How to interpret the output
Subtracts the largest log weight before exponentiation and normalizes the resulting weights. Outputs sum to approximately one; very small relative weights may underflow to zero. Inputs are natural logarithms, not raw probabilities. Does not validate a statistical model. Source checked 14 November 2026.
