Teaching an AI to draw "Me".
Here is a gif animation I created from just a few snapshots of an AI as it learns to paint a picture of me. The first picture it outputs is just a grey square 200 by 200 pixels. Each attempt is compared to a picture of me and the AI is told how close it is to looking like me. I let the AI try 500,000 times. It took 3 hours. Considering that the AI only has 123 neurons, it did a pretty good job. It would need to have at least 4,000 neurons to paint an exact copy of the photo, but that is not the point. I just wanted to get a feel for how it learns.
I didn't write any code. I used a Javas script AI that runs in a browser. The browser page lets you change a few lines of code to increase the depth and size of the neural networks and see how it relates to the speed and quality of the learning process,
