Tech Xplore / New technique reduces bias in AI models while preserving or improving accuracy
Machine-learning models can fail when they try to make predictions for individuals who were underrepresented in the datasets they were trained on.
Tech Xplore / Global building height prediction made easy with machine learning
As cities continue to grow globally, characterizing the built environment is essential to understanding human populations, projecting energy usage, monitoring urban heat island impacts, preventing environmental degradation, ...
Tech Xplore / Novel green solvent could help scale up fabrication of perovskite-based tandem solar cells
In recent years, engineers have been trying to develop alternative photovoltaic (PV) technologies that could be more affordable and scalable than silicon-based solar cells, while also exhibiting good power-conversion efficiencies ...
Tech Xplore / Desalination system also produces hydrogen, electricity and cool air for refrigeration
A pair of engineers at Hamad Bin Khalifa University has developed a desalination system that also produces electricity, hydrogen and cool air for refrigeration. In their paper published in the journal Desalination Nurettin ...
Tech Xplore / Quantum computing's next step: New algorithm boosts multitasking
Quantum computers differ fundamentally from classical ones. Instead of using bits (0s and 1s), they employ "qubits," which can exist in multiple states simultaneously due to quantum phenomena like superposition and entanglement.
Dialog / Chalcogenide perovskites: The next frontier in solar technology?
For decades, silicon has been the backbone of the solar industry, but it's nearing its theoretical efficiency limit of 29.4%. To push beyond this cap, scientists are turning to tandem solar cells, which have layered materials ...
Tech Xplore / Some language reward models exhibit political bias even when trained on factual data
Large language models (LLMs) that drive generative artificial intelligence apps, such as ChatGPT, have been proliferating at lightning speed and have improved to the point that it is often impossible to distinguish between ...
Tech Xplore / AI model allows for near-instant image creation on consumer-grade hardware
An AI model that creates images as the user types, using only modest and affordable hardware, has been announced by the Surrey Institute for People-Centred Artificial Intelligence (PAI) at the University of Surrey.
Tech Xplore / Stabilizing ligand enables 22% efficiency in all-inorganic perovskite cells
An international team of physicists, chemists and electronic engineers reports that a stabilizing ligand enables all-inorganic perovskite cells with an efficiency of up to 22%. In their study, published in the journal Nature, ...
Tech Xplore / Shape-changing device helps visually impaired people perform location task as well as sighted people
A piece of navigation technology that uses the ability to sense information through touch can help people with visual impairment perform a location task as well as sighted people, according to new Imperial-led research.
Tech Xplore / Prototype network achieves seamless all-light mobile communication across air, land and sea
Researchers have demonstrated a prototype mobile all-light communication network, paving the way for seamless connectivity across air, land and underwater environments—even when communication nodes are on a moving vehicle. ...
Tech Xplore / Enabling AI to explain its predictions in plain language
Machine-learning models can make mistakes and be difficult to use, so scientists have developed explanation methods to help users understand when and how they should trust a model's predictions.
