Timeception for Complex Action RecognitionCVPR, 2019Oral Presentation
Noureldien Hussein, Efstratios Gavves, Arnold W. M. Smeulders

A novel temporal layer for 3D CNNs with multi-scale temporal convolutions and much reduced computation. The result is a CNN for modeling minute-long complex actions, 8 times longer than best related method.

Unified Embedding and Metric Learning for Zero-Exemplar Event DetectionCVPR, 2017
Noureldien Hussein, Efstratios Gavves, Arnold W. M. Smeulders

A manifold is learned using contrastive loss, in which there is a joint embedding of videos of human events and their related articles. The result is end-to-end model with best results on TRECVID MED dataset.
