Image Classification with A Deep Network Model based on Compressive Sensing

Using compressive sensing to build the first layers of a neural network, and more importantly thinking of iterations of different reconstruction solvers as equilvant to layers of neural network, we are getting there. 

To simplify the parameter of the deep learning network, a cascaded compressive sensing model "CSNet" is implemented for image classification. Firstly, we use cascaded compressive sensing network to learn feature from the data. Secondly, CSNet generates the feature by binary hashing and block-wise histograms. Finally, a linear SVM classifier is used to classify these features. The experiments on the MNIST dataset indicate that higher classification accuracy can be obtained by this algorithm.
