Spectral Convolution Feature-Based SPD Matrix Representation for Signal Detection Using a Deep Neural Network
Convolutional neural networks have powerful performances in many visual tasks because of their hierarchical structures and powerful feature extraction capabilities. SPD (symmetric positive definition) matrix is paid attention to in visual classification, because it has excellent ability to learn pro...
