Musk

Musk

The Musk database describes molecules occurring in different conformations. Each molecule is either musk or non-musk and one of the conformations determines this property. Such a problem is known as a multiple-instance problem, and is modeled by two tables molecule and conformation, joined by a one-to-many association. Confirmation contains a molecule identifier plus 166 continuous features. Molecule just contains the identifier and the class. There are two versions of the dataset, MuskSmall, containing 92 molecules and 476 confirmations, and MuskLarge, containing 102 molecules and 6598 confirmations.
