If you want to understand how deep learning can create protein fingerprints, Bronstein suggests looking at digital cameras from the early 2000s. Even Michael Bronsteinâs earlier method, which let neural networks recognize a single 3D shape bent into different poses, fits within it. The data is four-dimensional, he said, âso we have a perfect use case for neural networks that have this gauge equivariance.â. 04/22/2017 ∙ by Federico Monti, et al. These âconvolutional neural networksâ (CNNs) have proved surprisingly adept at learning patterns in two-dimensional data â especially in computer vision tasks like recognizing handwritten words and objects in digital images. 12 min read. Luckily, physicists since Einstein have dealt with the same problem and found a solution: gauge equivariance. âThis is one of the things that I find really marvelous: We just started with this engineering problem, and as we started improving our systems, we gradually unraveled more and more connections.â.

Risi Kondor, a former physicist who now studies equivariant neural networks, said the potential scientific applications of gauge CNNs may be more important than their uses in AI. corr... He is also a principal engineer at Intel Perceptual Computing. Physical theories that describe the world, like Albert Einsteinâs general theory of relativity and the Standard Model of particle physics, exhibit a property called âgauge equivariance.â This means that quantities in the world and their relationships donât depend on arbitrary frames of reference (or âgaugesâ); they remain consistent whether an observer is moving or standing still, and no matter how far apart the numbers are on a ruler. Now this idea is allowing computers to detect features in curved and higher-dimensional space. 0 âAnd they figured out how to do it.â. He has previously served as Principal Engineer at Intel Perceptual Computing. For example, the network could automatically recognize that a 3D shape bent into two different poses â like a human figure standing up and a human figure lifting one leg â were instances of the same object, rather than two completely different objects.

Cohen, Weiler and Welling encoded gauge equivariance â the ultimate âfree lunchâ â into their convolutional neural network in 2019. The catch is that while any arbitrary gauge can be used in an initial orientation, the conversion of other gauges into that frame of reference must preserve the underlying pattern â just as converting the speed of light from meters per second into miles per hour must preserve the underlying physical quantity.
