DESCRIPTION
Data Sets for Data Mining Analysis ABSTRACT Preparing a data set for analysis is generally the most time consuming task in a data mining project, requiring many complex SQL queries, joining tables, and aggregating columns. Existing SQL aggregations have limitations to prepare data sets because they return one column per aggregated group. In general, a significant manual effort is required to build data sets, where a horizontal layout is required. We propose simple, yet powerful, methods to generate SQL code to return aggregated columns in a horizontal tabular layout, returning a set of numbers instead of one number per row. This new class of functions is called horizontal aggregations. Horizontal aggregations build data sets with a horizontal denormalized layout (e.g., point-dimension, observationvariable, instance-feature), which is the standard layout required by most data mining algorithms.

Data Sets for Data Mining Analysis
ABSTRACT
Preparing a data set for analysis is generally the most time consuming task in a
data mining project, requiring many complex SQL queries, joining tables, and
aggregating columns. Existing SQL aggregations have limitations to prepare data sets
because they return one column per aggregated group. In general, a significant manual
effort is required to build data sets, where a horizontal layout is required. We propose
simple, yet powerful, methods to generate SQL code to return aggregated columns in a
horizontal tabular layout, returning a set of numbers instead of one number per row.
This new class of functions is called horizontal aggregations. Horizontal aggregations
build data sets with a horizontal denormalized layout (e.g., point-dimension,
observationvariable, instance-feature), which is the standard layout required by most
data mining algorithms. We propose three fundamental methods to evaluate horizontal
aggregations: CASE: Exploiting the programming CASE construct; SPJ: Based on
standard relational algebra operators (SPJ queries); PIVOT: Using the PIVOT operator,
which is offered by some DBMSs. Experiments with large tables compare the proposed
query evaluation methods. Our CASE method has similar speed to the PIVOT operator
and it is much faster than the SPJ method. In general, the CASE and PIVOT methods
exhibit linear scalability, whereas the SPJ method does not.

What is IEEE?
The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries.
The IEEE describes itself as "the world's largest technical professional society -- promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members."
Why IEEE based projects?
It grantees for standard
It assured latest solution for problems
It delivers new patented technologies at an ever-increasing pace
It access world-class technical information provided by the IEEE and cut down your
research time.
