The problem

Have you ever played the game Fizz buzz? Don't worry if you haven't. The following is a simple explanation of what the game is about.

Note

As per Wikipedia, Fizz buzz [1] is a group word game for children that teaches them about division. Players take turns to count incrementally. Any number divisible [2] by three is replaced by the word fizz and any number divisible by five is replaced by the word buzz. Numbers divisible by both become fizz buzz.

Fizz buzz has been used in a fun example by Joel Grus, one of the research engineers at the Allen Institute of Artificial Intelligence (AI2), while writing a blog post [3] on TensorFlow. Although this particular example doesn't solve any practical problems, the blog post got quite a lot of traction and it is fun to see how a neural network learns to find a mathematical pattern from a number stream.
