At the same time, Taco Cohen and his colleagues in Amsterdam were beginning to approach the same problem from the opposite direction. Creating feature maps is possible because of translation equivariance: The neural network “assumes” that the same feature can appear anywhere in the 2D plane and is able to recognize a vertical edge as a vertical edge whether it’s in the upper right corner or the lower left. These features are passed up to other layers in the network, which perform additional convolutions and extract higher-level features, like eyes, tails or triangular ears. Michael received his PhD from the Technion (Israel Institute of Technology) in 2007. ∙ But for physicists, it’s crucial to ensure that a neural network won’t misidentify a force field or particle trajectory because of its particular orientation. share, Drug repositioning is an attractive cost-efficient strategy for the 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 — just as converting the speed of light from meters per second into miles per hour must preserve the underlying physical quantity. ), Meanwhile, gauge CNNs are gaining traction among physicists like Cranmer, who plans to put them to work on data from simulations of subatomic particle interactions. 0 ∙ Michael Bronstein. 12/17/2010 ∙ by Roee Litman, et al.

We are excited to announce the first Israeli workshop on geometric deep learning (iGDL) that will take place on August 2nd, 2020 2 PM-6 PM (Israel timezone). 0 “Physics, of course, has been quite successful at that.”, Equivariance (or “covariance,” the term that physicists prefer) is an assumption that physicists since Einstein have relied on to generalize their models.

As Cohen put it, “Both fields are concerned with making observations and then building models to predict future observations.” Crucially, he noted, both fields seek models not of individual things — it’s no good having one description of hydrogen atoms and another of upside-down hydrogen atoms — but of general categories of things. ∙ Rather, he was interested in what he thought was a practical engineering problem: data efficiency, or how to train neural networks with fewer examples than the thousands or millions that they often required. ∙ 07/19/2013 ∙ by Michael M.

Qualcomm, a chip manufacturer which recently hired Cohen and Welling and acquired a startup they built incorporating their early work in equivariant neural networks, is now planning to apply the theory of gauge CNNs to develop improved computer vision applications, like a drone that can “see” in 360 degrees at once.

They did this by placing mathematical constraints on what the neural network could “see” in the data via its convolutions; only gauge-equivariant patterns were passed up through the network’s layers. ∙ Cohen, Weiler and Welling encoded gauge equivariance — the ultimate “free lunch” — into their convolutional neural network in 2019.
