Data Mining - (Test|Expected|Generalization) Error

Thomas Bayes

About

Test error is the prediction error that we incur on new data. The test error is actually how well we'll do on future data the model hasn't seen.

The test error is the average error that results from using a statistical learning method to predict the response on a new observation, one that was not used in training the method.

Estimation

Test error can be estimated :

Data Mining - Training Error

Training error is the prediction error we get applying the model to the same data from which we trained. Training error is much easier to compute than test error. Train error is often lower than test...

Statistics Learning - Prediction Error (Training versus Test)

The Prediction Error tries to represent the noise through the concept of training error versus test error. We fit our model to the training set. We take our model, and then we apply it to new data that...
