On Abruptly-Changing and Slowly-Varying Multiarmed Bandit Problems

We study the non-stationary stochastic multiarmed bandit (MAB) problem and propose two generic algorithms, namely, the limited memory deterministic sequencing of exploration and exploitation (LM-DSEE) and the SlidingWindow Upper Confidence Bound# (SW-UCB#). We rigorously analyze these algorithms in abruptly-changing and slowlyvarying environments and characterize their performance. We show that...

Recognizing Abruptly Changing Facial Expressions fromTime - sequential Face

This paper proposes a method that can spot and recognize each facial expression from time-sequential images that contain multiple facial expressions that could abruptly change from one expression to another expression. Previously, the authors have proposed an HMM (Hidden Markov Models) based method for recognizing a spotted facial expression. In this paper, to HMM, we add states corresponding t...

The Arctic is changing

Seafood from a changing Arctic

We review current knowledge about climate change impacts on Arctic seafood production. Large-scale changes in the Arctic marine food web can be expected for the next 40-100 years. Possible future trajectories under climate change for Arctic capture fisheries anticipate the movement of aquatic species into new waters and changed the dynamics of existing species. Negative consequences are expecte...
