                    Notes          6.  Pattern evaluation: This step is used to identify the truly interesting patterns representing
                                       knowledge based on some interestingness measures.
                                   7.  Knowledge presentation: In this step, visualization and knowledge representation
                                       techniques are used to present the mined knowledge to the user.
                                   Figure 11.1 shows data mining as a step in process of knowledge discovery.

                                   11.1.2 Types of Data Mining Tasks


                                   Two types of Data mining task are:
                                   1.  Prediction Methods: This type of method uses some variable to predict unknown or future
                                       values of other variables.
                                   2.  Description Methods: This type of method finds human-interpretable patterns that describe
                                       the data.

                                   11.1.3 Purpose of Data Mining

                                   Data mining enables people to discover information that they can act on to better understand,
                                   selectively market to and retain their best customers, or sharply cut consumer fraud.

                                     Caution  In this we use pattern recognition logic to identity trends within a sample data set.

                                   1.  ................................. is the practice of automatically searching large stores of data to discover
                                       patterns and trends that goes beyond simple analysis.
