Cím:Comparison of wrapper and filter feature selection algorithms on human activity recognition / Jozsef Suto, Stefan Oniga, Petrica Pop Sitar
Megjegyzések:Feature selection is an increasingly important part ofmachine learning. The purpose of feature selection is dimensionreduction in a large multi-dimensional data set and it can be thekey step of successful knowledge discovery in those problemswhere the number of features is large. This research area hashuge practical significance because it accelerates decisions andimproves performance. The requirements of specific applicationsin different kinds of research areas have led to the developmentof new feature selection techniques with different properties. Inthe last few decades, several feature selection algorithms havebeen proposed with their particular advantages anddisadvantages. Despite of the intensive research and the largeamount of works, the different kinds of feature selectionalgorithms have not been tested yet in the human activityrecognition problem. It was the main motivation of our work andthis paper tries to fill this gap. Therefore, in this article wepresent a conceptually simple naïve Bayesian wrapper featureselection method and compare it with some widely used filterfeature selection algorithms. The result of this workdemonstrates that, the wrapper technique outperforms filteralgorithms in this type of problem. In addition, this paper showsan example, when the classifier dependency of a wrapper methoddo not visible
