Evolutionary algorithms play a significant role as search techniques for handling complex problems in many fields such as artificial intelligence and engineering. The advantage of evolutionary algorithms is their ability to solve and quasi-optimize problems with non-linear, high-dimensional, multi-modal, and discontinuous character. These algorithms have the ability to explore large spaces, without demanding the use of derivatives of the objective functions, such as by gradient-based training methods. Their principles are based on the search for a population of solutions, where tuning is done using mechanisms similar to biological recombination.

In order to support advanced vehicular Internet-of-Vehicles (IoV) applications, information exchanges among different vehicles are required to find efficient solutions for catering to different application requirements in complex and dynamic vehicular environments. Federated learning (FL), which is a type of distributed learning technology, has been attracting great interest in recent years as it performs knowledge exchange among different network entities without a violation of user privacy. This talk will focus on networking technologies for supporting FL in vehicular environments in order to facilitate emerging IoV applications.

Cyber-Physical System and Digital Twin have been discussed in various research fields until now. In order to simulate a real-world phenomenon in the cyber world, we often have to extract features and structures based on graph theory and topology. Therefore, we proposed the concept of topological twin. The aim of topological twin is to (1) extract topological structures hidden implicitly in the real world, (2) reproduce them explicitly in the cyber world, and (3) simulate and analyze the real world in the cyber world. Furthermore, Cyber-Physical-Social Systems (CPSS) have been discussed based on the integration of information, intelligence, communication, and robot technologies. Basically, we need a multi-scopic approach to simulate and analyze the interaction in these three worlds, because we must deal with qualitatively different big data simultaneously. For example, we can discuss a phenomenon from three different levels of macro-, meso-, and micro- scopic simulations. In the microscopic simulation, we can deal with the dynamics inside objects and human mental and internal states. In the macroscopic simulation, we can deal with spatiotemporal qualitative relationships and interactions between objects and humans without dynamics. Furthermore, we can deal with a mesoscopic simulation based on the microscopic bottom-up construction and macroscopic top-down constrain. In this talk, we discuss a multi-scopic simulation to discuss human-robot interactions. First, we introduce various types of topological mapping methods, unsupervised learning methods, and graph-based methods. Next, we discuss how to apply topological mapping methods in the multi-scopic simulation for human-robot interactions. Finally, we discuss the effectiveness of the proposed method through several simulation results.
