Identifying consistent statements about numerical data with dispersion-corrected subgroup discovery
2017
Data mining and knowledge discovery
Preserved Fulltext
Other Versions
Existing algorithms for subgroup discovery with numerical targets do not optimize the error or target variable dispersion of the groups they find. ...
This often leads to unreliable or inconsistent statements about the data, rendering practical applications, especially in scientific domains, futile. ...

First, we formulate the broad model class of subgroup lists, i.e., ordered sets of subgroups, for univariate and multivariate targets that can consist of nominal or numeric variables, including traditional ...
Furthermore, we empirically show on 54 datasets that SSD++ outperforms previous subgroup discovery methods in terms of quality, generalisation on unseen data, and subgroup list size. ...
