PCA + SVM - This notebook implements the following machine learning techniques on the indian pines dataset.
- Dimensionality Rreduction: The principal component analysis(PCA) is used to reduce the dimensions of the dataset.
- Classifier: The support vector machine(SVM) classifier is used to classsify the pixels of the HSI with classification report and the confusion matrix, classification map of the classifier is visualized.
-
Kernel PCA + SVM - This notebook implements the following machine learning techniques on the indian pines dataset.
- Dimensionality Rreduction: The Kernel principal component analysis(PCA) with 'rbf kernel' is used to reduce the dimensionality of the dataset.
- Classifier: The support vector machine(SVM) classifier is used to classsify the pixels of the HSI with classification report and the confusion matrix, classification map of the classifier is visualized.
