Introduction to Data Mining (Second Edition)
We want to predict the last field using the other fields. There is also a discussion of scalability issues and factors to consider when selecting a clus- tering algorithm. A similar viewpoint is also present in statist ics and t he experimental sciences, with t heir emphasis on t he careful design of ex- periments to collect the data relevant to a specific hypothesis. In the store example aggregating over months loses information about which day of the week has the highest sales.
If t he attribute is ordinal, then order must be maintained by the assignment. Boston S;m Fr.
