Analytics: For supervised learning classifiers, define these goodness of fit measures: (a) accuracy and (b) loss function.
Homework Answers
a) accuracy - It means how accurate are the expected values in comparison with the actual values . Thereby indicating how correct the initial assessment is.
b) Loss function- It is typically the difference between the expected and actual values. It implies the correctness of the entire estimation and execution of process.
