Oğuzhan Fatih Kar

I am a Ph.D. student in Computer Science at the Swiss Federal Institute of Technology (EPFL), where I am advised by Amir Zamir. My current research interests are in building robust, adaptive, and multimodal perception systems that can scale and operate in the real world. My recent works on this topic are BRAVE, 4M & 4M-21, Rapid Network Adaptation, 3D Common Corruptions, and Cross-Domain Ensembles.

I received the B.S. and M.S. degrees in Electrical Engineering at METU, where I have worked with Figen Oktem. My M.S. work had focused on developing high-resolution and compressive reconstruction techniques for computational imaging.

Update: I am starting to look for research scientist positions. Feel free to reach out to discuss potential opportunities or collaborations.

Misc

Robustness and uncertainty estimation for visual perception

This is a presentation I made on the relation between robustness and uncertainty in computer vision. The video also includes an overview of three important papers in uncertainty estimation in deep learning models.
