Deep learning specialization, course 4, week 1 [Post #28, Day 69]

It's 23:30 and I just struggled through the conv_forward code block in course 4, week 1, assignment 1. I had to go back to the lecture videos, I had to draw all the matrices out on my grid paper, I had to print statement just about everything in the function, but I figured it out! I learned if I start swearing, getting frustrated, and have neural pain, it is a good thing because I am facing a challenge and learning.

I had some help in the forum with figuring out vert_start and horiz_start, I had to multiply by stride. I also wasn't clear on if stride works in both horizontal and vertical directions, I thought maybe it only was applied in the horizontal direction, but no, it gets applied in both directions.

I am learning how to code a convolutional neural network (ConvNet) from scratch. If I had to keep track of matrices and their dimensions before, it has been taken up a major notch now.
