OpenAI came up with a remedy for “hallucinations” in neural networks

Published

One of the problems of modern neural networks is their “hallucinations”. This is the name given to data that does not correspond to the real state of affairs, but neural networks generate them along with true facts. And now OpenAI announced that it has come up with a new method for training artificial intelligence models that will help to cope with the “hallucinations” of AI.

Even the most modern models are prone to false conclusions – they tend to invent facts in moments of uncertainty. These hallucinations are especially critical in areas that require multi-step reasoning, since one logical error is enough to make the whole result wrong.”, write the OpenAI researchers in the report.

The idea of ​​the new method is to change the motivation system for AI. In other words, it is proposed to reward the neural network for each correct step of reasoning, instead of the reward being given for the final correct answer. This will allow the neural network to be more accurate and check the facts.

According to the researchers, the detection and elimination of logical errors in the model, or hallucinations, is an important step towards creating a consistent AGI.

He also clarified that the company has already opened access to the accompanying data set of 800,000 labels that were used to train the neural network as part of the study.

At the same time, the problem is far from being solved, and experts say that the company has not yet opened all the information on this study. Thus, the risk of AI “hallucinations” remains relevant for the time being.

Only in 2025 will the iPhone have what the Samsung

Next year's iPhone 17 will feature an anti-glare display that is more scratch-resistant than the Apple Ceramic Shield found on iPhone 15 models.

Chinese insider Instant Digital said that the iPhone 17's protective glass will have an “ultra-hard anti-reflective layer” that is “more scratch-resistant than you think.” According to the source, the coating equipment has just been transferred to China's supply chain, but it will not be used for the iPhone 16 series.

Ceramic Shield is the marketing name for a glass-ceramic material developed by Corning in collaboration with Apple. Apple says the iPhone 15's ceramic screen is “stronger than any smartphone glass.” Apple touted glass with a ceramic coating that improves drop resistance by 4 times compared to the iPhone 11.

Samsung recently unveiled its latest Galaxy S24 Ultra, which comes with a Gorilla Glass Armor display, also developed by Corning. According to Corning, the Armor panel reduces glare by 75% compared to a regular glass surface and is resistant to micro-scratches that can occur over time on competing glass panels. Corning also claims the panels are more than 4 times more scratch resistant than competing aluminosilicate safety glass.

It is unclear whether Apple plans to use Gorilla Glass Armor for the iPhone 17.

Instant Digital accurately reported on the yellow iPhone 14, spatial video recording capabilities on the iPhone 15 Pro, and Apple Watch Series 9 features.

Honor Magic6 Pro beats Samsung Galaxy S24 Ultra Huawei Mate

DxOMark specialists today published a review of the main camera of the Honor Magic6 Pro smartphone. Its capabilities were rated at 158 ​​points, and this is a new record: in DxOMark tests, Honor Magic6 Pro surpassed Samsung Galaxy S24 Ultra, Huawei Mate 60 Pro+, iPhone 15 Pro Max and almost all other top camera phones (the Xiaomi 14 Ultra test has not yet been published).

Traditionally, testers note the pros and cons. The former include bright and natural colors in both photos and videos, good detail at different zoom modes, fast and accurate autofocus, large depth of field in scenes with objects in several planes, wide dynamic range and accurate exposure. Cons: unnatural reproduction of details in photos, videos and when zooming, differences in frame sharpness when recording videos on the go, artifacts when shooting high-contrast scenes, blurred images in portraits in very low light.

The Honor Magic6 Pro performed outstandingly in DxOMark's camera tests, taking first place in our rankings and ahead of devices such as the Huawei Mate 60 Pro, Oppo Find X7 Ultra and Apple iPhone 15 Pro Max. It performed excellently in almost all areas of testing, showing no real weaknesses. It's also a noticeable improvement over its predecessor, the Magic5 Pro.,” said DxOMark.

Long-lasting radio signals from sunspots were recorded for the first time

Long lasting radio signals from sunspots were recorded for the first

A group of scientists have discovered long-lasting radio signals over sunspots. The radio signals were detected at an altitude of about 40,000 kilometers above the sunspot. This is the first ever observation of such radio signals on the Sun; previous long-lasting radio signals have been detected on other planets or stars.

“This radio emission from sunspots represents the first detection of its kind,” said lead author Xiji Yu of the New Jersey Institute of Technology.

The discovery of long-lasting radio signals from the Sun will help scientists better understand our star and study the processes underlying radio signals, as well as processes occurring on distant stars. The Sun regularly emits short radio bursts that can last from a few minutes to several hours.

However, the radio burst observed by scientists lasted more than a week, significantly longer than normal short radio bursts. The researchers made observations using 27 radio telescopes in New Mexico, combined into the Very Large Array (VLA).

In addition to their duration, radio bursts have spectra and polarization features similar to auroras on Earth, caused by the interaction of solar particles with the planet's magnetic field. On Earth, as well as on Jupiter and Saturn, auroras occur as a result of the interaction of solar particles with a magnetic field, which attracts and accelerates the particles towards the poles, where the magnetic field lines converge.

As solar particles accelerate toward the poles, they emit intense radio signals at frequencies of several hundred kilohertz. When they reach the planet's atmosphere, interacting with the atoms of the atmosphere, an “aurora” occurs.

Scientists analyzed the data to study the characteristics and nature of long-lasting radio bursts detected above sunspots. The results showed that radio bursts likely result from processes similar to the formation of auroras. The energetic electrons become trapped in the magnetic field created by the sunspot. Once in the field, the particles are accelerated towards the sunspot, where the magnetic field lines converge, creating radio signals.

Unlike the “auuroras” on Earth, Jupiter and Saturn, radio bursts over sunspots occur at much higher frequencies, approximately one million kilohertz, a significant difference from the usual hundreds of thousands of kilohertz at which auroras occur on Earth.

“This is a direct consequence of the fact that the magnetic field of a sunspot is thousands of times stronger than the Earth’s magnetic field,” Yu explained.

Over the next weeks and months, the team will re-examine other solar radio bursts to determine whether they are similar to the long-lasting bursts detected by the VLA.

“We are in an excellent position to study the sources of such radio bursts thanks to NASA's growing fleet of heliophysics missions. For example, Solar Dynamics Observatory [SDO] “is constantly monitoring active regions of the Sun that may be leading to this phenomenon,” said heliophysicist Nachimuthuk Gopalswamy of NASA's Goddard Space Flight Center.
