Jan 2, 2025 · 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.
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 ...
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 …
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.
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.
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.
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 ...
Researchers reduce bias in AI models while preserving or …
Dec 11, 2024 · MIT researchers developed an AI debiasing technique that improves the fairness of a machine-learning model by boosting its performance for subgroups that are underrepresented in its training data, while maintaining its overall accuracy.
Explained: Generative AI | MIT News | Massachusetts Institute of …
Nov 9, 2023 · Before the generative AI boom of the past few years, when people talked about AI, typically they were talking about machine-learning models that can learn to make a prediction based on data. For instance, such models are trained, using millions of examples, to predict whether a certain X-ray shows signs of a tumor or if a particular borrower is ...
