Active Learning for Structured Prediction from Partially Labeled Data

no code implementations7 Jun 2017 Mehran Khodabandeh, Zhiwei Deng, Mostafa S. Ibrahim, Shinichi Satoh, Greg Mori

We propose a general purpose active learning algorithm for structured prediction, gathering labeled data for training a model that outputs a set of related labels for an image or video.

Hierarchical Deep Temporal Models for Group Activity Recognition

1 code implementation9 Jul 2016 Mostafa S. Ibrahim, Srikanth Muralidharan, Zhiwei Deng, Arash Vahdat, Greg Mori

In order to model both person-level and group-level dynamics, we present a 2-stage deep temporal model for the group activity recognition problem.
