Learning Contextual Causality from Time-consecutive Images

1 code implementation13 Dec 2020 Hongming Zhang, Yintong Huo, Xinran Zhao, Yangqiu Song, Dan Roth

Compared with pure text-based approaches, learning causality from the visual signal has the following advantages: (1) Causality knowledge belongs to the commonsense knowledge, which is rarely expressed in the text but rich in videos; (2) Most events in the video are naturally time-ordered, which provides a rich resource for us to mine causality knowledge from; (3) All the objects in the video can be used as context to study the contextual property of causal relations.
