Week_2_practice lab1

in section 5 of the lab, where the recommender system builds using the vectorized cost function and we are running gradient descent, where are the final/optimized values of the X, W, and b stored/returned to be used later for making a prediction. I do not see what steps give us those values. In section 6, I see that the original variables are used but I don’t understand at which step their updated values are assigned to them.

Hi @Basira_Daqiq

In this cell of code

The weights are updated by first compute the gradient and second it’s update these weights
