T-JEPA: A Temporal Joint-Embedding Predictive Architecture for Learning Better Remote Sensing Representations

Bowen Peng, Li Liu, Yongxiang Liu وآخرون · 2026

Earth observation (EO) data provide rich temporal supervision, yet existing remote sensing foundation models mainly exploit sequential observations through imposing predefined pairwise relations or aggregating holistic reconstruction context. We seek to further exploit the sparse and nonuniform temporal sampling inhere …

CurvSpec: Adaptive Multi-Curvature Learning for Partial Relevant Video Retrieval

Zhen Liu, Letian Li, Jinpeng Wang وآخرون · 2026 · 10.1145/3767308.3835167

Partially Relevant Video Retrieval (PRVR) seeks to retrieve untrim-med videos containing a moment that matches a text query, without temporal annotations. The relevant moment may last only seconds within a video spanning several minutes, creating an extremely low signal-to-noise ratio that makes PRVR more challenging t …
