Beyond the softmax probability

In classification, data scientists often use the softmax probability score as a notion of confidence about whether or not a predicted class (as indicated by Mathematical notation showing i as an element of the set containing integers 1 through K. ) is correct:

However, there are some caveats data scientists should be aware of, such as deterministic overconfidence and reliability degeneration in out-of-domain contexts.
