Make sure to check out the previous video first, it covers gradient descent and the first part of how we train our network, • Neural Networks From Zero: Gradient Descent
Here is the code to go with the video: https://github.com/ejmejm/Iris-Neural...
This video covers backpropogation and how it works intuitively as well as mathematically. After we finish training our network, we test the accuracy for the final results.
Thanks for watching!
