What is an example of a nominal attribute?

For example, map color is a nominal attribute that may have, say, five states: red, yellow, green, pink , and blue . Let the number of states of a nominal attribute be M .

How many nominal attributes are needed to convert a data table?

Suppose we would like to convert a nominal attribute X with 4 values to a data table with only binary variables. How many new attributes are needed? A machine learning problem involves four attributes plus a class. The attributes have 3, 2, 2, and 2 possible values each. The class has 3 possible values.

What is the difference between nominal and ordinal attributes?

Discrete attributes are those that describe a category, called nominal attributes. Those attributes that describe a category that where there is a meaning in the order for the categories are called ordinal attributes. The process of converting a real-valued attribute into an ordinal attribute or bins is called discretization.

What are the characteristics of a nominal variable?

The most important are the scale of measurement used, whether the distribution of the variable is discrete or continuous, and whether it is a primary or derived variable. A nominal variable (also known as a categorical variable) has a number of categories to which an observation can be assigned.
