Boosting sparsity-induced autoencoder: A novel sparse feature ensemble learning for image classification
As a kind of unsupervised learning model, the autoencoder is usually adopted to perform the pretraining to obtain the optimal initial value of parameter space, so as to avoid the local minimality that the nonconvex problem may fall into and gradient vanishment of the process of back propagation. How...
