Outlier Detection as Instance Selection Method for Feature Selection in Time Series Classification [article]

David Cemernek
2021 arXiv   pre-print
An important step in the preprocessing phase is feature selection, which aims at better performance of prediction models by reducing the amount of features of a data set.  ...  The aim of this work was to filter instances provided to feature selection methods for these rare instances, and thus positively influence the feature selection process.  ...  A possibly more intuitive comparison of traditional classification to TSC is based on the assumption that the former only uses static features, whereas TSC uses dynamic features, for which the change in  ...
