Data characteristics that determine classifier performance
نویسندگان
چکیده
We study the relationship between the distribution of data, on the one hand, and classifier performance, on the other, for non-parametric classifiers. It is shown that predictable factors such as the available amount of training data (relative to the dimensionality of the feature space), the spatial variability of the effective average distance between data samples, and the type and amount of noise in the data set influence such classifiers to a significant degree. The methods developed here can be used to gain a detailed understanding of classifier design and selection.

Comparison of Classifier Algorithms in the Identification of Polypharmacy and Factors Affecting it in the Elderly Patients
Introduction: Prescribing and consuming drugs more than necessary which is known as polypharmacy, is both waste of resources and harm to patients. Polypharmacy is especially important for elderly patients; therefore, the factors affecting it must be identified and analyzed properly. Method: In this retrospective study, first, several classifier algorithms, i.e., C4.5, SVM, KNN, MLP, and BN for ...
