Simon Brendle: Minimal surfaces and the isoperimetric inequality
Abstract: The isoperimetric inequality has a long history in the geometry. In this lecture, we will discuss how the isoperimetric inequality can be generalized to submanifolds in Euclidean space. As a special case, we obtain a sharp isoperimetric inequality for minimal submanifolds of codimension at most 2, thereby answering a question going back to work of Carleman. The proof of that inequality is inspired by, but does not actually use, optimal transport

    The variance equation for linear combinatiions of random variables applies to dot products. Fast transforms (FFT,WHT) are fixed sets of dot products. ReLU is a switch. f(x)=x is connect, f(x)=0 is disconnect. A ReLU net is a switched system of dot products the collapses to a simple matrix for a particular input. You can have inside out nets with fixed dot products and adjustable parametric activation functions. Random projection first (eg. sign flips) and final transform as pseudo-readout layer.
