Deep Learning of Part-Based Representation of Data Using Sparse Autoencoders With Nonnegativity Constraints.
IEEE Transactions on Neural Networks and Learning Systems, no. 12 (2016): 2486-2498
We demonstrate a new deep learning autoencoder network, trained by a nonnegativity constraint algorithm (nonnegativity-constrained autoencoder), that learns features that show part-based representation of data. The learning algorithm is based on constraining negative weights. The performance of the algorithm is assessed based on decomposi...More
