Social interactions happen in many forms. In particular, when dealing with multi-person scenarios, the presence of competitive or cooperative interactions is not uncommon. Adapting artificial agents, whether embodied robots, or virtual avatars, to perform complex social interactions means we must take into consideration competitive and/or cooperative characteristics. Artificial agents with the ability to deal with these characteristics are still not a reality, although several researchers focused on solving these problems in the last decades based on the individual perspectives of Human-Robot Interaction (HRI) or machine learning. Recently, we did see substantial advancements in the understanding of social signals, in the modeling of multi-agent interaction, and in the development of embodied and intelligent avatars.
Yet, these are often confined to individual approaches, such as reinforcement learning or wizard-of-oz interactions, or constrained environments, for instance virtual simulations or lab-only contexts. As a result we do not see the embracing of these technologies in the mainstream solutions for real-world human-computer and human-robot interaction. Also, most of the research in these areas does not take into consideration all the technological, social, and ethical impacts of such applications. In this workshop, we put together the top-tier researchers on machine learning, in particular social signal processing, and human-robot interaction to discuss, understand and propose possible solutions for our overall topic “Competition and Cooperation: How to integrate machine learning and human-robot interaction in meaningful applications?”. Our intention is to leverage a enriching discussion of the existing problems on competitive and cooperative interactions on the multidisciplinary view of our contributors, and not to present individual solutions for each of the related topics. Our invited speakers, all experts in their respective areas, will discuss the open problems involving social agents interactions within their specialty. We also invite the submissions of position papers that present a critical view on this topic to complement and widen our discussions.

Most of the current Reinforcement-Learning solutions, although having real-world-inspired scenarios, focus on a direct space-action-reward mapping between the agent's actions and the environment’s state. That translates to agents that can adapt to dynamic scenarios, but, when applied to competitive and/or cooperative cases, fail to assess and deal with the impact of their opponents. In most cases, when these agents choose an action, they do not take into consideration how other agents can affect the state of the scenario. In competitive scenarios, the agents have to learn decisions that a) maximize their chances of winning the game, and b) minimize their adversaries' goals, while in cooperative scenarios b) is inverted. Besides dealing with complex scenarios, such solutions would have to deal with the dynamics between the agents themselves. In this regard, social reinforcement learning is still behind the mainstream applications and demonstrations of the last years.
We recently introduced a card game scenario for reinforcement learning, named Chef’s Hat, which contains specific mechanics that allow complex dynamics between the players to be used in the development of a winning game strategy. A card game scenario allows us to have a naturally-constrained environment and yet obtain responses that are the same as the real-world counterpart application. Chef’s Hat implements game and interaction mechanics that make it easier to be transferred between the real-world scenario and the virtual environment.
Our challenge will be based on Chef’s Hat and will be separated into two tracks: a competitive and a cooperative scenario. In the first track, the participants will use the already available simulation environment to develop the most effective agents to play the Chef’s Hat card game and be the winner. In the second track, they will have to develop an agent that can increase the chances of a dummy agent winning the game.
Each participant has to produce up to five agents that have learned how to play the game. For each track, the winner will be chosen based on the track’s specific goal. For both tracks, each competitor will pass through the following process:
