template<typename Architecture_t>
class TMVA::DNN::TDenseLayer< Architecture_t >

Generic layer class.

This generic layer class represents a dense layer of a neural network with a given width n and activation function f. The activation function of each layer is given by \(\mathbf{u} = \mathbf{W}\mathbf{x} + \boldsymbol{\theta}\).

In addition to the weight and bias matrices, each layer allocates memory for its activations and the corresponding input tensor before evaluation of the activation function as well as the gradients of the weights and biases.

The layer provides member functions for the forward propagation of activations through the given layer.
