The Importance of Understanding Backpropagation in Deep Learning Education

Summary
The article argues for the importance of understanding backpropagation in deep learning, even though modern frameworks automate it. The author explains that implementing backprop from scratch in Stanford's CS231n course helps students build intuition about neural networks, debug effectively, and understand what's happening under the hood. The article addresses common student complaints about having to write backward passes manually and makes the case that this foundational knowledge is crucial for becoming a proficient deep learning practitioner rather than just a framework user.
Key quotes
· 4 pulledWhy do we have to write the backward pass when frameworks in the real world, such as TensorFlow, compute them for you automatically?
We intentionally designed the programming assignments to include explicit calculations involved in backpropagation on the lowest level.
The students had to implement the forward and the backward pass of each layer in raw numpy.
This is seemingly a perfectly sensible appeal - if you're never going to write backward passes once the class is over.
