Started studying neural networks. It is necessary to predict the outcome of a football match (P1 / X / P2). At the output of the network, I get the value 0..1 as the probability of an outcome, but how to connect this result with a certain outcome?

3 outputs and softmax

So it's better:
1. (binary output) One of the two teams had an advantage over the other.
2. (binary output) This advantage was enough to win (otherwise - a draw).
So worse:
1. (binary output) Team A wins.
2. (binary output) Team B wins.
Draw = not(a) and not(b).
The first option will have greater prediction accuracy and the corresponding network will be easier to train. You can check and make sure.
