LLM-Deflate: Extracting LLMs into Datasets

Large Language Models compress massive amounts of training data into their parameters. This compression is lossy but highly effective—billions of parameters can encode the essential patterns from terabytes of text. However, what’s less obvious is that this process can be reversed: we can systematically extract structured datasets from trained models that reflect their internal knowledge representation. I’ve been working on this problem, and the results are promising. We’ve successfully applied

Your Samsung phone and watch could soon warn you of Alzheimer’s disease

The Galaxy maker elaborated on this approach in its post: Recalling and repeating short sentences can evaluate short-term memory-related brain regions, while assessing speech fluency and accuracy reveals the state of language ability. Likewise, the regularity and variety of app and messaging use, along with call frequency, can offer insights into social networks and the brain’s executive functions. In short, the study demonstrated that brain regions responsible for language and short-term memo

AI models know when they're being tested - and change their behavior, research shows

pressureUA/iStock/Getty Images Plus via Getty Images Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Several frontier AI models show signs of scheming. Anti-scheming training reduced misbehavior in some models. Models know they're being tested, which complicates results. New joint safety testing from UK-based nonprofit Apollo Research and OpenAI set out to reduce secretive behaviors like scheming in AI models. What researchers found could complicate promising ap

Google releases VaultGemma, its first privacy-preserving LLM

The companies seeking to build larger AI models have been increasingly stymied by a lack of high-quality training data. As tech firms scour the web for more data to feed their models, they could increasingly rely on potentially sensitive user data. A team at Google Research is exploring new techniques to make the resulting large language models (LLMs) less likely to "memorize" any of that content. LLMs have non-deterministic outputs, meaning you can't exactly predict what they'll say. While the

How does air pollution impact your brain?

Image credit: Ionut Stefan We’ve known for some time that air pollution is bad for human health. However, the focus was mostly on the lungs, and to some extent, the heart. After all, airborne pollutants are inhaled through the lungs and can reach the heart through the bloodstream, so it’s not surprising these take the brunt of the damage. But somewhere along the way, it became somewhat mainstream to consider how air pollution might affects brains too. What I found surprising was the recency of

Pilot union urges FAA to reject Rainmaker’s drone cloud-seeding plan

Rainmaker Technology’s bid to deploy cloud-seeding flares on small drones is being met by resistance from the airline pilots union, which has urged the Federal Aviation Administration to consider denying the startup’s request unless it meets stricter safety guidelines. The Federal Aviation Administration’s decision will signal how the regulator views weather-modification by unmanned aerial systems going forward. Rainmaker’s bet on small drones hangs in the balance.

UK launches Project Octopus, thousands of interceptor drones to Ukraine

UK defence secretary John Healey has outlined new plans to send thousands of interceptor missiles to Ukraine every month, with the Ukrainian-developed UAV to be shared with the UK to help in the fight against Russia. Speaking at DSEI, Healey outlined ‘Project Octopus’, a new partnership between the UK and Ukraine. Under the project, Ukraine would share technology developed for a new interceptor drone that had proved highly effective against Iranian-made, Russian-deployed Shahed one-way attack d

Chronic Insomnia Is Bad for the Brain. Like, Really Bad

If you’re a chronic insomniac, you might experience faster declines in memory and thinking skills than your better-sleeping fellows. In other words, your brain might age faster. In a study published Wednesday in the journal Neurology, researchers revealed that people with chronic insomnia, described as having trouble sleeping at least three days a week for three months or more, were significantly more likely to develop mild cognitive impairment or dementia than their healthy counterparts. “Ins

After Ukrainian testing, drone-detection radar doubles range with simple software patch

As part of its unprovoked invasion, Russia has been firing massed waves of drones and missiles into Ukraine for years, though the tempo has been raised dramatically in recent months. Barrages of 700-plus drones now regularly attack Ukraine during overnight raids. Russia also appears to have upped the ante dramatically by sending at least 19 drones into Poland last night, some of which were shot down by NATO forces. Many of these drones are Shahed/Geran types built with technology imported from

Garmin’s Top Training Features, Explained

So, you’ve got a shiny new Garmin watch. Maybe it’s the sleek Vivoactive 6, the run-focused Forerunner 970, or (my favorite) the ultimate all-arounder Fēnix 8. You’re tracking your steps, sleep, floors climbed, calories burned—all the standard, self-explanatory stuff. But then you dig a little deeper into the menus, and it hits you: A tidal wave of data. Training Status? Acute Load? Body Battery? What the hell do these things mean? Don’t let it spike your heart rate (which the watch also tracks

This Is the First Time Scientists Have Seen Decisionmaking in a Brain

Neuroscientists from around the world have worked in parallel to map, for the first time, the entire brain activity of mice while they were making decisions. This achievement involved using electrodes inserted inside the brain to simultaneously record the activity of more than half a million neurons distributed across 95 percent of the rodents’ brain volume. Thanks to the image obtained, the researchers were able to confirm an already theorized architecture of thought: that there is no single r

An Anatomically Correct Replica of the Human Brain, Knitted by a Psychiatrist

Our brains dic­tate our every move. They’re the ones who spur us to study hard, so we can make some­thing of our­selves, in order to bet­ter our com­mu­ni­ties. They name our babies, choose our clothes, decide what we’re hun­gry for. They make and break laws, orga­nize protests, frit­ter away hours on social media, and give us the green light to binge watch a bunch of dumb shows when we could be read­ing War and Peace. They also plant the seeds for Fitz­car­ral­do-like cre­ative endeav­ors t

A history of metaphorical brain talk in psychiatry

We first turn to Adolf Meyer, the most influential psychiatrist in the US over the first 3rd of the 20th century [27]. It should be recalled that until World War II, American psychiatry was a rather small profession, largely composed of superintendents of mental hospitals who largely had a biologically orientation to their work. In 1907, while the director of the New York Psychiatric Institute, Meyer wrote about his concerns of the narrow views that US physicians would typically take in their ap

Lab Mice Exposed to Microplastics Show Signs of Dementia

Image by Getty / Futurism Neuroscience/Brain Science Should you be worried that your brain probably contains enough plastic to fashion a disposable spoon? Yes, new research suggests: you should. In a new study published in the journal Environmental Research Communications, researchers found that mice which were regularly exposed to microplastics in their diet developed symptoms of Alzheimer's disease, the most common form of dementia, in less than a single month. The mice were genetically mo

Scientists Intrigued by Pill That May Heal Brain After Stroke or Brain Injury

Image by Getty / Futurism Neuroscience/Brain Science Researchers are working on a pill that could allow patients' brains to recover from a traumatic injury or stroke, defying conventional thinking that the brain cannot regenerate following such a traumatic event. As the New York Times reports, researchers previously discovered a gene that codes for a receptor called CCR5, which has been found in experiments to suppress lab mice's ability to learn and remember.

How big are our embeddings now and why?

Sep 1 2025 #embeddings #openai #anthropic #huggingface #dimensionality A few years ago, I wrote a paper on embeddings. At the time, I wrote that 200-300 dimension embeddings were fairly common in industry, and that adding more dimensions during training would create diminishing returns for the effectiveness of your downstream tasks (classification, recommendation, semantic search, topic modeling, etc.) I wrote the paper to be resilient to changes in the industry since it focuses on fundamenta

30 minutes with a stranger

30m 0s A few months ago, I was taking the subway to work when a 16-year-old boy slipped on the subway platform and hit his chin on the ground. He stumbled onto the train and stood next to me. I kept my earbuds in and tried to convince myself this wasn’t my problem. Then out of the corner of my eye I saw that he’d split open his chin; blood and tears were gushing down his face. I looked around the train for someone else to help—maybe someone who works with kids. No one even looked up. So I grabb

MIT Study Finds AI Use Reprograms the Brain, Leading to Cognitive Decline

By Nicolas Hulscher, MPH A new MIT study titled, Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task, has found that using ChatGPT to help write essays leads to long-term cognitive harm—measurable through EEG brain scans. Students who repeatedly relied on ChatGPT showed weakened neural connectivity, impaired memory recall, and diminished sense of ownership over their own writing. While the AI-generated content often scored well, the brains beh
