Examples of SmallLayeredNeuralNetwork

org.apache.hama.ml.ann.SmallLayeredNeuralNetwork
SmallLayeredNeuralNetwork defines the general operations for derivative layered models, include Linear Regression, Logistic Regression, Multilayer Perceptron, Autoencoder, and Restricted Boltzmann Machine, etc. For SmallLayeredNeuralNetwork, the training can be conducted in parallel, but the parameters of the models are assumes to be stored in a single machine. In general, these models consist of neurons which are aligned in layers. Between layers, for any two adjacent layers, the neurons are connected to form a bipartite weighted graph.
