Lee is not among input attributes.FormatThe spardat format is only capable of representing binary datasets with real outputs. The dataset is designed for

7、 sparse data, and is inefficient for dense data. Though the output may be a real number, the spardat loader we use binarizes the output with a user-supplied threshold. This format iswhitespace-delimited. Each line starts with the real output value, followed by a (whitespace-delimited list of attribu

8、te which have value 1 (one for that dataset row. The attributes are listed according to their index, starting from 0 (zero. The dataset is assumed to have as many attributes as necessary toaccomodate the highest-numbered attribute that appears in any row. However, there is no requirement that lower-

9、numbered attributes appear anywhere. For compatibility with some software, such as SVMlight, the attribute indicesmaybe be followed with ":1". Lines beginning with "#" are ignored. Example file with 8 attributes, mixing the standard attribute index format with the ":1" version:# The first line uses the :1 format.1.000000 0:1 3:1 7:1# The rest of t
