Amir R. Zamir

About Me:

I'm a postdoctoral researcher at Stanford and UC Berkeley with Silvio Savarese and Jitendra Malik. I also work closely with Leonidas Guibas. My research interests are broadly in computer vision, machine learning, and AI with a focus on multi-task transfer/selfsupervised/unsupervised learning and perception-for-robotics. The goal of my research is going beyond narrow and offline perception methods and moving toward a general multi-task visual perception that operates as part of an active body in the real world. Here are my sample research (Taskonomy, Mid-Level Vision, Gibson), community, and teaching works on this topic. I'm also interested in structured prediction, video understanding, and 3D vision.
