Temporal Action Detection with Multi-level Supervision

Baifeng Shi, Qi Dai, Judy Hoffman +3

Training temporal action detection in videos requires large amounts of labeled data, yet such annotation is expensive to collect. Incorporating unlabeled or weakly-labeled data to…

Auxiliary Task Reweighting for Minimum-data Learning

Baifeng Shi, Judy Hoffman, Kate Saenko +2

Supervised learning requires a large amount of training data, limiting its application where labeled data is scarce. To compensate for data scarcity, one possible method is to util…

Spatio-Temporal Action Detection with Multi-Object Interaction

Huijuan Xu, Lizhi Yang, Stan Sclaroff +2

Spatio-temporal action detection in videos requires localizing the action both spatially and temporally in the form of an "action tube". Nowadays, most spatio-temporal action detec…

Weakly-Supervised Action Localization with Expectation-Maximization Multi-Instance Learning

Zhekun Luo, Devin Guillory, Baifeng Shi +4

Weakly-supervised action localization requires training a model to localize the action segments in the video given only video level action label. It can be solved under the Multipl…

Revisiting Few-shot Activity Detection with Class Similarity Control

Huijuan Xu, Ximeng Sun, Eric Tzeng +3

Many interesting events in the real world are rare making preannotated machine learning ready videos a rarity in consequence. Thus, temporal activity detection models that are able…

Something-Else: Compositional Action Recognition with Spatial-Temporal Interaction Networks

Joanna Materzynska, Tete Xiao, Roei Herzig +3

Human action is naturally compositional: humans can easily recognize and perform actions with objects that are different from those used in training demonstrations. In this paper,…
