NettetData-splitting was used to test the accuracy of each taper function. PMS and the generalized PMS were the most accurate for both dob and volume, while the … NettetWhat Is Model Accuracy? AI accuracy is the percentage of correct classifications that a trained machine learning model achieves, i.e., the number of correct predictions divided by the total number of predictions across all classes. It is often abbreviated as ACC. ACC is reported as a value between [0,1] or [0, 100], depending on the chosen scale.
