New framework organizes temporal evidence in hyperbolic space for video retrieval

Researchers have developed a new framework called Hyperbolic Temporal Evidence Organization (HTEO) to improve video moment retrieval. This method embeds temporal representations into hyperbolic space, specifically using a Poincaré ball model, to better capture the relationships between query-relevant evidence, transitions, and distractors. HTEO employs Radial Evidence Organization (REO) and Orthogonal Angular Refinement (OAR) to encode structural differences and enhance semantic alignment. The organized representations are then projected back into Euclidean space and integrated into standard Transformer decoders, with experiments showing improved localization and interpretable geometric organization.
