Researchers have developed ECHO-k, a novel self-supervised learning principle designed to optimize modality acquisition in multimodal AI systems. This method addresses the challenge of costly and often redundant feature acquisition at test time, particularly when the downstream task is unknown. ECHO-k leverages a deep model's internal representations as proxy targets to guide a reinforcement learning policy for sequential modality selection, aiming to improve performance within a given budget.
