Mutagenesis
The dataset comprises of 230 molecules trialed for mutagenicity on Salmonella typhimurium. A subset of 188 molecules is learnable using linear regression. This subset was later termed the ”regression friendly” dataset. The remaining subset of 42 molecules is named the ”regression unfriendly” dataset. Note that authors use this dataset with a variable set of the background knowledge (count of features in ”molecule” table) and consequently, the reported accuracies do not have to be directly comparable.
