New AI Sees Like a Human, Filling in the Blanks

How an AI Takes a Few Glimpses and Infers the Whole
A new AI agent developed by researchers at the University of Texas at Austin takes a few “glimpses” of its surroundings, representing less than 20 percent of the full 360 degree view, and infers the rest of the whole environment. What makes this system so effective is that it’s not just taking pictures in random directions but, after each glimpse, choosing the next shot that it predicts will add the most new information about the whole scene.

Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do – take a few quick glimpses around and infer its whole environment, a skill necessary for the development o...

Astronomers using the combined power of two Hawaii telescopes have taken groundbreaking, sharp new images of a distant planetary system that likely resembles a baby version of our solar system.

Using Subaru Telescope and W. M. Keck Observatory, the team obtained and analyzed data for an infant Sun-like star named LkCa 15. Previous studies using an advanced interferometry method had inferred that three infant planets were orbiting this star...

How we make Complex Decisions

MIT neuroscientists are exploring how the brain handles hierarchical decision-making processes that involve breaking down a larger decision into smaller ones that each carry a degree of uncertainty.

Neuroscientists identify a brain circuit that helps break decisions down into smaller pieces. The study sheds light on how the brain reasons about probable causes of failure after a hierarchy of decisions. When making a complex decision, we often break the problem down into a series of smaller decisions. For example, when deciding how to treat a patient, a doctor may go through a hierarchy of steps – choosing a diagnostic test, interpreting the results, and then prescribing a medication.

Making hierarchical decisions is straightforward when the sequence of cho...

Wearable Cooling and Heating Patch could serve as personal Thermostat and Save Energy

Engineers at the University of California San Diego have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user’s skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a flexible, stretchable battery pack and can be embedded in clothing. Researchers say wearing it could help save energy on air conditioning and heating.

“This type of device can improve your personal thermal comfort whether you are commuting on a hot day or feeling too cold in your office,” said Renkun Chen, a professor of mechanical an...
