A two-score softmax probability · formula reference
Softmax normalizes scores; this alone does not prove probabilities are calibrated to real-world frequencies.
Formula
Softmax normalizes scores; this alone does not prove probabilities are calibrated to real-world frequencies.
p₁ = exp(s₁)/(exp(s₁)+exp(s₂))
Worked example
Softmax scores are (-2,1). Calculate the probability assigned to the first score. Round the final result to 4 decimal places if needed.
Use the stable equivalent 1/[1+exp(3)].
0.0474
Prerequisites and checking
Algebra and the topic definitions. Keep units and rounding consistent. State the model conditions before applying the formula.
