Witryna3 sty 2024 · 1 Answer Sorted by: 1 Since your function has period 2π we can focus on [0,2π]. Since it's piecewise linear, it's possible to express it as a mini ReLU network on [0,2π] given by: trapezoid (x) = 1 - relu (x-1.5π)/0.5π - relu (0.5π-x)/0.5π Thus, we can code the whole function in Pytorch like so: WitrynaGaussianNLLLoss.
