Topic modeling is a well-established technique for exploring text corpora. Conventional topic models (e.g., LDA) represent topics as bags of words that often require "reading the tea leaves" to interpret; additionally, they offer users minimal semantic control over topics. To tackle these issues, we introduce TopicGPT, a prompt-based framework that uses large language models (LLMs) to uncover latent topics within a provided text collection. TopicGPT produces topics that align better with human categorizations compared to competing methods: for example, it achieves a harmonic mean purity of 0.74 against human-annotated Wikipedia topics compared to 0.64 for the strongest baseline. Its topics are also more interpretable, dispensing with ambiguous bags of words in favor of topics with natural language labels and associated free-form descriptions. Moreover, the framework is highly adaptable, allowing users to specify constraints and modify topics without the need for model retraining. TopicGPT can be further extended to hierarchical topical modeling, enabling users to explore topics at various levels of granularity. By streamlining access to high-quality and interpretable topics, TopicGPT represents a compelling, human-centered approach to topic modeling.

A Tesla owner charges his vehicle in April 2021 at a charging station in Topeka, Kan.. Tesla reported 273 crashes involving partially automated driving systems, according to statistics released by U.S. safety regulators on Wednesday. A Tesla owner charges his vehicle in April 2021 at a charging station in Topeka, Kan.. Tesla reported 273 crashes involving partially automated driving systems, according to statistics released by U.S. safety regulators on Wednesday. Automakers reported nearly 400 crashes of vehicles with partially automated driver-assist systems, including 273 involving Teslas, according to statistics released Wednesday by U.S. safety regulators. The National Highway Traffic Safety Administration cautioned against using the numbers to compare automakers, saying it didn't weight them by the number of vehicles from each manufacturer that use the systems, or how many miles those vehicles traveled. Automakers reported crashes from July of last year through May 15 under an order from the agency, which is examining such crashes broadly for the first time.

Tax laws, for example, don't currently take automated workers into account. While human employees contribute payroll and income taxes, an automated "employee" doesn't, Abbott noted. Governments could lose out on quite a bit of income tax as AI becomes more prevalent and possibly displaces more human workers. Granted, that argument only works if displaced employees don't find other jobs. Abbott predicted that that may happen as AI becomes smarter at a rate that outpaces people's ability to learn new skills or find job training.

Atima Lui was in primary school when she first learned that "nude" is not universal. Now 30, she still recalls playing with a white friend's makeup and struggling to find colours that complemented her rich skin tone. "I would try to put [her makeup] on and it would just make me look like a clown," says Lui, who is of Sudanese and African-American descent. "I think back to growing up and how my mother barely wore makeup. Now I know it's because makeup just wasn't made for her."

Kansas WebFile, the state's full service online tax filing portal, has a new feature. "We were the first state to implement a chatbot within a tax system, and we're the first state to offer a chatbot of any nature," Nolan Jones general manager of Kansas Information Consortium said. Agent Kay, the state's 24/7 official chatbot, can help you file your tax return online. "And it provides them a better experience with dealing with the government and some like taxes they don't want to be in there very long. They just want to get their filing done," Jones said.

SpaceX's CRS-15 Dragon cargo resupply ship has been attached to the International Space Station. the spacecraft rendezvoused with the orbiting outpost in the early-morning hours of July 2, 2018, and is expected to remain berthed for about a month. Capture took place at 6:54 a.m. EDT (10:54 GMT) by the 57.7-foot (17.6-meter) Canadian-built robotic Canadarm2, which was under the control of Expedition 56 NASA astronauts Ricky Arnold and Drew Feustel at the robotics work station in the station's cupola window. The vehicle was grappled while the station was flying 256 miles (412 kilometers) over Quebec City. "Looking forward to some really exciting weeks ahead as we unload the science and get started on some great experiments," Arnold said.

Artificial intelligence, robots, and automation are rising in importance in many areas. As noted in the recent book, "The Future of Work: Robots, AI, and Automation," there are exciting advances in finance, transportation, national defense, smart cities, and health care, among other areas. Businesses are developing solutions that improve the efficiency and effectiveness of their operations and using these tools to improve the way their firms function. Yet there also are concerns about the impact of these developments on jobs and personal privacy. A Pew Research Center national survey revealed considerable unease about emerging trends.

These are the horrifying photos from the heyday of the Eugenics movement that the world wants to forget. Before the atrocities of Nazi Germany, eugenics - the system of measuring human traits, seeking out the desirable ones and cutting out the undesirable ones - was once practised the world over. In the decades following the 1859 publication of Charles Darwin's'On the Origin of Species', a veritable craze for eugenics spread through Britain, the United States and Europe. Bruno Beger was a German racial anthropologist who worked for the Ahnenerbe, a project in Nazi Germany to research the archaeological and cultural history of the Aryan race. In this image taken in 1938, Dr Beger is measuring a Tibetan woman's head to demonstrate what he believed were the'inferior' characteristics of her race Advocates of eugenics made significant advances during the early twentieth century - and claimed that'undesirable' genetic traits such as dwarfism, deafness and even minor defects like a cleft palate needed to be wiped out of the gene pool.

To understand the war on the global elites that Steve Bannon and Donald Trump claim to have unleashed, think of an epic battle between Bruce Wayne and Lex Luthor. The fabulously wealthy corporate titan and criminal mastermind, Luthor is motivated by self-enrichment and megalomania. Originally drawn as a man with a full head of red hair, Luthor's hatred of Superman and Batman may lay partly in a complicated hair story variously interpreted as an artistic mistake, Superboy's fault, or merely male pattern baldness. As a child he was either an abused boy growing up in poverty and bootstrapping his way to wealth, or as the resentful son of a wealthy and domineering father. Luthor blames Superman for his failures to help humankind and the chances he has passed up to do the right thing.

Will A.I. make our government smarter and more responsive – or is that the last step towards the end of privacy? As chief scientist of U.S. Government Accountability Office, Tim Persons conceives its vision for advanced data analytics. Learn about the promise and challenges around government A.I. and what those portend for private sector companies. Dr. David A.
