Biography: Jungseul Ok is an assistant professor in the Department of Computer Science and Engineering at POSTECH, Pohang, South Korea. He completed Ph.D program in School of Electrical Engineering at Korea Advanced Institute of Science and Technology (KAIST), South Korea, under the supervision of Prof. Yung Yi and Prof. Jinwoo Shin. After graduation, he worked with Prof. Alexandre Proutiere and Prof. Sewoong Oh as a postdoctoral researcher, respectively, in School of Electrical Engineering at KTH, Stockholm, Sweden, and Paul G. Allen School of Computer Science & Engineering, University of Washington, WA, US.

Research Topic: His research focus is understanding and improving practical systems based on theoretical model and analysis, where the systems of particular interest associate with graphical representations, e.g., Markov decision process, neural/wireless/social networks, and crowdsourcing system. Here are some keywords:

• * Reinforcement Learning – Markov decision process, multi-armed bandit, structured reinforcement learning
• * Learning in Graphical Model – crowdsourced classification, belief propagation, correlation decay
• * Deep neural network – algorithmic regularization, deep reinforcement learning
• * Social network – strategic diffusion, influence maximization, Ising model, hitting time analysis
• * Wireless Network – rate adaptation for 802.11n/ac, network virtualization
