Road signs "driving" you crazy?

You also might be wondering what all this CNN stuff is. Don't worry, I can explain A CNN is a type of neural network (read my other articles to learn the basics) that is particularly good with image classification. CNNs are used for computer vision because they are great at detecting patterns in images, such as lines, circles and other shapes and patterns. A CNN uses convolutional layers, which essentially learn filters that can detect patterns in an image. For example, a filter could detect vertical lines, or it could detect horizontal lines. These filters "convolve" over an image, going in little 3x3 (or whatever the size of the filter) chunks to get the dot product of said 3x3 chunk.
