Alternating optimization method based on nonnegative matrix factorizations for deep neural networks
Tetsuya Sakurai, Akira Imakura, Yuto Inoue +1
The backpropagation algorithm for calculating gradients has been widely used in computation of weights for deep neural networks (DNNs). This method requires derivatives of objectiv…
