• Abstract: Procedural content generation via machine learning (PCGML) in games involves using machine learning techniques to create game content such as maps and levels. 2D tile-based game levels have consistently served as a standard dataset for PCGML because they are a simplified version of game levels while maintaining the specific constraints typical of games, such as being solvable. In this work, we highlight the unique characteristics of game levels, including their structured discrete data nature, the local and global constraints inherent in the games, and the sensitivity of the game levels to small changes in input. We define the robustness of data as a measure of sensitivity to small changes in input that cause a change in output, and we use this measure to analyze and compare these levels to state-of-the-art machine learning datasets, showcasing the subtle differences in their nature. We also constructed a large dataset from four games inspired by popular classic tile-based games that showcase these characteristics and address the challenge of sparse data in PCGML by providing a significantly larger dataset than those currently available.

  We revisit the paradigm of generative games to explore what truly constitutes a Model as a Game (MaaG) with a well-developed mechanism.<n>Based on the DiT architecture, we design two specialized modules: (1) a numerical module that integrates a LogicNet to determine event triggers, with calculations processed externally as conditions for image generation; and (2) a spatial module that maintains a map of explored areas, retrieving location-specific information during generation and linking new observations to ensure continuity.

• Multi-Environment Pretraining Enables Transfer to Action Limited Datasets [129.24823721649028]
  In reinforcement learning, available data of decision making is often not annotated with actions. We propose combining large but sparsely-annotated datasets from a emphtarget environment of interest with fully-annotated datasets from various other emphsource environments. We show that utilizing even one additional environment dataset of sequential labelled data during IDM pretraining gives rise to substantial improvements in generating action labels for unannotated sequences.

• Personalized Game Difficulty Prediction Using Factorization Machines [0.9558392439655011]
  We contribute a new approach for personalized difficulty estimation of game levels, borrowing methods from content recommendation. We are able to predict difficulty as the number of attempts a player requires to pass future game levels, based on observed attempt counts from earlier levels and levels played by others. Our results suggest that FMs are a promising tool enabling game designers to both optimize player experience and learn more about their players and the game.

  We present tile embeddings, a unified, affordance-rich representation for tile-based 2D games. We employ autoencoders trained on the visual and semantic information of tiles from a set of existing, human-annotated games. We evaluate this representation on its ability to predict affordances for unseen tiles, and to serve as a PLGML representation for annotated and unannotated games.
