Abstract
Human posture estimation, also referred as human pose estimation, is a well-researched computer vision topic due to its importance in a large number of application areas, such as monitoring, surveillance, human-robot interaction, etc.. 2D/3D human posture estimation typically entails estimating the 2D pixel/3D world coordinates of a predefined set of human body joints given an input image, while other body posture representations (body parts, 3D angles, etc.) have also been used in the literature. Deep Convolutional Neural Networks (CNNs) are an effective algorithmic approach to this end that has achieved remarkable results. A great application area is human-robot collaboration, e.g, for ensuring safety, by enabling robots to autonomously maintain a safe distance from humans.

Brief Bio
Michal Irani is a Professor at the Weizmann Institute of Science, Israel, in the Department of Computer Science and Applied Mathematics. She received a B.Sc. degree in Mathematics and Computer Science from the Hebrew University of Jerusalem, and M.Sc. and Ph.D. degrees in Computer Science from the same institution. During 1993-1996 she was a member of the Vision Technologies Laboratory at the Sarnoff Research Center (Princeton). She joined the Weizmann Institute in 1997. Michal's research interests center around Computer-Vision, Image-Processing, Artificial-Intelligence and Video information analysis. Michal's prizes and honors include the David Sarnoff Research Center Technical Achievement Award (1994), the Yigal Alon three-year Fellowship for Outstanding Young Scientists (1998), the Morris L. Levinson Prize in Mathematics (2003), the Maria Petrou Prize (awarded by the IAPR) for outstanding contributions to the fields of Computer Vision and Pattern Recognition (2016), the Landau Prize in Artificial Intelligence (2019), and the Rothschild Prize in Mathematics and Computer Science (2020). She received the ECCV Best Paper Award in 2000 and in 2002, and was awarded the Honorable Mention for the Marr Prize in 2001 and in 2005. In 2017 Michal received the Helmholtz Prize – the “Test of Time Award” (for the paper “Actions as space-time shapes”).
Abstract
In this talk I will show how Deep-Learning can be performed without any prior examples, by training on a single image – the test image alone. The strong recurrence of information inside a single natural image provides powerful internal examples which suffice for self-supervision of Deep-Networks, thus giving rise to true “Zero-Shot Learning”. I will show the power of this approach to a variety of problems, including: super-resolution (in space and in time), image-segmentation, transparent layer separation, image-dehazing, and more.
I will further show how self-supervision can be used also for “Mind-Reading” (recovering observed visual information from fMRI brain recordings), when only few fMRI training examples are available.

Abstract
Artificial Intelligence (AI) has become ubiquitous and we, as a society, have become AI consumers. Today the debate around AI in terms of its definition, risks, economic impact, and safety is more lively than ever. As technology and products become more mature, companies are starting to realize the need for investing in more responsible and transparent AI systems. We've also observed in the last years a change from a mode-centric approach, to a data-centric view, where the emphasis is placed on the quality of the data. However, ethical, fair, unbiased data comes at a cost. And, on our road to data democratization, we cannot forget about these sustainability pillars for AI systems. In this keynote, we will talk about the challenges in the creation of ethical, fair, and unbiased datasets and the importance of having an ethical data stamp that guarantees that we leave no one out.
