Deconfounded Video Moment Retrieval with Causal Intervention [article]

Xun Yang, Fuli Feng, Wei Ji, Meng Wang, Tat-Seng Chua
2021 arXiv   pre-print
We tackle the task of video moment retrieval (VMR), which aims to localize a specific moment in a video according to a textual query.  ...  It first disentangles moment representation to infer the core feature of visual content, and then applies causal intervention on the disentangled multimodal input based on backdoor adjustment, which forces  ...  Causal Graph We describe the causalities among four variables in VMR: query , video moment , moment location , and model prediction with a simple causal graph in Figure 1 (b).  ...

Interventional Video Grounding with Dual Contrastive Learning [article]

Guoshun Nan, Rui Qiao, Yao Xiao, Jun Liu, Sicong Leng, Hao Zhang, Wei Lu
2021 arXiv   pre-print
we first propose a novel paradigm from the perspective of the causal inference, i.e., interventional video grounding (IVG) that leverages backdoor adjustment to deconfound the selection bias based on  ...  Video grounding aims to localize a moment from an untrimmed video for a given textual query.  ...  Despite these success, directly applying these causal methods to the video grounding task may not yield good results, due to the more complex interactions for moment retrieval compared with the image-based  ...

Weakly-Supervised Video Object Grounding via Causal Intervention [article]

Wei Wang, Junyu Gao, Changsheng Xu
2021 arXiv   pre-print
With this in mind, we design a unified causal framework to learn the deconfounded object-relevant association for more accurate and robust video object grounding.  ...  Specifically, we learn the object-relevant association by causal intervention from the perspective of video data generation process.  ...  Specifically, for video moment retrieval, Yang et al.  ...
