Learning by gaming:ANT and critical making
Relationships among theory, gaming, learning and socio-technical design are explored in the two contributions which compose the section. The theory in question is ANT, re-interpreted through critical making - an umbrella term for various distinctive practices that link traditional scholarship in the humanities and social sciences to forms of material engagement. Sergio Minniti describes an ongoing project called Game of ANT, which draws upon the critical making approach to design an interactive technology and a workshop experience through which scholars and students can conceptually-materially engage with ANT, hence exploring and approaching it from novel points of view. Game of ANT adopts the Latourian vision of technoscience as war and physically embodies this idea by proposing a sort of war game during which participants play the roles of human or non-human actors engaging with the competitive dynamics of socio-technical life. The commentary by Stefano De Paoli proposes new directions to develop the project, by deepening the concept of game and its value for design and learning processes.</p
A Serious Game Approach in Anti-Doping Education: the Game Project
Anti-doping education has largely relied on traditional educational approaches such as face-to-face interaction and e-learning material. Current challenges in anti-doping education involve a) the development of modern educational tools suitable for the new generation of athletes, b) the use of state-of- art learning pedagogies that will enable effective engagement, learning and retention of the learned material, c) a systematic evaluation of the outcomes of anti-doping educational interventions on behavior and related cognition, and d) a positive approach to doping prevention. Project GAME aims to address these needs through the development of a serious game that will incorporate current empirical evidence on the psychological mechanisms underpinning the decision making process towards doping use in competitive and recreational sports. The aim of the present study is to highlight the importance of anti-doping education, conduct a state of the art literature review on serious games' design, present the prototype of a scenario that will be included in a serious game for anti-doping education, and discuss the project's activities related to the use of technologies in anti-doping education. +++++++++++++ Anti-doping education has largely relied on traditional educational aproaches such as face-to-face interaction and e-learning material.

Minimax Exploiter: A Data Efficient Approach for Competitive Self-Play
Recent advances in Competitive Self-Play (CSP) have achieved, or even
surpassed, human level performance in complex game environments such as Dota 2
and StarCraft II using Distributed Multi-Agent Reinforcement Learning (MARL).
One core component of these methods relies on creating a pool of learning
agents -- consisting of the Main Agent, past versions of this agent, and
Exploiter Agents -- where Exploiter Agents learn counter-strategies to the Main
Agents. A key drawback of these approaches is the large computational cost and
physical time that is required to train the system, making them impractical to
deploy in highly iterative real-life settings such as video game productions.
In this paper, we propose the Minimax Exploiter, a game theoretic approach to
exploiting Main Agents that leverages knowledge of its opponents, leading to
significant increases in data efficiency. We validate our approach in a
diversity of settings, including simple turn based games, the arcade learning
environment, and For Honor, a modern video game. The Minimax Exploiter
consistently outperforms strong baselines, demonstrating improved stability and
data efficiency, leading to a robust CSP-MARL method that is both flexible and
easy to deploy
Semantic Labelling and Learning for Parity Game Solving in LTL Synthesis
We propose "semantic labelling" as a novel ingredient for solving games in
the context of LTL synthesis. It exploits recent advances in the automata-based
approach, yielding more information for each state of the generated parity game
than the game graph can capture. We utilize this extra information to improve
standard approaches as follows. (i) Compared to strategy improvement (SI) with
random initial strategy, a more informed initialization often yields a winning
strategy directly without any computation. (ii) This initialization makes SI
also yield smaller solutions. (iii) While Q-learning on the game graph turns
out not too efficient, Q-learning with the semantic information becomes
competitive to SI. Since already the simplest heuristics achieve significant
improvements the experimental results demonstrate the utility of semantic
labelling. This extra information opens the door to more advanced learning
approaches both for initialization and improvement of strategies
A Novel Graphical Lasso based approach towards Segmentation Analysis in Energy Game-Theoretic Frameworks
Energy game-theoretic frameworks have emerged to be a successful strategy to
encourage energy efficient behavior in large scale by leveraging
human-in-the-loop strategy. A number of such frameworks have been introduced
over the years which formulate the energy saving process as a competitive game
with appropriate incentives for energy efficient players. However, prior works
involve an incentive design mechanism which is dependent on knowledge of
utility functions for all the players in the game, which is hard to compute
especially when the number of players is high, common in energy game-theoretic
frameworks. Our research proposes that the utilities of players in such a
framework can be grouped together to a relatively small number of clusters, and
the clusters can then be targeted with tailored incentives. The key to above
segmentation analysis is to learn the features leading to human decision making
towards energy usage in competitive environments. We propose a novel graphical
lasso based approach to perform such segmentation, by studying the feature
correlations in a real-world energy social game dataset. To further improve the
explainability of the model, we perform causality study using grangers
causality. Proposed segmentation analysis results in characteristic clusters
demonstrating different energy usage behaviors. We also present avenues to
implement intelligent incentive design using proposed segmentation method.Comment: Proceedings of the Special Session on Machine Learning in Energy
