Sperm whales rattle off a series of rapid-fire clicks that researchers have named “codas.” Each coda consists of between three and 40 clicks. In addition to changing the number of clicks they make in quick succession, whales often speed up or slow down the tempo of each coda—researchers call this “rubato.” Sometimes, they add an extra “click” at the end of a coda, which scientists call “ornamentation.”

In the end, the team identified 156 distinct codas, each with its own rubato, ornamentation, tempo and rhythm. On their own, these codas may simply be meaningless sounds. But when combined, they could add up to something akin to syllables, words or even sentences.

Just like Tesla, the JiYue 1 uses a camera-based, vision-only design for its autonomous driving. It is one of several competitors to FSD available in China.

BYD’s new EV platform with improved motors and charging speeds to arrive in Sea Lion 7 EV in weeks.

BYD officially launched its new Sea Lion 7, a mid-size smart electric SUV poised to rival Tesla’s top-selling Model Y. Starting at 189,800 yuan ($26,250), the BYD Sea Lion 7 is the first EV based on its new e-Platform 3.0 Evo.

After unveiling the Sea Lion 07 at the Guangzhou Auto Show in November, BYD officially launched the new electric SUV last week.

BYD said it was its first “medium-sized urban smart electric SUV.” It’s also the first EV based on BYD’s new e-Platform 3.0 Evo. The new EV platform is an upgrade from the e-Platform 3.0 with improved charging and powertrain capability.

NVIDIA today announced that it will accelerate quantum computing efforts at national supercomputing centers around the world with the open-source NVIDIA CUDA-Q™ platform.

But MIT scientists now claim to have cracked this problem by creating “a treasure trove” of natural language “abstractions” that could lead to more powerful AI models. Abstractions turn complex subjects into high-level characterizations and omit non-important information — which could help chatbots reason, learn, perceive, and represent knowledge just like humans.

Currently, scientists argue that LLMs have difficulty abstracting information in a human-like way. However, they have organized natural language abstractions into three libraries in the hope that they will gain greater contextual awareness and give more human-like responses.

The scientists detailed their findings in three papers published on the arXiv pre-print server Oct. 30 2023, Dec. 13 2023 and Feb. 28. The first library, called the “Library Induction from Language Observations” (LILO) synthesizes, compresses, and documents computer code. The second, named “Action Domain Acquisition” (Ada) covers AI sequential decision making. The final framework, dubbed “Language-Guided Abstraction” (LGA), helps robots better understand environments and plan their movements.

As people age, their brains do, too. But if a brain ages prematurely, there is potential for age-related diseases such as mild cognitive impairment, dementia, or Parkinson’s disease. If “brain age” could be easily calculated, then premature brain aging could be addressed before serious health problems occur.

Researchers from Drexel University’s Creativity Research Lab have developed an artificial intelligence technique that can effectively estimate an individual’s brain age based on electroencephalogram (EEG) brain scans. The technology could help to make early, regular screening for degenerative brain diseases more accessible. The work is published in the journal Frontiers in Neuroergonomics.

Led by John Kounios, Ph.D., professor in Drexel’s College of Arts and Sciences and Creativity Research Lab director, the research team used a type of artificial intelligence called machine learning to estimate an individual’s brain age similar to the way one might guess another person’s age based on their physical appearance.
