"What Artists Want": Elicitation of Artist Requirements to Feed the Design on a New Collaboration Platform for Creative Work
Angeliki Antoniou, Ioanna Lykourentzou, Antonios Liapis +2
Aiming at designing a decentralized platform to support grassroot initiatives for self-organized creative work, the present work solicited feedback from a group of visual artists r…
Towards General Models of Player Experience: A Study Within Genres
David Melhart, Antonios Liapis, Georgios N. Yannakakis
To which degree can abstract gameplay metrics capture the player experience in a general fashion within a game genre? In this comprehensive study we address this question across th…
AffectGAN: Affect-Based Generative Art Driven by Semantics
Theodoros Galanos, Antonios Liapis, Georgios N. Yannakakis
This paper introduces a novel method for generating artistic images that express particular affective states. Leveraging state-of-the-art deep learning methods for visual generatio…
Go-Blend behavior and affect
Matthew Barthet, Antonios Liapis, Georgios N. Yannakakis
This paper proposes a paradigm shift for affective computing by viewing the affect modeling task as a reinforcement learning process. According to our proposed framework the contex…
Privileged Information for Modeling Affect In The Wild
Konstantinos Makantasis, David Melhart, Antonios Liapis +1
A key challenge of affective computing research is discovering ways to reliably transfer affect models that are built in the laboratory to real world settings, namely in the wild.…
Contrastive Learning of Generalized Game Representations
Chintan Trivedi, Antonios Liapis, Georgios N. Yannakakis
Representing games through their pixels offers a promising approach for building general-purpose and versatile game models. While games are not merely images, neural network models…
Monte Carlo Elites: Quality-Diversity Selection as a Multi-Armed Bandit Problem
Konstantinos Sfikas, Antonios Liapis, Georgios N. Yannakakis
A core challenge of evolutionary search is the need to balance between exploration of the search space and exploitation of highly fit regions. Quality-diversity search has explicit…
ARCH-Elites: Quality-Diversity for Urban Design
Theodoros Galanos, Antonios Liapis, Georgios N. Yannakakis +1
This paper introduces ARCH-Elites, a MAP-Elites implementation that can reconfigure large-scale urban layouts at real-world locations via a pre-trained surrogate model instead of c…
The Arousal video Game AnnotatIoN (AGAIN) Dataset
David Melhart, Antonios Liapis, Georgios N. Yannakakis
How can we model affect in a general fashion, across dissimilar tasks, and to which degree are such general representations of affect even possible? To address such questions and e…
Pairing Character Classes in a Deathmatch Shooter Game via a Deep-Learning Surrogate Model
Daniel Karavolos, Antonios Liapis, Georgios N. Yannakakis
This paper introduces a surrogate model of gameplay that learns the mapping between different game facets, and applies it to a generative system which designs new content in one of…
Playing Against the Board: Rolling Horizon Evolutionary Algorithms Against Pandemic
Konstantinos Sfikas, Antonios Liapis
Competitive board games have provided a rich and diverse testbed for artificial intelligence. This paper contends that collaborative board games pose a different challenge to artif…
SuSketch: Surrogate Models of Gameplay as a Design Assistant
Panagiotis Migkotzidis, Antonios Liapis
This paper introduces SuSketch, a design tool for first person shooter levels. SuSketch provides the designer with gameplay predictions for two competing players of specific charac…
Transforming Exploratory Creativity with DeLeNoX
Antonios Liapis, Hector P. Martinez, Julian Togelius +1
We introduce DeLeNoX (Deep Learning Novelty Explorer), a system that autonomously creates artifacts in constrained spaces according to its own evolving interestingness criterion. D…
10 Years of the PCG workshop: Past and Future Trends
Antonios Liapis
As of 2020, the international workshop on Procedural Content Generation enters its second decade. The annual workshop, hosted by the international conference on the Foundations of…
Collaborative Agent Gameplay in the Pandemic Board Game
Konstantinos Sfikas, Antonios Liapis
While artificial intelligence has been applied to control players' decisions in board games for over half a century, little attention is given to games with no player competition.…
The Pixels and Sounds of Emotion: General-Purpose Representations of Arousal in Games
Konstantinos Makantasis, Antonios Liapis, Georgios N. Yannakakis
What if emotion could be captured in a general and subject-agnostic fashion? Is it possible, for instance, to design general-purpose representations that detect affect solely from…
