Natural Questions: a New Corpus and Challenge for Question Answering Research
To help spur research advances in QA, we are excited to announce Natural Questions (NQ), a new, large-scale corpus for training and evaluating open-domain question answering systems, and the first to replicate the end-to-end process in which people find answers to questions.

AlphaStar: Mastering the Real-Time Strategy Game StarCraft II
Now, we introduce our StarCraft II program AlphaStar, the first Artificial Intelligence to defeat a top professional player. In a series of test matches held on 19 December, AlphaStar decisively beat Team Liquid’s Grzegorz “MaNa” Komincz, one of the world’s strongest professional StarCraft players, 5-0, following a successful benchmark match against his team-mate Dario “TLO” Wünsch. The matches took place under professional match conditions on a competitive ladder map and without any game restrictions.

Filling Holes: Adobe Proposes Foreground-Aware Image Inpainting
Existing image inpainting methods fill holes by borrowing information from surrounding image regions. These methods however produce unsatisfactory results if holes overlap with foreground objects, suffering from a “lack of information about the actual extent of foreground and background regions with the holes.”

3D Human Pose Machines with Self-supervised Learning
This paper proposes a simple yet effective self-supervised correction mechanism to learn all intrinsic structures of human poses from abundant images. Specifically, the proposed mechanism involves two dual learning tasks, i.e., the 2D-to-3D pose transformation and 3D-to-2D pose projection, to serve as a bridge between 3D and 2D human poses in a type of “free” self-supervision for accurate 3D human pose estimation.
