I tried writing a neural network from scratch

Описание: In this video I show what I learned while writing a neural network from scratch and training it to recognise hand drawn digits.
Number 1 lesson I learned is triple check your inputs!

The video series I followed to learn most of this was by ‪@TheCodingTrain‬ and I can highly recommend it:    • 10.1: Introduction to Neural Networks - Th...  

Chapters:
0:00 - Why to learn machine learning
0:30 - What I will be teaching the neural network
0:45 - How I learned to write the neural network
1:00 - What a neural network is and how it works
2:00 - What a single perceptron can learn
3:00 - The XOR problem for neural networks
4:45 - Explaining the MNIST dataset to recognise hand drawn digits
5:45 - Training the NeuralNetwork to recognise hand drawn digits
6:10 - Testing the neural network for the first time
6:30 - Debugging the failed test
7:45 - Explaining Convolutional Neural Networks
8:40 - Training and testing digit recognition with convolutional neural networks
9:55 - Further debugging the failed test with the CNN
10:20 - Finding the bug
11:05 - Testing with the bug fix

I can also recommend the videos of 3Blue1Brown on convolutions from which I stole some of the animations:    • But what is a convolution?
