Video-Language Representation Learning
Video-Language Representation Learning connects videos with their text descriptions. It is useful in areas like question answering, text retrieval, and summarization. A key technique in this field is contrastive learning, which helps networks learn important features by analyzing video-text pairs.
Challenges in Current Methods
However, current models struggle with fine details in video annotations, leading to lower performance in specific tasks. Creating a large dataset of high-quality annotations could help, but such datasets are often not available.
Innovative Solution: Hierarchical Banzhaf Interaction (HBI V2)
Researchers from Peking University and Pengcheng Laboratory have developed a new approach called HBI V2. This method treats video and text as players in a cooperative game to improve alignment in video-language learning.
How HBI V2 Works
HBI V2 combines single-modal and cross-modal representations to enhance learning. It reconstructs representations dynamically, ensuring detailed information is preserved while improving interactions between video and text.
Benefits of HBI V2
This framework excels in various tasks, including text-video retrieval, VideoQA, and video captioning. It features a flexible encoder-decoder structure that adapts to different tasks without complex fusion processes.
Performance and Evaluation
HBI V2 has been tested on multiple datasets and has outperformed previous methods, achieving impressive results in question answering. It also has a quick inference time of just one second for the entire test data.
Conclusion
HBI V2 effectively uses Banzhaf Interaction to provide detailed labels for video-text relationships without needing manual annotations. This framework is versatile and superior for various tasks.
