WebFeb 10, 2024 · Introduction. Supervised classification problems require a dataset with (a) a categorical dependent variable (the “target variable”) and (b) a set of independent variables (“features”) which may (or may not!) be useful in predicting the class. The modeling task is to learn a function mapping features and their values to a target class. Web3. Clustering Analysis. Clustering is almost similar to classification, but in this cluster are made depending on the similarities of data items. Different groups have dissimilar or unrelated objects. It is also called data segmentation as it partitions huge data sets into groups according to the similarities. Various clustering methods are used:
