Introduction to Convolutional Neural Networks for Self Driving Cars

We have an image, and we want our network to say it's an image with a cat in it. It doesn't really matter where the cat is, it's still an image with a cat. If our network has to learn about kittens in the left corner, and about kittens in the right corner independently, that's a lot of work that it has to do. How about we telling it, instead explicitly, that objects and images are largely the same whether they're on the left or on the right of the picture. That's what's called translation invariance.
