Differentiable Plasticity: A New Method Learning to Learn

Neural networks, which underlie many of Uber’s machine learning systems, have proven highly successful in solving complex problems, including image recognition, language understanding, and game-playing. However, these networks are usually trained to a stopping point through gradient descent, which incrementally adjusts the connections of the network based on its performance over many trials. Once the training is complete, the network is fixed and the connections can no longer change; as a result, barring any later re-training (again requiring many examples), the network in effect stops learning at the moment training ends.

NASA X-Plane Construction Begins

To that end, NASA on April 2 awarded a $247.5 million contract to Lockheed Martin Aeronautics Company of Palmdale, Calif., to build the X-plane and deliver it to the agency’s Armstrong Flight Research Center in California by the end of 2021.

Breakthrough Announced in Dark Matter Detection Technology

This week, the Axion Dark Matter Experiment (ADMX) unveiled a new result, published in the journal Physical Review Letters, that places it in a category of one: it is the world’s first and only experiment to have achieved the necessary sensitivity to “hear” the telltale signs of dark matter axions. This technological breakthrough is the result of more than 30 years of research and development, with the latest piece of the puzzle coming in the form of a quantum-enabled device that allows ADMX to listen for axions more closely than any experiment ever built.

The Case Against an Autonomous Military

The potential harm of A.I.s deliberately designed to kill in warfare is much more pressing. The U.S. and other countries are working hard to develop military A.I., in the form of automated weapons, that enhance battlefield capabilities while exposing fewer soldiers to injury or death. For the U.S., this would be a natural extension of the existing imperfect drone warfare program—failures in military intelligence have led to the mistaken killing of non-combatants in Iraq.

ACE Submarine Cable Cut Impacts Ten Countries

The ACE (African Coast to Europe) submarine cable runs along the west coast of Africa between France and South Africa, connecting 22 countries. It extends over 17,000 km, and has a potential capacity of 5.12 Tbps. The cable system is managed by a consortium of 19 telecommunications operators & administrations, and the first phase entered service in December 2012.

DeepMarks: A Digital Fingerprinting Framework for Deep Neural Networks

DeepMarks introduces the first fingerprinting methodology that enables the model owner to embed unique fingerprints within the parameters (weights) of her model and later identify undesired usages of her distributed models. The proposed framework embeds the fingerprints in the Probability Density Function (pdf) of trainable weights by leveraging the extra capacity available in contemporary DL models. DeepMarks is robust against fingerprints collusion as well as network transformation attacks, including model compression and model fine-tuning.
