Largest Text-To-Speech AI Model Yet Shows ‘Emergent Abilities’

Devin Coldeway reports via TechCrunch: Researchers at Amazon have trained the largest ever text-to-speech model yet, which they claim exhibits “emergent” qualities improving its ability to speak even complex sentences naturally. The breakthrough could be what the technology needs to escape the uncanny valley. These models were always going to grow and improve, but the researchers specifically hoped to see the kind of leap in ability that we observed once language models got past a certain size. For reasons unknown to us, once LLMs grow past a certain point, they start being way more robust and versatile, able to perform tasks they weren’t trained to. That is not to say they are gaining sentience or anything, just that past a certain point their performance on certain conversational AI tasks hockey sticks. The team at Amazon AGI — no secret what they’re aiming at — thought the same might happen as text-to-speech models grew as well, and their research suggests this is in fact the case.

The new model is called Big Adaptive Streamable TTS with Emergent abilities, which they have contorted into the abbreviation BASE TTS. The largest version of the model uses 100,000 hours of public domain speech, 90% of which is in English, the remainder in German, Dutch and Spanish. At 980 million parameters, BASE-large appears to be the biggest model in this category. They also trained 400M- and 150M-parameter models based on 10,000 and 1,000 hours of audio respectively, for comparison — the idea being, if one of these models shows emergent behaviors but another doesn’t, you have a range for where those behaviors begin to emerge. As it turns out, the medium-sized model showed the jump in capability the team was looking for, not necessarily in ordinary speech quality (it is reviewed better but only by a couple points) but in the set of emergent abilities they observed and measured. Here are examples of tricky text mentioned in the paper:

– Compound nouns: The Beckhams decided to rent a charming stone-built quaint countryside holiday cottage.
– Emotions: “Oh my gosh! Are we really going to the Maldives? That’s unbelievable!” Jennie squealed, bouncing on her toes with uncontained glee.
– Foreign words: “Mr. Henry, renowned for his mise en place, orchestrated a seven-course meal, each dish a piece de resistance.
– Paralinguistics (i.e. readable non-words): “Shh, Lucy, shhh, we mustn’t wake your baby brother,” Tom whispered, as they tiptoed past the nursery.
– Punctuations: She received an odd text from her brother: ‘Emergency @ home; call ASAP! Mom & Dad are worried… #familymatters.’
– Questions: But the Brexit question remains: After all the trials and tribulations, will the ministers find the answers in time?
-Syntactic complexities: The movie that De Moya who was recently awarded the lifetime achievement award starred in 2022 was a box-office hit, despite the mixed reviews. You can read more examples of these difficult texts being spoken naturally here.

F-Zero Courses From a Dead Nintendo Satellite Service Restored Using VHS and AI

An anonymous reader quotes a report from Ars Technica: Nintendo’s Satellaview, a Japan-only satellite add-on for the Super Famicom, is a rich target for preservationists because it was the home to some of the most ephemeral games ever released. That includes a host of content for Nintendo’s own games, including F-Zero. That influential Super Nintendo (Super Famicom in Japan) racing title was the subject of eight weekly broadcasts sent to subscribing Japanese homes in 1996 and 1997, some with live “Soundlink” CD-quality music and voiceovers. When live game broadcasts were finished, the memory cartridges used to store game data would report themselves as empty, even though they technically were not. Keeping that same 1MB memory cartridge in the system when another broadcast started would overwrite that data, and there were no rebroadcasts.

As reported by Matthew Green at Press the Buttons (along with Did You Know Gaming’s informative video), data from some untouched memory cartridges was found and used to re-create some of the content. Some courses, part of a multi-week “Grand Prix 2” event, have never been found, despite a $5,000 bounty offering and extensive effort. And yet, remarkably, the 10 courses in those later broadcasts were reverse-engineered, using a VHS recording, machine learning tools, and some manual pixel-by-pixel re-creation. The results are “north of 99.9% accurate,” according to those who crafted it and exist now as a mod you can patch onto an existing F-Zero ROM. […] Their work means that, 25 years later, a moment in gaming that was nearly lost to time and various corporate currents has been, if not entirely restored, brought as close as is humanly (and machine-ably) possible to what it once was.

Early Blood Test To Predict Dementia Is Step Closer As Biological Markets Identified

Researchers have made significant progress toward developing a blood test that can predict the risk of dementia up to 15 years before clinical diagnosis. The Guardian reports: Hopes for the test were raised after scientists discovered biological markers for the condition in blood samples collected from more than 50,000 healthy volunteers enrolled in the UK Biobank project. Analysis of the blood identified patterns of four proteins that predicted the onset of dementia in general, and Alzheimer’s disease and vascular dementia specifically, in older age. When combined with more conventional risk factors such as age, sex, education and genetic susceptibility, the protein profiles allowed researchers to predict dementia with an estimated 90% accuracy nearly 15 years before people received clinical confirmation of the disease.

For the latest study, blood samples from 52,645 UK adults without dementia were collected and frozen between 2006 and 2010 and analyzed 10 to 15 years later. More than 1,400 participants went on to develop dementia. Using artificial intelligence, the researchers looked for connections between nearly 1,500 blood proteins and developing dementia years later. Writing in Nature Aging, they describe how four proteins, Gfap, Nefl, Gdf15 and Ltbp2, were present in unusual levels among those who developed all-cause dementia, Alzheimer’s disease or vascular dementia. Higher levels of the proteins were warning signs of disease. Inflammation in the brain can trigger cells called astrocytes to over-produce Gfap, a known biomarker for Alzheimer’s. People with raised Gfap were more than twice as likely to develop dementia than those with lower levels.

Another blood protein, Nefl, is linked to nerve fibre damage, while higher than normal Gdf15 can occur after damage to the brain’s blood vessels. Rising levels of Gfap and Ltbp2 was highly specific for dementia rather than other brain diseases, the scientists found, with changes occurring at least 10 years before people received a dementia diagnosis. The researchers are speaking to companies to develop the test but said the cost, currently at several hundred pounds, would need to come down to make it viable.

Amazon Hides Cheaper Items With Faster Delivery, Lawsuit Alleges

A class-action lawsuit alleges (PDF) that Amazon manipulates its platform through a biased algorithm to favor the “Buy Box” for items that generate higher fees for Amazon, often leading consumers to overpay for products that could be obtained cheaper and just as quickly from other sellers on the platform. Ars Technica reports: The lawsuit claims that a biased algorithm drives Amazon’s “Buy Box,” which appears on an item’s page and prompts shoppers to “Buy Now” or “Add to Cart.” According to customers suing, nearly 98 percent of Amazon sales are of items featured in the Buy Box, because customers allegedly “reasonably” believe that featured items offer the best deal on the platform.

“But they are often wrong,” the complaint said, claiming that instead, Amazon features items from its own retailers and sellers that participate in Fulfillment By Amazon (FBA), both of which pay Amazon higher fees and gain secret perks like appearing in the Buy Box. “The result is that consumers routinely overpay for items that are available at lower prices from other sellers on Amazonâ”not because consumers don’t care about price, or because they’re making informed purchasing decisions, but because Amazon has chosen to display the offers for which it will earn the highest fees,” the complaint said.

Authorities in the US and the European Union have investigated Amazon’s allegedly anticompetitive Buy Box algorithm, confirming that it’s “favored FBA sellers since at least 2016,” the complaint said. In 2021, Amazon was fined more than $1 billion by the Italian Competition Authority over these unfair practices, and in 2022, the European Commission ordered Amazon to “apply equal treatment to all sellers when deciding what to feature in the Buy Box.” These investigations served as the first public notice that Amazon’s Buy Box couldn’t be trusted, customers suing said. Amazon claimed that the algorithm was fixed in 2020, but so far, Amazon does not appear to have addressed all concerns over its Buy Box algorithm. As of 2023, European regulators have continued pushing Amazon “to take further action to remedy its Buy Box bias in their respective jurisdictions,” the customers’ complaint said.

Computer Simulations of Atlantic Ocean Currents Finds Collapse Could Happen in Our Lifetime

An anonymous reader shared this report from the Associated Press:

An abrupt shutdown of Atlantic Ocean currents that could put large parts of Europe in a deep freeze is looking a bit more likely and closer than before as a new complex computer simulation finds a “cliff-like” tipping point looming in the future. A long-worried nightmare scenario, triggered by Greenland’s ice sheet melting from global warming, still is at least decades away if not longer, but maybe not the centuries that it once seemed, a new study in Friday’s Science Advances finds.

The study, the first to use complex simulations and include multiple factors, uses a key measurement to track the strength of vital overall ocean circulation, which is slowing. A collapse of the current — called the Atlantic Meridional Overturning Circulation or AMOC — would change weather worldwide because it means a shutdown of one of key the climate and ocean forces of the planet. It would plunge northwestern European temperatures by 9 to 27 degrees (5 to 15 degrees Celsius) over the decades, extend Arctic ice much farther south, turn up the heat even more in the Southern Hemisphere, change global rainfall patterns and disrupt the Amazon, the study said. Other scientists said it would be a catastrophe that could cause worldwide food and water shortages.

“We are moving closer (to the collapse), but we we’re not sure how much closer,” said study lead author Rene van Westen, a climate scientist and oceanographer at Utrecht University in the Netherlands. “We are heading towards a tipping point.” When this global weather calamity — grossly fictionalized in the movie “The Day After Tomorrow” — may happen is “the million-dollar question, which we unfortunately can’t answer at the moment,” van Westen said. He said it’s likely a century away but still could happen in his lifetime. He just turned 30.

“It also depends on the rate of climate change we are inducing as humanity,” van Westen said.

San Francisco Mob Lights Driverless Waymo Car on Fire

Last night in San Francisco’s Chinatown, “A person jumped on the hood of a Waymo driverless taxi and smashed its windshield…” reports the Verge, “generating applause before a crowd formed around the car and covered it in spray paint, breaking its windows, and ultimately set it on fire.”

The fire department arrived minutes later, according to a report in The Autopian, but by then flames had already fully engulfed the car…. Waymo representative Sandy Karp told The Verge via email that the fully autonomous car “was not transporting any riders” when it was attacked and fireworks were tossed inside the car, sparking the flames…

The fire takes place against the backdrop of simmering tension between San Francisco residents and automated vehicle operators… Just last week, a Waymo car struck a cyclist who had reportedly been following behind a truck turning across its path.

The “burnt-out husk of the electric Waymo Jaguar” appears in a video posted on YouTube, according to the article. “Another set of videos posted by software developer Michael Vendi gives a view into the scene as it played out and the fire grew.”

San Francisco’s 49ers play in the Super Bowl this afteroon, so last night’s celebrations for Chinese New Year could be followed by additional celebrations tonight. Police Chief Bill Scott is already urging residents to behave responsibly. “Please don’t light anything on fire.”

California Bill Would Require Computer Science For High School Graduation

At a press conference last week, a California Assemblymember joined the State Superintendent of Public Instruction in announcing a bill that, if passed, would require every public high school to teach computer science. (And establish CS as a high school graduation requirement by the 2030-31 school year.)

Long-time Slashdot reader theodp says he noticed posters with CS-education advocacy charts and stats “copied verbatim” from the tech giant-backed nonprofit Code.org. (And “a California Dept. of Education news release also echoed Code.org K-12 CS advocacy factoids.”)

The announcement came less than two weeks after Code.org CEO Hadi Partovi — whose goal is to make CS a HS graduation requirement in all 50 states by 2030 — was a keynote speaker at the Association of California School Administrators Superintendents’ Symposium. Even back in an October 20 Facebook post, [California state assemblyman] Berman noted he’d partnered with Code.org on legislation in the past and hinted that something big was in the works on the K-12 CS education front for California. “I had the chance to attend Code.org’s 10th anniversary celebration and chat with their founder, Hadi Partovi, as well as CS advocate Aloe Blacc. They’ve done amazing work expanding access to computer science education… and I’ve been proud to partner with them on legislation to do that in CA. More to come!”
