The article presents the authors' entry in the 2007 Data Mining Contest, sponsored by the IEEE International Conference on Data Mining. The authors designed a seven-step algorithm that incorporates both the Minkowski distance and the nearest-unlike-neighbor (NUN) distance. After building an initial training set, they computed class centers for each location and assigned labels to all unlabeled data. After calculating the Minkowski distance between all the class centers and the input vector, the label for the latter is set to the nearest center. NUN methodology can then be used to adjust for inconsistencies.

In the title compound, C15H14Br2ClNO3S, all bond lengths and angles show normal values. The five-membered ring exhibits a twist conformation. The crystal packing is stabilized mainly by van der Waals forces. [ABSTRACT FROM AUTHOR]

In the title compound, C8H6F3NO, the trifluoro­methyl group displays rotational disorder. The crystal packing is stabilized by inter­molecular O—H⋯N hydrogen bonds and van der Waals forces. [ABSTRACT FROM AUTHOR]

The mol­ecule of the title compound, C5H4ClNO2, is essentially planar, with normal values for the bond lengths and angles. In the crystal structure, inter­molecular O—H⋯N hydrogen bonds link the mol­ecules into zigzag chains extending along the b axis. [ABSTRACT FROM AUTHOR]

The six-membered sugar ring of the title compound, C21H26O11, adopts a chair conformation. The crystal structure is stabilized by inter­molecular C—H⋯O hydrogen bonds and van der Waals forces. [ABSTRACT FROM AUTHOR]
