Prediction modeling is often classified under the unsupervised machine learning methods. False True 2. k-means algorithm is a part of prediction data mining method. False True 3. The multi split methodology partitions data into exactly two mutually exclusive subsets called training set and test set. True 6. 4. A data set is imbalanced when the distribution of different classes in the input variables are significantly dissimilar. True False 5. Overfitting is the notion of making the model too specific to the training data to capture not only the signal but also the noise in the data set. False True False True Correlation is meant to represent the linear relationships between two nominal input variables. False
