A prosthodontic digital guide for reproducing lip–instrument positioning for wind instruments

A digitally fabricated guide developed by researchers at Science Tokyo captures and reproduces the spatial relationship between a musician's lips and an air-reed instrument, such as a shakuhachi flute. By combining facial ...

AI imagines a harsher social world, expecting punishment where people expect inaction

Artificial intelligence (AI) systems, particularly the large language models (LLMs) that underpin ChatGPT and similar platforms, are remarkably skilled at answering queries about a wide range of topics. However, the extent ...

'Hardflow' algorithm could help generative AI produce high-quality outputs that obey strict requirements

MIT researchers have developed a new technique that helps generative artificial intelligence models find solutions to high-stakes problems. In these settings, a plausible answer is not enough: The output often must also satisfy ...

Bringing classical LDPC code design theory to quantum computers

Quantum error correction must detect and correct errors without directly reading the quantum information. Classical low-density parity check (LDPC) codes have a well-established design theory: by choosing how many checks ...

'Safe query space' lets AI fix SQL errors without starting over

"Find the best-selling product from last year." When an AI system attempts to answer a question like this by querying a company database, even a single reference to a nonexistent item can cause the query to fail. Until now, ...

Brain-inspired chaotic spiking backpropagation

Since it was discovered in the 1980s that learning in the rabbit brain utilizes chaos, this nonlinear and initially value-sensitive dynamical behavior has been increasingly recognized as integral to brain learning.

Q&A: How to train AI when you don't have enough data

Artificial intelligence excels at sorting through information and detecting patterns or trends. But these machine learning algorithms need to be trained with large amounts of data first.
