Back Propogation

fastai - lesson five

Posted on September 12, 2019

Here are some of my notes from the fifth lesson of the Fast AI course.

Back Propogation

This lesson took a deep-dive into the inner workings of back propogation, used in previous lessons. I’m still trying to get my mind wrapped around the power of this step-wise method to exhibit such emergent behavior. The FastAI and PyTorch libaries were used to good effect to demonstrate the functioning internals.

Lesson 5 - Example

Neural Nets

With that knowledge, the instructor took another look at various neural nets, demonstrating the use of backpropogation within.
