Jun-Kun Wang

I am a fourth year PhD student in CS at Georgia Tech. My advisor is Professor Jacob Abernethy. Before that, I was a research assistant at CSIE Department, National Taiwan University (NTU), where I worked with Prof. Shou-De Lin and also worked closely with Dr. Chi-Jen Lu at Academia Sinica. I am from Taiwan!

Fun fact 1: I like to run and enjoy long runs (especially along a river or bay). I run a lot!

Fun fact 2: I am always a top x% reviewer since NIPS/NeurIPS 2017 (x is the number that guarantees a registration of NeurIPS). Give me a paper, I can quickly provide a quite good review!

Reviwerer of NIPS/NeurIPS 2016,2017,2018,2019, of ICML 2017,2018,2019,2020, of COLT 2017,2018,2019,2020, of ALT 2017,2018,2019,2020.

Research

I am interested in machine learning and optimization. I like theoretical justification as well as real-world applications. Particularly, I am fascinated by sequential learning and decision making. But I am broadly interested in many topics in machine learning.
