Dense class

Simple fully-connected Layer

Execute regular logic of dense-connected layer over given input data inputs:

activation.function(weights*inputs+biases)

Example:

// without NeuralNetwork
final inputs = Matrix.column([-1, 1, 2]); // inputs len == 3
final dense = Dense(1, activation: Activation.elu());
dense.init(3);
final output = dense.act(inputs);
print(output); // output is matrix 1⨯1

// within NeuralNetwork
final nn = NeuralNetwork(10, [
  Dense(32, activation: Activation.swish()),
  Dense(1, activation: Activation.linear(), useBiases: false)
], loss: Loss.mse());
