Yasin AbbasiYadkoriVinAI Hanoi, Vietnam Gmail: "yasin dot abbasi" 
I am a researcher at VinAI. Prior to that I was a researcher at Adobe, and before that I was a postdoctoral fellow at Queensland University of Technology with Peter Bartlett. I completed my PhD at University of Alberta under the supervision of Csaba Szepesvari. Research interests: Artificial intelligence, machine learning, sequential decision problems, sampling and optimization
