WebIn mathematics (in particular, functional analysis), convolution is a mathematical operation on two functions (f and g) that produces a third function that expresses how the shape of one is modified by the other.The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two …

If A is a n × m matrix, an example of a linear operator, then we know that ky −Axk2 is minimized when x = [A0A]−1A0y. We want to solve such problems for linear operators between more general spaces. To do so, we need to generalize “transpose” Web22 de nov. de 2024 · Recently, Sedghi et al.[] has provided a principled approach to exactly compute the singular values of convolution layers. However, the method proposed in [] is still computationally expensive prohibiting its use during the training of deep networks.
