You are the AI. You have scored three possibilities — cat, dog, bird. How do you turn raw scores into a confident choice, and into a probability you can defend?
Every score is raised as a power of e — that keeps the weights positive and makes gaps dramatic — then each weight is divided by the total, so the three shares add to exactly 1. In symbols: p(i) = ezi/T ÷ Σ ezj/T, and the Σ is just the three-term sum you can see above it.
