<p>
Contrastive learning-based video-language representation learning approaches,
e.g., CLIP, have achieved outstanding performance, which pursue semantic interaction
upon pre-defined video-text pairs. To clarify this coarse-grained global interaction
and move a step further, we have to encounter challenging shell-breaking interactions
for fine-grained cross-modal learning.
In this paper, we creatively model video-text as
game players with multivariate cooperative game theory to wisely handle the uncertainty
during fine-grained semantic interaction with diverse granularity, flexible combination,
and vague intensity. Concretely, we propose Hierarchical Banzhaf
Interaction (HBI) to value possible correspondence between video frames and
text words for sensitive and explainable cross-modal contrast. To efficiently realize the
cooperative game of multiple video frames and multiple text words, the proposed method
clusters the original video frames (text words) and computes the Banzhaf Interaction
between the merged tokens. By stacking token merge modules, we achieve cooperative games
at different semantic levels.
Extensive experiments on commonly used text-video retrieval and video-question answering
benchmarks with superior performances justify the efficacy of our HBI. More encouragingly,
it can also serve as a visualization tool to promote the understanding of cross-modal
interaction, which have a far-reaching impact on the community.
