Documentation

A Multi-Layer Perceptron.

MLP(int n_layers, int n_inputs_, ...)

Create a MLP with n_layers layers and n_inputs_ inputs. The definitions of the layer come then: it's a string followed by an integer for the number of outputs of the layer. Valid strings are "linear", "tanh", "sigmoid", "softmax", "log-softmax", "exp" and "softplus".

Example: to create an MLP with one linear layer and one softmax layer, MLP(2, n_inputs, "linear", n_outputs, "softmax", n_outputs);

void setWeightDecay(real weight_decay)

Set the weight decay in all Linear layers

This class has no child classes.
