Quote

My current research topics are:
• Tailor the Monte Carlo search to the problem being learned. For example for single player games a Nested Monte Carlo search might learn better than the standard PUCT search. Similarly for incomplete information problems PUCT might not be the best algorithm.
• Accelerate Alpha Zero type Deep Reinforcement Learning. The current algorithm requires huge computations. Finding ways to learn faster is important.
• Apply a combination of Monte Carlo search and Deep Learning to various
optimization problems.
• Explore various network architectures. For example residual networks enable to train deeper net-works faster and with better results. Layers such as Average Spatial Pooling improve much the quality of value networks. New network architectures may improve substantially the level of play.
