Expected Calibration Error (ECE) measures the gap between predicted confidence levels and actual accuracy
calibration means: a model predicting 80% should be correct 80% of the time
A model predicting 80% should be correct 80% of the time
Brier score
Brier score measures mean squared error of probability predictions
word error rate (WER) measures: edit distance between predicted and reference transcriptions
WER measures the percentage of errors in transcription
Binomial proportion confidence interval
Binomial proportion confidence interval estimates success probability
log-loss / cross-entropy loss penalizes: confident wrong predictions more heavily
Cross-entropy loss penalizes confident wrong predictions more heavily
to normalize features: when features have different scales and you use distance-based methods
