Prediction modeling is often classified under the unsupervised machine learning methods.

True

False

$k-$means algorithm is a part of prediction data mining method.

True

False

The multi split methodology partitions data into exactly two mutually exclusive subsets called

training set and test set.

True

False

A data set is imbalanced when the distribution of different classes in the input variables are

significantly dissimilar.

True

False

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.

True

False

Correlation is meant to represent the linear relationships between two nominal input variables.

True

False

Data that is collected, stored, and analyzed in data mining is often private and personal. There is

no way to maintain individuals' privacy other than being very careful about physical data

security.

True

False
