Alexei A. Efros

Howard Friesen Professor in UC Berkeley EECS and member of BAIR; co-author of pix2pix and CycleGAN

Alexei A. Efros (Alyosha) is the Howard Friesen Professor in the EECS Department at UC Berkeley and part of the Berkeley Artificial Intelligence Research Lab (BAIR), after a decade on the faculty of the Robotics Institute at Carnegie Mellon University. Efros's research uses large amounts of unlabeled visual data to understand, model, and recreate the visual world, mainly in data-driven computer vision and its links to computer graphics and computational photography, with interests that include self-supervised learning and world models. Efros is a co-author of the image-to-image translation papers known as pix2pix (2016) and CycleGAN (2017), whose public code repositories list Efros among the authors.12345
