"[SOLVED] Performance Operator Evaluation - Mathematics / Derivation"
Would someone be able to enlighten me on the mathematics behind some of the performance evaluation metrics and/or point me to a nice resource/website? Specifically, if I am using a Performance (Classification) Operator, I would like to know how the following are derived:
- Accuracy: specifcially, the +/- %
- The difference between the mikro percentages and the given percentages
- Classification Error vs. Relative Error vs. Root Mean Squared Error
- How/Why the +/- % for Accuracy, Weighted Mean Recall, and Classification Error are different and why
