Data Mining Process: Models, Process Steps

Steps In The Data Mining Process. The data mining process is divided into two parts i.e. Data Preprocessing and Data Mining. Data Preprocessing involves data cleaning, data integration, data reduction, and data transformation. The data mining part performs data mining, pattern evaluation and knowledge representation of data.

What is the Data Mining Process? (with pictures)

The data mining process is a tool for uncovering statistically significant patterns in a large amount of data. It typically involves five main steps, which include preparation, data exploration, model building, deployment, and review. Each step in the process involves a different set of techniques, but most use some form of statistical analysis.
