Researchers have developed a new way to automatically detect hate speech on social media platforms more accurately and consistently using a new multi-task learning (MTL) model; a type of machine learning model that works across multiple datasets.Researchers have developed a new way to automatically detect hate speech on social media platforms more accurately and consistently using a new multi-task learning (MTL) model; a type of machine learning model that works across multiple datasets.Internet[#item_full_content]

OpenAI, the artificial intelligence company that developed the popular ChatGPT chatbot and the text-to-art program Dall-E, is at a crossroads. On Oct. 2, 2024, it announced that it had obtained US$6.6 billion in new funding from investors and that the business was worth an estimated $157 billion—making it only the second startup ever to be valued at over $100 billion.OpenAI, the artificial intelligence company that developed the popular ChatGPT chatbot and the text-to-art program Dall-E, is at a crossroads.

A patient recovering from a limb amputation won’t use a prostheses that isn’t comfortable. A person rehabbing from a stroke won’t use a robotic exoskeleton if the mobility it grants doesn’t allow them to perform everyday activities. And a diabetes patient won’t use an insulin pump that doesn’t deliver the appropriate dosage of medicine to control their blood sugar.A patient recovering from a limb amputation won’t use a prostheses that isn’t comfortable.

Concern about misuse of artificial intelligence has led political leaders to consider regulating the emerging technology in ways that could limit access to AI models’ inner workings. But researchers at a group of leading universities, including Princeton, caution that such restrictions are likely to do more harm than good.Concern about misuse of artificial intelligence has led political leaders to consider regulating the emerging technology in ways that could limit access to AI models’ inner workings.

A team of AI researchers from Peking University, Kuaishou Technology, and Beijing University of Posts and Telecommunications, has developed a new AI model called Pyramid Flow, that can be used to generate virtual hi-resolution (768p) video imagery. The group has written a paper describing how they built their model, its attributes and uses to which it might be put and have posted it on the arXiv preprint server.A team of AI researchers from Peking University, Kuaishou Technology, and Beijing University of Posts and Telecommunications, has developed a new AI model called Pyramid Flow, that can be used to generate virtual hi-resolution (768p) video imagery.

Ka-band metasurface antennas, with their low-cost, low-profile design and superior beam-steering capabilities, show significant potential in the field of satellite communications. However, the constraints of limited satellite resources and significant atmospheric losses at Ka-band frequencies require these antennas to achieve wide-angle beam scanning capabilities and high antenna gain, adding considerable complexity to their design.Ka-band metasurface antennas, with their low-cost, low-profile design and superior beam-steering capabilities, show significant potential in the field of satellite communications.
