In the below neural network, the 2nd layer is non trainable. when calculating gradient for the 1st layer, however, will the 2nd layer participate in? ...
Say I have a 2-layer neural network and I want to make the second layer non trainable. So I initiate these variables and train them. The problem ...
I want to draw the progress of the gradient descent. I start with the function "f" and the partial derivation of the function and start the gradient ...
I am supposed to implement gradient descent for linear regression. Here is the implementation: This works for a small dataset (25 elements) but whe ...
I am trying to implement some policy gradient training, similar to this. However, I would like to manipulate the rewards(like discounted future sum an ...
I have the following code in one part of my program: where x_conv is a Tensor (float32) of shape (384, 24, 1051) and x is a Tensor (float32) with s ...
I'm trying to estimate the two parameter of the following exponential decay. but the error(loss) is gradually increasing. I tried smaller learning_ra ...
I'm trying to implement a multivariable linear regression with gradient descent but when I try this: the output is so what I did wrong? I tried ...
I'm trying to compare between 2 models in order to learn about the behaviour of the gradients. Checking the gradient of the first model gives True ...
I am trying to fit a data set similar to gauss distribution with a simple neural network, but the effect is not good. The fitting result is always str ...

I'm trying to Implement linear regression in python using the following gradient decent formulas (Notice that these formulas are after partial derive) ...
I want to use JAX as a vehicle for gradient descent; however, I have a moderately large number of parameters and would prefer to pass them as a dictio ...
I have implemented logistic regression from scratch, however when I run the script the algorithm always predict the wrong label. I've tried changing t ...

Problem I am trying to build a simple gradient descent algorithm and plot it on a heatmap. I assume there are better ways to do this, but I have to ...
I'm trying to implement a Physical Informed Neural Network. The differential part in the loss did bring some improvment (compare to the classical neur ...
A brief description of my model: Consists of a single parameter X of dtype ComplexDouble and shape (20, 20, 20, 3). For reference, this must be co ...
I am coding a classifier neural network from scratch. It is not really learning and I believe that somewhere there is a gradient explosion/vanishing i ...
