Detailed explanation-1: -Questions : Enrichment is. (a) A stage of the KDD process in which new data is added to the existing selection. (b) The process of finding a solution for a problem simply by enumerating all possible solutions according to some pre-defined order and then testing them.
Detailed explanation-2: -The Process Is More Important Than the Tool STATISTICA Data Miner divides the modeling screen into four general phases of data mining: (1) data acquisition; (2) data cleaning, preparation, and transformation; (3) data analysis, modeling, classification, and forecasting; and (4) reports.
Detailed explanation-3: -The KDD Process. The knowledge discovery process(illustrates in the given figure) is iterative and interactive, comprises of nine steps. The process is iterative at each stage, implying that moving back to the previous actions might be required.
