Computer Science and Artificial Intelligence Laboratory (CSAIL)

To develop a superior AI assistant, begin by simulating the unpredictable actions of humans.

In an effort to improve AI systems and their ability to collaborate with humans, scientists are trying to better understand human decision-making, including its suboptimal aspects, and model it in AI. A model for human or AI agent behaviour, developed by researchers at MIT and the University of Washington, takes into account an agent’s unknown…

Researchers from MIT have made significant progress in enhancing the automatic understanding in AI models.

As AI models become increasingly integrated into various sectors, understanding how they function is crucial. By interpreting the mechanisms underlying these models, we can audit them for safety and biases, potentially deepening our understanding of intelligence. Researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have been working to automate this interpretation process, specifically…

A novel artificial intelligence approach accurately interprets ambiguity in medical imaging.

Artificial intelligence (AI) tools have great potential in the field of biomedicine, particularly in the process of segmentation or annotating the pixels of an important structure in a medical image. Segmentation is critical for the identification of possible diseases or anomalies in body organs or cells. However, the challenge lies in the variability of the…

An improved, speedier method to inhibit an AI chatbot from providing harmful responses.

While artificial intelligence (AI) chatbots like ChatGPT are capable of a variety of tasks, concerns have been raised about their potential to generate unsafe or inappropriate responses. To mitigate these risks, AI labs use a safeguarding method called "red-teaming". In this process, human testers aim to elicit undesirable responses from the AI, informing its development…

A fresh approach to artificial intelligence quantifies uncertainty in medical imaging.

Segmentation, a practice in biomedicine whereby pixels from a significant structure in a medical image are annotated, can be aided by artificial intelligence (AI) models. However, these models often give only one solution, while the problem of medical image segmentation usually requires a range of interpretations. For instance, multiple human experts may have different perspectives…

An improved, quicker method to stop an AI chatbot from providing harmful responses.

Artificial Intelligence (AI) Chatbots like OpenAI's ChatGPT are capable of performing tasks from generating code to writing article summaries. However, they can also potentially provide information that could be harmful. To prevent this from happening, developers use a process called red-teaming, where human testers write prompts to identify unsafe responses in the model. Nevertheless, this…

New AI technique encapsulates ambiguity in healthcare pictures.

In the realm of biomedicine, segmentation is a process where certain areas or pixels within a medical image, such as an organ or cell, are annotated or highlighted. This primarily assists clinicians in pinpointing areas showing signs of diseases or abnormalities. However, there is often a gray area since different experts can have differing interpretations…

A more efficient and improved method to inhibit AI chatbots from producing harmful responses.

AI chatbots like ChatGPT, trained on vast amounts of text from billions of websites, have a broad potential output which includes harmful or toxic material, or even leaking personal information. To maintain safety standards, large language models typically undergo a process known as red-teaming, where human testers use prompts to elicit and manage unsafe outputs.…

A fresh approach to artificial intelligence measures ambiguity in health-related imagery.

Biomedical segmentation pertains to marking pixels from significant structures in a medical image like cells or organs which is crucial for disease diagnosis and treatment. Generally, a single answer is provided by most artificial intelligence (AI) models while making these annotations, but such a process is not always straightforward. In a recent paper, Marianne Rakic, an…

An improved and speedier method to stop AI chatbot from providing harmful responses.

AI chatbots pose unique safety risks—while they can write computer programs or provide useful summaries of articles, they can also potentially generate harmful or even illegal instructions, including how to build a bomb. To address such risks, companies typically use a process called red-teaming. Human testers aim to generate unsafe or toxic content from AI…

A new technique in artificial intelligence accurately recognizes uncertainty in health imagery.

A research team from MIT, the Broad Institute of MIT and Harvard, and Massachusetts General Hospital has developed an artificial intelligence (AI) tool, named Tyche, that presents multiple plausible interpretations of medical images, highlighting potentially important and varied insights. This tool aims to address the often complex ambiguity in medical image interpretation where different experts…

A quicker, more efficient method to safeguard against an AI chatbot providing harmful or inappropriate responses.

To counter unsafe responses from chatbots, companies often use a process called red-teaming, in which human testers write prompts designed to elicit such responses so the artificial intelligence (AI) can be trained to avoid them. However, since it is impossible for human testers to cover every potential toxic prompt, MIT researchers developed a technique utilizing…
