1、citeseer 数据集(citeseer dataset数据摘要：This is a link dataset built with permission from the CiteSeer web database. Each row is a scientific paper. Each attribute represents an author. In a given row, there is a 1 (one for every author associated with that row (i.e. paper, and a 0 (zero for every author

2、not associated with that row. The data file is itself stored in a sparse format, so don't expect a giant CSV matrix. The output is 1 (one if author J. Lee was involved in the paper. We expect that there are several authors in the CiteSeer database with the name J. Lee. J. Lee was chosen as the o

3、utput because he or she appeared in more papers than any other person in the database, at the time of compilation. Note, J.

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.
