Svms and the curse of dimensionality
Splet24. okt. 2024 · The Curse of Dimensionality can be solved by Feature Selection Techniques or by Dimensionality Reduction Techniques ( PCA and LDA ). These feature selection techniques select the subset of... SpletFor small training samples, because the amount of training data may be less than the number of features, classification algorithms such as SVMs suffer from the curse of dimensionality . Therefore, in order to prevent such a problem, it is crucial to reduce the dimensionality of the features.
