Abstract:

Due to the recent development of novel technologies such as Internet of Things (IoT), autonomous machines (e.g., driverless cars, or UAVs), and crowdsourcing systems, collaborative AI systems, or human-agent collectives (as called by some other researchers), in which humans and machines (or agents) have to perform some degree of cooperation with each other in order to achieve certain goals, are becoming a reality. In many cases, the required objectives of these collectives can be formalized as optimization problems. However, standard optimisation solution techniques fail to efficiently tackle these objectives, as they typically ignore the optimization constraints caused by the human factor.  For example, algorithms that require a sequence of iterative optimization steps (e.g., gradient descent) assume that the participating agent (or human) will follow the steps of the optimisation process, described by the algorithm. However, humans might get disengaged or unmotivated, and thus, might leave the process, or intentionally do not follow the instructions given by the algorithm. Another example comes from the potential miscommunication between humans and agents, typically caused by inefficient interaction interfaces. Finally, trust (e.g., is the human trustworthy?), privacy (e.g., how to protect the human’s privacy?), and security (e.g., how not to provide security wholes with humans typically to be the weakest chain) issues might occur during the process. Such new constraints introduce new challenges in solving optimization problems of human-agent collectives. Whereas some solutions have been proposed to tackle specific sub-problems with restricted settings, no effort has been made to date to investigate the problems of user motivation, privacy and security from a more fundamental and generic perspective, which is essential in order to fully understand these problems, and thus, to provide more efficient solutions to tackle them. In this talk, I will  discuss some research solutions within each abovementioned topic. In particular, I will mainly focus on the problem of having the human factor in optimization problems, a research area I have been working on with my collaborators from the University of Southampton, Nanyang Technical University, and University of Southern California.
