Online GentleAdaBoost -- Technical Report

Chapman Siu

We study the online variant of GentleAdaboost, where we combine a weak learner to a strong learner in an online fashion. We provide an approach to extend the batch approach to an o…

Regularize! Don't Mix: Multi-Agent Reinforcement Learning without Explicit Centralized Structures

Chapman Siu, Jason Traish, Richard Yi Da Xu

We propose using regularization for Multi-Agent Reinforcement Learning rather than learning explicit cooperative structures called {\em Multi-Agent Regularized Q-learning} (MARQ).…

Dual Behavior Regularized Reinforcement Learning

Chapman Siu, Jason Traish, Richard Yi Da Xu

Reinforcement learning has been shown to perform a range of complex tasks through interaction with an environment or collected leveraging experience. However, many of these approac…

Greedy UnMixing for Q-Learning in Multi-Agent Reinforcement Learning

Chapman Siu, Jason Traish, Richard Yi Da Xu

This paper introduces Greedy UnMix (GUM) for cooperative multi-agent reinforcement learning (MARL). Greedy UnMix aims to avoid scenarios where MARL methods fail due to overestimati…

Residual Networks Behave Like Boosting Algorithms

Chapman Siu

We show that Residual Networks (ResNet) is equivalent to boosting feature representation, without any modification to the underlying ResNet training algorithm. A regret bound based…

Diverse Online Feature Selection

Chapman Siu, Richard Yi Da Xu

Online feature selection has been an active research area in recent years. We propose a novel diverse online feature selection method based on Determinantal Point Processes (DPP).…
