External system improves phones’ signal strength 1,000 percent, without requiring extra antennas.

Routing scheme boosts efficiency in networks that help speed up blockchain transactions.

In a lively poster session, more than 100 undergraduates discuss their yearlong research projects on everything from machine learning to political geography.

Computer scientists’ new method could help doctors avoid ineffective or unnecessarily risky treatments.

Model tags road features based on satellite images, to improve GPS navigation in places with limited map data.

Models that map these relationships based on patient data require fine-tuning for certain conditions, study shows.

Using mathematical theory, Virginia Williams coaxes algorithms to run faster or proves they’ve hit their maximum speed.

Machine-learning system should enable developers to improve computing efficiency in a range of applications.

A new computational imaging method could change how we view hidden information in scenes.

Model registers “surprise” when objects in a scene do something unexpected, which could be used to build smarter AI.
