why are training test data more dissimilar what is separable why does it increase testing accuracy why would we have to have an aggregate classifier does putting training data together help improve test accuracy why does the noise in training data make it more sluggish? why is it difficult to combine multiple training data points into a single classifier? why is it important to reorder training data? what is the measure of linear regression why is it necessary to aggregate training data how to improve separability of training data what is the difference between aggregation and separability? why is the separability factor used in regression testing? what is the separability in classification what is the measure of separability what measures svm separability does merging feature vectors affect the separability of training data what measures separability how to measure separability and convergence what measures separability
