Abstract

According to the characters of complex hyperspectral data, sparsity technique is introduced to deep convolutional neural network to handle feature extraction and classification problems. Combining sparse unsupervised learning method with neural network model, it is possible to get a good, sparse representation of the spectral information so that deep CNN model could extract feature information hierarchically and effectively. EPLS algorithm is applied in this paper to combine population sparsity and lifetime sparsity with the advantages of extracting deep feature information of CNN model to get a fine classification model. In the experiment, two hyperspectral data sets are applied for the proposed method, and the results demonstrate fine classification performances of the model.
