Siamese Learning with Joint Alignment and Regression for Weakly-Supervised Video Paragraph Grounding

no code implementations18 Mar 2024 Chaolei Tan, JianHuang Lai, Wei-Shi Zheng, Jian-Fang Hu

Different from previous weakly-supervised grounding frameworks based on multiple instance learning or reconstruction learning for two-stage candidate ranking, we propose a novel siamese learning framework that jointly learns the cross-modal feature alignment and temporal coordinate regression without timestamp labels to achieve concise one-stage localization for WSVPG.
