            <parameter key="text" value="This Example Process mostly focuses on the transform binominal parameter. &#10;All remaining parameters are mostly for selecting the attributes. &#10;The Select Attributes operator also has many similar parameters for selection of attributes.&#10;You can study the Example Process of the Select Attributes operator if &#10;you want an understanding of these parameters. The Retrieve operator is used to &#10;load the Golf data set. A breakpoint is inserted at this point so that you can &#10;have look at the data set before application of the Nominal to Binominal operator. &#10;You can see that the 'Outlook' attribute has three possible values &#10;i.e. 'sunny', 'rain' and 'overcast'. The 'Wind' attribute has two possible values &#10;i.e. 'true' and 'false'. All parameters of the Nominal to Binominal operator are &#10;used with default values. Run the process. First you will see the Golf data set. &#10;Press the run button again and you will see the final results. &#10;You can see that the 'Outlook' attribute is replaced by three binominal attributes, &#10;one for each possible value of the original 'Outlook' attribute. &#10;These attributes are ' Outlook = sunny', ' Outlook = rain', and ' Outlook = overcast'. &#10;Only the value of one of these attributes is true for a specific example, the value of &#10;the other attributes is false. Examples whose 'Outlook ' attribute had the value 'sunny'&#10;in the original ExampleSet, will have the attribute ' Outlook =sunny' value set to &#10;'true'in the new ExampleSet, the value of the 'Outlook =overcast' and 'Outlook =rain' &#10;attributes will be 'false'. The numeric attributes of the input ExampleSet remain &#10;unchanged. The 'Wind' attribute was not replaced by two binominal attributes, &#10;one for each possible value of the 'Wind' attribute because this attribute is already &#10;binominal. Still if you want to break it into two separate binominal attributes, &#10;this can be done by setting the transform binominal parameter to true.&#10;"/>
