First, each internal node of the decision tree is marked with an attribute Ai. Second, each edge is labeled with a predicate that can be applied to the attribute associated with the parent node of it. Finally,
At this stage, one may decide to do away with some data parameters or bring in a few new ones. Here, data quality issues can be addressed and scanned for possible patterns in the data. The data preparation phase covers tasks such as table, case, and attribute selection. It also includes...
and assign weights to each attribute by using the entropy weight method, and then partition the tuples into a subset of complete tuples and several subsets of incomplete tuples based on their integrity rate, which is formulated with the weights of attributes and the missing degree of tuples....
The values in a discrete attribute column cannot imply ordering, even if the values are numeric. Moreover, even if the values used for the discrete column are numeric, fractional values cannot be calculated. Telephone area codes are a good example of discrete data that is numeric. The Discrete...
OLAP (Online Analytical Processing) is a computing method that enables users to easily and selectively extract and query data in order to analyze it from different points of view.
(1)Contextual attributes. The contextual attributes are used to determine the context (or neighborhood) for that instance. For example, in spatial data sets, the longitude and latitude of a location are the contextual attributes. In time-series data, time is a contextual attribute that determines...
If you have saved the mining model content as a dimension, you can also use other Multidimensional Expressions (MDX) functions that are avaialble for querying an attribute hierarchy. SELECT FROM <model>.CASES IsInNode (DMX) ClientSettingsGeneralFlag Class ...
An interesting and lesser-known application of word clouds is that we can make them based not on the word frequency but on any other attribute assigned to each word. For example, we can create a dictionary of countries, assign to each country the value of its population, and display this ...
