Improving Interpretable Embeddings for Ad-hoc Video Search with Generative Captions and Multi-word Concept Bank

no code implementations9 Apr 2024 Jiaxin Wu, Chong-Wah Ngo, Wing-Kwong Chan

Experimental results show that the integration of the above-proposed elements doubles the R@1 performance of the AVS method on the MSRVTT dataset and improves the xinfAP on the TRECVid AVS query sets for 2016-2023 (eight years) by a margin from 2% to 77%, with an average about 20%.

Reinforcement Learning Enhanced PicHunter for Interactive Search

no code implementations 29th International Conference on Multimedia Modeling 2023 Zhixin Ma, Jiaxin Wu, Weixiong Loo, and Chong-Wah Ngo

With these improvements, the interactive system only searches a subset of video datasets relevant to a query while being able to quickly perform Bayesian updates with systematic planning to recommend the most probable candidates that can potentially lead to minimum iteration rounds.
