Scholarship opportunity in TÜBİTAK funded project

I am looking for MSc/PhD students in METU to work on GPU development in a TÜBİTAK funded project to work in collaboration with TÜBİTAK-UZAY. The scholarship will start in June 2017 and will be for a fixed term of 36 months. Please send me an e-mail with your CV if you are interested.

Multimodal Egocentric Activity Recognition Seminar

I’ll be giving a seminar on Multimodal Egocentric Activity Recognition at the Computer Science Department – University of Bristol on 7th Feb 2017 at 12:00.

In the talk, I will be focussing on the particular challenges regarding the activity recognition from egocentric (first-person) data and data-driven selection and weighting of different features.
