High-level overview of the STEGO architecture at train and prediction steps

Segmented Images, No Labeled Data: Improved unsupervised learning for semantic segmentation

Training a model to separate the objects in a picture typically requires labeled images for best results. Recent work upped the ante for training without labels.
Some results from the 2022 AI Strategy Report survey by MIT Sloan Management Review.

AI as Officemate: Workers benefit from AI-powered assistance and tools.

Many workers benefit from AI in the office without knowing it, a new study found. MIT Sloan Management Review and Boston Consulting Group surveyed employees on their use of AI in their day-to-day work. Their findings...
Model that defeats KataGo, an open source Go-playing system

Champion Model Is No Go: Adversarial AI Beats Master KataGo Algorithm

A new algorithm defeated a championship-winning Go model using moves that even a middling human player could counter. Researchers trained a model to defeat KataGo, an open source Go-playing system that has beaten top human players.
Different x-rays and CT scans displayed

AI Sees Race in X-Rays

Researchers from Emory University, MIT, Purdue University, and other institutions found that deep learning systems trained to interpret x-rays and CT scans also were able to identify their subjects as Asian, Black, or White.
Neural networks generating novel views of a 3D scene based on existing pictures

3D Scene Synthesis for the Real World

Researchers have used neural networks to generate novel views of a 3D scene based on existing pictures plus the positions and angles of the cameras that took them. In practice, though, you may not know the precise camera
Model identifying erroneous labels in popular datasets

Labeling Errors Everywhere

Key machine learning datasets are riddled with mistakes. Several benchmark datasets are shot through with incorrect labels. On average, 3.4 percent of examples in 10 commonly used datasets are mislabeled and the detrimental impact of such errors rises with model size.
A generative adversarial network (GAN)

Image Generation Transformed

A recent generative adversarial network (GAN) produced more coherent images using modified transformers that replaced fully connected layers with convolutional layers. A new GAN achieved a similar end using transformers in their original form.
Data related to a diagnostic advice received from a machine learning model vs a human expert

Would Your Doctor Take AI’s Advice?

Some doctors don’t trust a second opinion when it comes from an AI system. A team at MIT and Regensburg University investigated how physicians responded to diagnostic advice they received from a machine learning model versus a human expert.
Different data related to the phenomenon called underspecification

Facing Failure to Generalize

The same models trained on the same data may show the same performance in the lab, and yet respond very differently to data they haven’t seen before. New work finds this inconsistency to be pervasive.
Data related to a language model that predicts mutations that would enable infectious viruses

The Language of Viruses

A neural network learned to read the genes of viruses as though they were text. That could enable researchers to page ahead for potentially dangerous mutations. Researchers at MIT trained a language model to predict mutations that would enable infectious viruses to become even more virulent.
Graphs and examples of Network dissection technique

What One Neuron Knows

How does a convolutional neural network recognize a photo of a ski resort? New research shows that it bases its classification on specific neurons that recognize snow, mountains, trees, and houses.
Information and components of a battery

Getting a Charge From AI

Machine learning is helping to design energy cells that charge faster and last longer. Battery developers are using ML algorithms to devise new chemicals, components, and charging techniques faster than traditional techniques allow.
Data and examples related to a new technique to detect portions of an image

The Telltale Artifact

Deepfakes have gone mainstream, allowing celebrities to star in commercials without setting foot in a film studio. A new method helps determine whether such endorsements — and other images produced by generative adversarial networks — are authentic.
Images and data related to a t-shirt that tricks a variety of object detection models into failing to spot people

Hidden in Plain Sight

With the rise of AI-driven surveillance, anonymity is in fashion. Researchers are working on clothing that evades face recognition systems and designed a t-shirt that tricks a variety of object detection models into failing to spot people.
Africa map and location sign with letters AI over it

AI in Regions Rich and Poor

Companies in Africa and the Middle East are building AI capacity in very different ways, a new study found. AI is growing fast in both regions despite shortages of talent and data.
