DEI TALKS | “Analyzing and Modeling Intelligent Systems Users’ Behavior in Digital Society” by Prof. Humberto Marques-Neto

Posted on

“Information systems are ever-increasingly intelligent and present in the daily lives of people and companies, facilitating and modifying the performance of various activities. In addition to handling each system’s intrinsic data, data from its users’ interactions can contribute to identifying, modeling, and analyzing people’s behavior patterns. The data analysis from the usage of web systems and mobile applications and, in particular, from online social networks such as Twitter, Facebook, WhatsApp, Instagram, and TikTok (obviously respecting the privacy of users) can contribute to the understanding of some dynamics and specific behaviors of human beings.

In this talk, I will present how our research group has done the characterization, analysis, and modeling of the behavior of users of intelligent information systems, more specifically, users of online social networks and information systems that make information available in open data portals, to induce the development of new software that use machine learning and artificial intelligent algorithms. The information systems user behavior, together with patterns of social interaction and human mobility in urban centers, in addition to subsidizing decisions and policies of government agencies and institutions responsible for urban planning, could foster and even target software developers interested in creating innovative software with the potential to improve people’s lives in a digital and connected society.”

“Analyzing and Modeling Intelligent Systems Users’ Behavior in Digital Society” will be presented January 25, at 14:00, room B006, moderated by Prof. Gil Gonçalves (DEI).

The thesis was co-supervised by Doutor Nuno Lau, Associate Professor at the University of Aveiro.

Abstract:
“This thesis studies the balance problem in game development, notably in two-player games. Specifically, we aim to study the viability of Artificial Intelligence (AI) as an assisting tool to fix game properties. We split our research into two paths: Power Balance, where the aim is to adjust game strategies, so they become effective as winning tools; Difficulty Balance, where the objective is to adjust game attributes on the fly so that weaker players or players at a disadvantage can compete with stronger players or players in advantage. Both domains require tuning the game, but they mainly differ in the timing and in their aim, one deals with the imbalance in game design, while the other deals with inequality in player skills. For Power Balance, our methodology was to define a full meta-game balance ecosystem based on the Pokémon video game franchise and develop an AI competition where the multiple associated tasks (battling, team prediction and assembly, and meta-game balance) are present and can be tested in a common ground. To balance the meta-game, we follow an adversarial model where team builders aim to narrow the use of optimal Pokémon while balancer agents aim to incentive the maximum of Pokémon as possible to be selected by team builders. This results in agents being able to play, build effective teams, and being able to tune the Pokémon roster over time. We discuss how our models can be extended to other video game domains. For Difficulty Balance, we propose a Multiplayer Dynamic Difficulty Adjustment framework where a Game Master (GM) agent is trained and embedded into a game, depending on the game state it will deploy handicap mechanisms. The training regime follows a specific pipeline. To generalize advantage situations, parameterized perturbations on the actions of a reference player are used to emulate several degrees of playing skill, and the advantage for each player is used to draw curves which are evaluated as a reward for the GM. This results in the GM being able to optimize game design criteria and create opportunities for the player behind to recover. We show there are suited AI tools for each task, and it is reasonable to think of power balance and difficulty as separate problems, where both can be automatically assisted and eased. Both further augment our overall comprehension of the automated game balance field.”

DEI TALKS| “Aprendizado colaborativo em redes neuronais artificiais” by Prof. Areolino de Almeida Neto

Posted on

“Any task that cannot be carried out by a single agent requires the interaction of multiple agents aligned with the solution to the problem. Teamwork usually requires coordination between the members so that there are no conflicts and the result is more efficient. In the field of artificial learning, when one element is unable to fully learn the solution to a problem, it requires the participation of other “intelligent” elements to fully learn the solution. In this way, a collaborative learning system is presented, in which intelligent agents learn to collaborate with each other in order to achieve complete learning in a self-coordinated way (without a coordinator) and without the occurrence of conflicts between the intelligent elements. Specifically, it involves inserting other neural networks or other intermediate layers into an ANN in order to collaborate with the learning already acquired and thus add new knowledge to the system.”

This is how Prof. Areolino de Almeida Neto describes his presentation entitled “Collaborative learning in artificial neural networks”, which will take place on 15 November at 14:30, room B033.

The talk will be moderated by Prof Carlos Soares (DEI).
