Tenfold bootstrap procedure for support vector machines
(Wydawnictwa AGH, 2020) Vrigazova, Borislava; Ivanov, Ivan
Cross validation is often used to split input data into training and test sets in support vector machines. The two most commonly used cross validation versions are the tenfold and leave-one-out cross validation. Another commonly used resampling method is the random test/train split. The advantage of these methods is that they avoid overﬁtting in a model and perform model selection. However, they can increase the computational time for ﬁtting support vector machines by increasing the size of the dataset. In this research, we propose an alternative for ﬁtting SVM, which we call the tenfold bootstrap for support vector machines. This resampling procedure can signiﬁcantly reduce execution time despite the large number of observations, while preserving a model’s accuracy. With this ﬁnding, we propose a solution to the problem of slow execution time when ﬁtting support vector machines on big datasets.
