In this pytorch code: I want y[0]’s gradient to consist 2 parts: loss backward to y[0] itself. y[0] is used to calculate y[1], so it should have the part of y[1]’s gradient. but when I run this code, there is only part 1 in y[0]’s gradient. So how to make y[0]’s gradient to have all 2 parts? edit: the output

Gradient exploding problem in a graph neural network
I have a gradient exploding problem which I couldn’t solve after trying for several days. I implemented a custom message passing graph neural network in TensorFlow which is used to predict a continuous value from graph data. Each graph is associated with one target value. Each node of a graph is represented by a node attribute vector, and the edges
Why is my conical/angle gradient image distorted?
I’m currently trying to create a conical gradient, and it kind of works. However, it doesn’t look quite right and I can’t wrap my hand around to why: The line that goes up from the center is slightly angled to the right and at the bottom there is a visible (not too noticable) line. Code is as follows: Oh, and
The gradient (2d) search function returns None. What is the problem?
I have a function that should return a gradient. But when calculating the gradient at a specific point, I get None. Object classes: t1-function, t2-function, t3-None (I want to get a two-dimensional point) Please tell me how to change this line to make it work? PS. I understand that there are built-in methods for calculating the gradient. But this is
Compute the gradient of the SVM loss function
I am trying to implement the SVM loss function and its gradient. I found some example projects that implement these two, but I could not figure out how they can use the loss function when computing the gradient. Here is the formula of loss function: What I cannot understand is that how can I use the loss function’s result while
How to plot a gradient color line in matplotlib?
To state it in a general form, I’m looking for a way to join several points with a gradient color line using matplotlib, and I’m not finding it anywhere. To be more specific, I’m plotting a 2D random walk with a one color line. But, as the points have a relevant sequence, I would like to look at the plot
