (all of which are theory-heavy) that I thought were interesting, whose topics were not covered by anyone in OSI Lab.

A novel problem setting where heterogeneous multi-agent bandits collaborate over a network to minimize their group regret. To deal with the high communication complexity of the classic flooding protocol combined with UCB, a new network protocol called Flooding with Absorption (FwA) is proposed. Theoretical and empirical analyses are provded for flooding and FwA, showing the efficacy of our proposed FwA.
