26 | |4. Relevant Information Paragraph: |
---|
27 | | There are 19 classes, only the first 15 of which have been used in prior |
---|
28 | | work. The folklore seems to be that the last four classes are |
---|
29 | | unjustified by the data since they have so few examples. |
---|
30 | | There are 35 categorical attributes, some nominal and some ordered. The |
---|
31 | | value ``dna'' means does not apply. The values for attributes are |
---|
32 | | encoded numerically, with the first value encoded as ``0,'' the second as |
---|
33 | | ``1,'' and so forth. An unknown values is encoded as ``-1.'' |
