讲座摘要

Artificial Intelligence (AI) aims at creating a computerised system capable of acquiring and applying knowledge and skills as a result of experience. Being able to perceive the world and subsequently interacting with it are the two pillars of intelligence that should be maintained in any AI system.

In scientific research, it is widely accepted that the former corresponds to pattern recognition, while the latter is related to machine decision making. With the decades of efforts to supervised and unsupervised learning, many pattern recognition problems have been well explored and a lot of successful stories can be found ranging from speech recognition and machine translation to visual object detection and recognition. By contrast, machine decision making is still at its infant stage due to lack of understanding of its intrinsic complexity of the decision space, and more research effort is required to drive progress in this field forward.

In addition, multi-agent learning arises in a variety of domains where intelligent agents interact not only with the (unknown) environment but also with each other. It has an increasing number of applications ranging from controlling a group of autonomous vehicles/robots/drones to coordinating collaborative bots in production lines, optimising distributed sensor networks/traffic, and machine bidding in competitive e-commerce, search and information retrieval and financial markets.

In this talk, I shall provide an up-to-date introduction on the technique and algorithms of machine decision making and multi-agent AI, with a focus on competition, collaboration, and communications among intelligent agents. The studies in both game theory and machine learning will be examined in a unified treatment. I shall also sample our recent work on the subject including mean-field multiagent reinforcement learning, generative adversarial nets, hierarchical reinforcement learning and their applications in information retrieval and search.
