Stable Deep Reinforcement Learning via Isotropic Gaussian Representations

Ali Saheb Pasand, Johan Obando-Ceron, Aaron Courville +2

Deep reinforcement learning systems often suffer from unstable training dynamics due to non-stationarity, where learning objectives and data distributions evolve over time. We show…

The Intricate Dance of Prompt Complexity, Quality, Diversity, and Consistency in T2I Models

Zhang Xiaofeng, Aaron Courville, Michal Drozdzal +1

Text-to-image (T2I) models offer great potential for creating virtually limitless synthetic data, a valuable resource compared to fixed and finite real datasets. Previous works eva…

Bias Analysis in Unconditional Image Generative Models

Xiaofeng Zhang, Michelle Lin, Simon Lacoste-Julien +2

The widespread adoption of generative AI models has raised growing concerns about representational harm and potential discriminatory outcomes. Yet, despite growing literature on th…
