Manifold learning based unsupervised classification methods will be unable to obtain satisfactory results because of the lack of training samples. The employment of training samples' information makes manifold learning based classification become supervised, and thus brings the improvement on classification accuracy. In order to make full use of this information, we emphatically consider the hyperspectral...
A novel deep learning classification method for hyperspectral data based on convolutional neural network is proposed in this paper. Deep learning means bringing multiple layers instead of one to the structure. Through convolution layers and pooling layers, the features in different layers are extracted from original spectral feature images. The key of this method is to restructure spectral feature...
To address the multi-classification problems of hyperspectral dataset, a new method with weighted kernel function based on Chernoff distance is proposed. Chernoff distance utilizes the information between categories and strengthens the separability of original dataset. The adjustable parameter in Chernoff distance can fit the hyperspectral dataset well compared with other least upper bounds. Pairwise...
