Researchers have used quantum physics and machine learning to quickly and accurately understand a mound of data – a technique, they say, could help extract meaning from gargantuan datasets.
Their method works on groundwater monitoring, and they’re trialling it on other fields like traffic management and medical imaging.
“Machine learning and artificial intelligence is a very powerful tool to look at datasets and extract features,” Dr Muhammad Usman, a quantum scientist at CSIRO, tells Cosmos.
A new study published in PNAS Nexus reveals that large language models, which are advanced artificial intelligence systems, demonstrate a tendency to present themselves in a favorable light when taking personality tests. This “social desirability bias” leads these models to score higher on traits generally seen as positive, such as extraversion and conscientiousness, and lower on traits often viewed negatively, like neuroticism.
The language systems seem to “know” when they are being tested and then try to look better than they might otherwise appear. This bias is consistent across various models, including GPT-4, Claude 3, Llama 3, and PaLM-2, with more recent and larger models showing an even stronger inclination towards socially desirable responses.
Large language models are increasingly used to simulate human behavior in research settings. They offer a potentially cost-effective and efficient way to collect data that would otherwise require human participants. Since these models are trained on vast amounts of text data generated by humans, they can often mimic human language and behavior with surprising accuracy. Understanding the potential biases of large language models is therefore important for researchers who are using or planning to use them in their studies.
New observational data from the James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to understand how planets and planetary systems form.
To date, more than 5,000 exoplanets have been confirmed around stars other than the Sun.
Many exoplanets are unlike any of the planets in the Solar System, making it difficult to guess their true natures.
A tool developed by Keele University researchers has been shown to help detect fake news with an impressive 99% level of accuracy, offering a vital resource in combating online misinformation.
The researchers Dr. Uchenna Ani, Dr. Sangeeta Sangeeta, and Dr. Patricia Asowo-Ayobode from Keele’s School of Computer Science and Mathematics, used a number of different machine learning techniques to develop their model, which can scan news content to give a judgment of whether a news source is trustworthy and genuine or not.
The method developed by the researchers uses an “ensemble voting” technique, which combines the predictions of multiple different machine learning models to give an overall score.
Shares of Denver-based software provider Palantir rose nearly 27% on February 4 following 2024 fourth quarter results featuring faster-than-expected growth and an optimistic forecast for the current quarter and the year 2025.
Having risen 368% in the last year and sporting a price-earnings ratio of 516, according to the Wall Street Journal, do shares of Palantir have more upside? If Wall Street analysts are right, the stock is about 26% too high. However, what matters most for the future of Palantir’s stock is whether the company can keep beating expectations and raising guidance.
That could happen – especially if Palantir – which counts Peter Thiel among the company’s early investors – can harness artificial intelligence to make its defense and commercial customers better off.
Palantir fourth quarter performance and prospects.
In recent years, the debate concerning the ontology of mind and body has been structured around an opposition between monistic, physicalist ontologies (both reductive and non-reductive) and some form of dualism (both of property types and of kinds of substance). This, however, has not always been the case. In the early twentieth century, a monistic, but non-physicalist, ontology
Neutral monism was also considered a serious contender, favoured especially by theorists working within what James characterises as the radical empiricist tradition. This paper outlines a new version of this third species of position in the mind-body debate. Unlike its predecessors, however, this version of neutral monism is motivated not by primarily epistemological considerations, but on the basis of recent developments on the ontology of properties. It is argued that, if one adopts the \.

NMR spectroscopy and imaging show that dendrites in a solid-state Li battery are formed from Li plating on the electrode and Li+ reduction at solid electrolyte grain boundaries, with an interlapped stalled growth period.
