Researchers have introduced a new two-stage multi-modal learning framework designed to improve dynamic audio-visual navigation (D-AVN) for agents. The first stage, an Intensity-Calibrated Geometry Encoder, aligns sound intensity with visual geometry for category-agnostic spatial understanding. The second stage, a Cross-Modal Scene Aggregator, uses a Transformer to integrate multi-modal features for robust state representation. Experiments on Replica and Matterport3D datasets show this approach achieves state-of-the-art results, enhancing generalization and navigation efficiency, particularly for unheard sound categories.
