Exercise

Output layer using shared layer

Now that you've looked up how "strong" each team is, subtract the team strengths to determine which team is expected to win the game.

This is a bit like the seeds that the tournament committee uses, which are also a measure of team strength. But rather than using seed differences to predict score differences, you'll use the difference of your own team strength model to predict score differences.

The subtract layer will combine the weights from the two layers by subtracting them.
