In Chapter 2‚ we learned about the different attribute types and how to use basic statistical descriptions to study data characteristics. These can help identify erroneous values and outliers‚ which will be useful in the data cleaning and integration steps. Data processing techniques‚ when applied before mining‚ can substantially improve the overall quality of the patterns mined and/or the time required for the actual mining. In this

Plato’s views were that there were two worlds the physical and the spiritual.
