(via sciencedaily.com) Original source An open source code library for brain-inspired deep learning, called 'snnTorch,' has surpassed 100,000 downloads and is used in a wide variety of projects. A new paper details the code and offers a perspective on the future of the field.
Published The mind's eye of a neural network system
(via sciencedaily.com) Original source A new tool, based on topology, makes finding the areas where neural networks are confused as simple as spotting mountaintops from an airplane. The ability to spot and address those areas of confusion should enable more confident application of neural networks in high-stakes decision scenarios or image prediction tasks like healthcare and research.
Published No one-size-fits-all solution for the net-zero grid
(via sciencedaily.com) Original source As power generation from sources like solar and wind increases, along with the introduction of devices such as heat pumps and batteries, a new optimization tool will help the UK plan for a greener electricity network. The researchers developed an algorithm to model how these smaller networks distributed electricity -- factoring in how local grids could become unbalanced by adding too many heat pumps in a single area or generating more electricity than the grid could accept.
Published Nuclear expansion failure shows simulations require change
(via sciencedaily.com) Original source A team of researchers looked back at a model that predicted nuclear power would expand dramatically in order to assess the efficacy of energy policies implemented today.
Published Realistic talking faces created from only an audio clip and a person's photo
(via sciencedaily.com) Original source A team of researchers has developed a computer program that creates realistic videos that reflect the facial expressions and head movements of the person speaking, only requiring an audio clip and a face photo. DIverse yet Realistic Facial Animations, or DIRFA, is an artificial intelligence-based program that takes audio and a photo and produces a 3D video showing the person demonstrating realistic and consistent facial animations synchronised with the spoken audio (see videos).
Published Use it or lose it: New robotic system assesses mobility after stroke
(via sciencedaily.com) Original source Stroke is a leading cause of long-term disability worldwide. Each year more than 15 million people worldwide have strokes, and three-quarters of stroke survivors will experience impairment, weakness and paralysis in their arms and hands. Many stroke survivors rely on their stronger arm to complete daily tasks, from carrying groceries to combing their hair, even when the weaker arm has the potential to improve.
Published This 3D printer can watch itself fabricate objects
(via sciencedaily.com) Original source Engineers have developed a high-throughput, multimaterial 3D inkjet printer that uses computer vision to rapidly and automatically control the amount of material being deposited during the printing process in real time. This enables the use of a wide range of materials for fabrication.
Published New twist on AI makes the most of sparse sensor data
(via sciencedaily.com) Original source An innovative approach to artificial intelligence (AI) enables reconstructing a broad field of data, such as overall ocean temperature, from a small number of field-deployable sensors using low-powered 'edge' computing, with broad applications across industry, science and medicine.
Published New tool models viability of closed-loop geothermal systems
(via sciencedaily.com) Original source Researchers have used computer models of closed-loop geothermal systems to determine if they would be economically viable sources of renewable energy. They found that the cost of drilling would need to decrease significantly to hit cost targets.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com) Original source Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Twisted magnets make brain-inspired computing more adaptable
(via sciencedaily.com) Original source Researchers used chiral (twisted) magnets as their computational medium and found that, by applying an external magnetic field and changing temperature, the physical properties of these materials could be adapted to suit different machine-learning tasks.
