Missing calculation of gradient descent derivatives on Coursera Deep Learning specialization

February 20, 2018


For some reasons Andrew Ng didn't show how to obtain derivatives in back-prop. He showed final results only. I didn't feel good about that. It wasn't a nice feeling to do not understand something from the very beginning. That's why I performed necessary calculation on my own.

Would you like to see how it's done?

Here you'll find results of my own experiments inspired by programming assignment from first course of Coursera Deep Learning specialization - cat detector.

Initial play with hyperparameters and - later - more systematic search led me to much better accuracy and interesting observations.
