WebApr 7, 2024 · Let’s look at the steps to perform backward feature elimination, which will help us to understand the technique. The first step is to train the model, using all the variables. You’ll of course not take the ID variable train the model as ID contains a unique value for each observation. So we’ll first train the model using the other three ... WebMar 19, 2024 · Now, lets assume the function f is a convolution between Input X and a Filter F. Input X is a 3x3 matrix and Filter F is a 2x2 matrix, as shown below: ... This gives us the forward pass! Let’s get to the Backward pass. As mentioned earlier, we get the loss gradient with respect to the Output O from the next layer as ∂L/∂O, during Backward ...
