MIT neuroscientists have performed the most rigorous testing yet of computational models that mimic the brain’s visual cortex.
Using their current best model of the brain’s visual neural network, the researchers designed a new way to precisely control individual neurons and populations of neurons in the middle of that network. In an...

Your ability to recognize objects is remarkable. If you see a cup under unusual lighting or from unexpected directions, there’s a good chance that your brain will still compute that it is a cup. Such precise object recognition is one holy grail for AI developers, such as those improving self-driving car navigation. While modeling primate object recognition in the visual cortex has revolutionized artificial visual recognition...

Abstract:
Theoretical and empirical results in the neural networks literature demonstrate that effective learning at a real-world scale requires changes to synaptic weights that approximate the gradient of a global loss function. For neuroscientists, this means that the brain must have mechanisms...

Robots are very useful. They are used in industrial applications, manufacturing, and assembly. Now, a new system will teach them to do something more refined. Something like molding sticky rice into that edible little thing called sushi.
A group of MIT researchers, namely Yunzhu Li, Jiajun Wu, Russ Tedrake, Joshua B. Tenenbaum, and Antonio Torralba, have developed a system that improves a robot’s ability to mold certain...

Title: Recurrent computations during visual object perception—investigating within and beyond the primate ventral stream
Abstract
Recurrent circuits are ubiquitous in the primate ventral stream, that supports core object recognition — primate’s ability to rapidly categorize objects. While...

PhD student Sarah Schwettmann explains how the study of visual perception can translate students’ creativity across domains.
by Connie Blaszczyk | Center for Art, Science, and Technology
Computational neuroscientist Sarah Schwettmann is one of three instructors behind the cross-disciplinary course 9.S52/9.S916 (Vision in Art and Neuroscience), which introduces students to core concepts in visual perception through the lenses of art and...

Together, deep learning and symbolic reasoning create a program that learns in a remarkably humanlike way.
by Will Knight
Excerpt: "Over the decades since the inception of artificial intelligence, research in the field has fallen into two main camps. The “symbolists” have sought to build intelligent machines by coding in logical rules and representations of the world. The “connectionists” have sought to construct artificial neural networks,...

Abstract: When trained to minimize reconstruction error, a linear autoencoder (LAE) learns the subspace spanned by the top principal directions but cannot learn the principal directions themselves. In this talk, I'll explain how this observation became the focus of a project on representation...

Researchers combine statistical and symbolic artificial intelligence techniques to speed learning and improve transparency.

A child who has never seen a pink elephant can still describe one — unlike a computer. “The computer learns from data,” says Jiajun Wu, a PhD student at MIT. “The ability to generalize and recognize something you’ve never seen before — a pink elephant — is very hard for machines.”...

Machine Learning and Artificial Intelligence (AI) will impact several sectors in a big way in the next ten years, especially healthcare, with several jobs to be affected and many other interesting jobs to emerge, an expert told Gulf Times.
“Healthcare is an area where machine learning will have a huge impact," explained Dr Antonio Torralba, a professor of electrical engineering and computer science at the Massachusetts Institute of Technology (...

Abstract: Recent progress in computer vision has led to new unresolved questions about their emergent properties. Understanding the emergent behaviour of computer vision algorithms can fuel the engineering of computer vision and help understand biological intelligence. In this talk, I will discuss...

Abstract: The brain’s memory systems are like time machines for thought: they transport sensory experiences from the past to the present, to guide our current decisions and actions. Memories have been classified into long-term, stored for time intervals of days, months, or years, and short-term,...

McGovern Institute researchers find that the brain starts to register gender and age before recognizing a face.
Sabbi Lall | McGovern Institute for Brain Research
Our brains are incredibly good at processing faces, and even have specific regions specialized for this function. But what face dimensions are we observing? Do we observe general properties first, then look at the details? Or are dimensions such as gender or other identity details...
