For simplicity, let's assume we want to solve a regression problem, where we have one independent variable and one dependent variable, which we want to predict. Let's also assume that there is a nonlinear relationship between the independent and…

I'm trying to make a neural network in pytorch that picks the parameters of a nonlinear function, the radius and (x,y) center of a circle in the example below, based on a sample of values from the nonlinear function. More concretely, the neural…

There are many relationships that cannot be described by a "static function" in N dimensions because relationships of the type I am talking about have an iterative element when one of the inputs of a function is its previous output. Here is a…

I have a simple curve fitting problem in hand. I wrote some code in PyTorch as follows: class MyDatasetV1(torch.utils.data.Dataset): def __init__(self, dataset): # Initialize a dataset assert isinstance(dataset, list), '"dataset" must…
