Tasks in Data Mining for R Language

Anomaly Detection 
→ Identification of unusual patterns, outliers, which help us in understanding the variation in data.
 Example:-

Association Rule Mining
→ Also referred to as market basket analysis, this method is used for discovering interesting "association" patterns among the variables.
Example :- The beer-diaper syndrome

Clustering
→ Identifying groups/classes in data which are similar to each other.
     The similarity inside the "cluster" is high and between the "clusters" is low.

Classification
→ Classification is the process of identifying to which category does an observation belong.
Example:-

 
Regression
→ With the help of regression, we can identify the extent of relationship among variables.
      Understanding how the "dependent" variable varies with respect to the variation in "independent" variable.
