Learning Cooperative Visual Dialog Agents with Deep Reinforcement Learning

International Conference on Computer Vision (ICCV)

We introduce the first goal-driven training for visual question answering and dialog agents. Specifically, we pose a cooperative ‘image guessing’ game between two agents – Q-BOT and A-BOT– who communicate in natural language dialog so that Q-BOT can select an unseen image from a lineup of images.

Transitive Invariance for Self-supervised Visual Representation Learning

International Conference on Computer Vision (ICCV)

In this paper, we propose to exploit different self-supervised approaches to learn representations invariant to (i) inter-instance variations (two objects in the same class should have similar features) and (ii) intra-instance variations (viewpoint, pose, deformations, illumination, etc.).

Living a Discrete Life in a Continuous World: Reference in Cross-Modal Entity Tracking

Proceedings of IWCS (12th International Conference on Computational Semantics)

This paper (a) introduces a concrete referential task to test both aspects, called cross-modal entity tracking; (b) proposes a neural network architecture that uses external memory to build an entity library inspired in the DRSs of DRT, with a mechanism to dynamically introduce new referents or add information to referents that are already in the library.

STARDATA: a StarCraft AI Research Dataset

Association for the Advancement of Artificial Intelligence Digital Entertainment Conference

We release a dataset of 65646 StarCraft replays that contains 1535 million frames and 496 million player actions. We provide full game state data along with the original replays that can be viewed in StarCraft.

Assessment of Proton Radiation Effects on Hamamatsu InGaAs PIN Photodiodes and Simulated Radiation Responses Using Defect-Based TCAD Modeling

RADiations Effects on Components and Systems (RADECS)

Hamamatsu InGaAs PIN photodiodes were exposed to 105 MeV protons to a fluence of 2.55×1011 p/cm2 . Radiation induced increase in dark current was observed that appeared stable following room temperature annealing. A preliminary TCAD model was developed for use in mixed-mode simulation analyses.

Proton Test Results for a Commercial Fanout Buffer, a Variable Gain Amplifier, and a ±40V Operational Amplifier

RADiations Effects on Components and Systems (RADECS)

Advanced electronics systems require a wide variety of high-performance analog, mixed signal, and clock distribution microcircuits which aren’t readily available as space-qualified components.

Propagation of Joint Space Quantization Error to Operational Space Coordinates and Their Derivatives

IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

In this paper, we characterize encoder error in a robotic system. Given encoder specifications, robot kinematics, and discrete transfer functions mapping coordinates to their derivatives, we describe the propagation of quantization error on joint space coordinates to operational space coordinates, joint space coordinate derivatives, and operational space coordinate derivatives.

100Gb/s CWDM4 Optical Interconnect at Facebook Data Centers for Bandwidth Enhancement

Frontiers in Optics / Laser Science (FiO/LS)

Facebook has developed 100G data centers from the ground-up by fine tuning optical technologies, optimizing link-budget, limiting operating temperatures and ultimately improving manufacturability. 100G-CWDM4 is an effective technology to enable connectivity over duplex single-mode fiber.
