Performance metrics for regression problems Here comes another fun part: metrics that are used to evaluate the performance of regression models. Unlike classification, regression provides output in the form of a numeric value, not a class, so you can’t use classification accuracy for evaluation. ...
Calculate some standard regression evaluation metrics of predictive performanceLuis Torgo
Create a rocmetrics object to evaluate the performance of a classification model using receiver operating characteristic (ROC) curves or other performance metrics. rocmetrics supports both binary and multiclass problems. For each class, rocmetrics computes performance metrics for a one-versus-all ROC ...

Aim/Purpose The aim of this study was to analyze various performance metrics and approaches to their classification. The main goal of the study was to develop a new typology that will help to advance knowledge of metrics and facilitate their use in machine learning regression algorithms Background...
1.3.3.1 Inference performance metrics An inference performance can be evaluated based on the inference accuracy, generalization performance, precision, recall, and F1 score. • Accuracy This is a common metric used to show the inference performance on the trained neural network model, and is a ra...
