5 days ago · AI in health should be regulated, but don’t forget about the algorithms, researchers say. In a recent commentary, a team from MIT, Equality AI, and Boston University highlights the gaps in regulation for AI models and non-AI algorithms in health care. December 12, …
New AI tool generates realistic satellite images of future flooding
Nov 25, 2024 · The AI-only method, in contrast, generated images of flooding in places where flooding is not physically possible. The team’s method is a proof-of-concept, meant to demonstrate a case in which generative AI models can generate realistic, trustworthy content when paired with a physics-based model.
Despite its impressive output, generative AI doesn’t have a …
Nov 5, 2024 · The researchers focused on a type of generative AI model known as a transformer, which forms the backbone of LLMs like GPT-4. Transformers are trained on a massive amount of language-based data to predict the next token in a sequence, such as the next word in …
Graph-based AI model maps the future of innovation
Nov 12, 2024 · The AI model found unexpected similarities between biological materials and “Symphony No. 9,” suggesting that both follow patterns of complexity. “Similar to how cells in biological materials interact in complex but organized ways to perform a function, Beethoven's 9th symphony arranges musical notes and themes to create a complex but ...
AI in health should be regulated, but don’t forget about the …
Dec 12, 2024 · “Clinical risk scores are less opaque than ‘AI’ algorithms in that they typically involve only a handful of variables linked in a simple model,” comments Isaac Kohane, chair of the Department of Biomedical Informatics at Harvard Medical School and editor-in-chief of NEJM AI. “Nonetheless, even these scores are only as good as the ...
Photonic processor could enable ultrafast AI computations with …
Dec 2, 2024 · Now that we have an end-to-end system that can run a neural network in optics, at a nanosecond time scale, we can start thinking at a higher level about applications and algorithms,” says Saumil Bandyopadhyay ’17, MEng ’18, PhD ’23, a visiting scientist in the Quantum Photonics and AI Group within the Research Laboratory of Electronics ...
MIT researchers develop an efficient way to train more reliable AI ...
Nov 22, 2024 · Reinforcement learning models, which underlie these AI decision-making systems, still often fail when faced with even small variations in the tasks they are trained to perform. In the case of traffic, a model might struggle to control a set of intersections with different speed limits, numbers of lanes, or traffic patterns.
What do we know about the economics of AI? - MIT News
Dec 6, 2024 · By contrast, in one paper, “The Simple Macroeconomics of AI,” published in the August issue of Economic Policy, Acemoglu estimates that over the next decade, AI will produce a “modest increase” in GDP between 1.1 to 1.6 percent over the next 10 years, with a roughly 0.05 percent annual gain in productivity.
AI simulation gives people a glimpse of their potential future self
Oct 1, 2024 · The AI system uses this information to create what the researchers call “future self memories” which provide a backstory the model pulls from when interacting with the user. For instance, the chatbot could talk about the highlights of someone’s future career or answer questions about how the user overcame a particular challenge.
MIT researchers introduce generative AI for databases
Jul 8, 2024 · Researchers from MIT and elsewhere developed an easy-to-use tool that enables someone to perform complicated statistical analyses on tabular data using just a few keystrokes. Their method combines probabilistic AI models with the programming language SQL to provide faster and more accurate results than other methods.
