Decomposition of Heterogeneous Classification Problems

In some classi cation problems the feature space is heterogeneous in that the best features on which to base the classi cation are di erent in di erent parts of the feature space. In some other problems the classes can be divided into subsets such that distinguishing one subset of classes from another and classifying examples within the subsets require very di erent decision rules, involving di...

[Classification of drug-related problems].

BACKGROUND Drug-related problems are prevalent and cause considerable patient morbidity and in some cases death, as well as increased health care expenditures. A classification system may contribute to identify such problems, and further to resolve and prevent them. MATERIAL AND METHODS A draft classification was circulated to a panel of physicians and pharmacists and comments were requested....

Geometrical Complexity of Classification Problems

Despite encouraging recent progresses in ensemble approaches, classification methods seem to have reached a plateau in development. Further advances depend on a better understanding of geometrical and topological characteristics of point sets in high-dimensional spaces, the preservation of such characteristics under feature transformations and sampling processes, and their interaction with geom...
