Large language models (LLMs), the most renowned of which is ChatGPT, have become increasingly better at processing and generating human language over the past few years. The extent to which these models emulate the neural processes supporting language processing by the human brain, however, has yet to be fully elucidated.

Researchers at Columbia University and Feinstein Institutes for Medical Research Northwell Health recently carried out a study investigating the similarities between LLM representations on neural responses...

In “Star Trek: The Next Generation,” Captain Picard and the crew of the U.S.S. Enterprise leverage the Holodeck, an empty room capable of generating 3D environments, of preparing for missions and entertaining them, simulating everything from lush jungles to the London of Sherlock Holmes.

Deeply immersive and fully interactive, Holodeck-created environments are infinitely customizable, using nothing but language; the crew has only to ask the computer to generate an environment, and that space appears in the Holodeck.

Today, virtual interactive environments are also used to train robots prior to real-world deployment in a process called “Sim2...

A small team of AI researchers at Microsoft reports that the company’s Orca-Math small language model outperforms other, larger models on standardized math tests. The group has published a paper on the arXiv preprint server describing their testing of Orca-Math on the Grade School Math 8K (GSM8K) benchmark and how it fared compared to well-known LLMs.

Many popular LLMs such as ChatGPT are known for their impressive conversational skills—less well known is that most of them can also solve math word problems. AI researchers have tested their abilities at such tasks by pitting them against the GSM8K, a dataset of 8,500 grade-school math word problems that require multistep reasoning to solve, along with their correct answers.

In this new study, th...

New AI Model can Predict Human Lifespan, researchers say. They want to make sure it’s used for good

Researchers have created an Artificial Intelligence tool that uses sequences of life events—such as health history, education, job and income—to predict everything from a person’s personality to their mortality.

Built using transformer models, which power large language models (LLMs) like ChatGPT, the new tool, life2vec, is trained on a data set pulled from the entire population of Denmark—6 million people. The data set was made available only to the researchers by the Danish government.

The tool the researchers built based on this complex set of data is capable of predicting the future, including the lifespan of individuals, with an accuracy that exceeds state-of-the-art models...
