We are unaware of any countries that have four-digit zip codes, such as the 6269 indicated here, so this must be an error, right? Probably not. Zip codes for the New England states begin with the numeral 0. Unless the zip code field is defined to be character (text) and not numeric, the software will most likely chop off the leading zero, which is apparently what happened here. The zip code may well be 06269, which refers to Storrs, Connecticut, home of the University of Connecticut. The next field, gender, contains a missing value for customer 1003.
C. Example of a more complex deployment: Implement a parallel data mining process in another department. d. For businesses, the customer often carries out the deployment based on your model. This book broadly follows CRISP-DM, with some modifications. For example, we prefer to clean the data (Chapter 2) before performing exploratory data analysis (Chapter 3). 9 Two of these fallacies parallel the warnings we have described above. • Fallacy 1. There are data mining tools that we can turn loose on our data repositories, and find answers to our problems.
Data mining often deals with data that has not been looked at for years, so that much of the data contains field values that have expired, are no longer relevant, or are simply missing. The overriding objective is to minimize garbage in, garbage out (GIGO), to minimize the Garbage that gets Into our model, so that we can minimize the amount of Garbage that our models give Out.
