A Feedforward Neural Network is defined as a type of artificial neural network that processes signals in a one-way direction without any loops, making it static in nature. AI generated definition based on: Matlab for Neuroscientists, 2009 ...
The feedforward neural network, as a primary example of neural network design, has a limited architecture. Signals go from an input layer to additional layers. Some examples of feedforward designs are even simpler. For example, a single-layer perceptron model has only one layer, with a feedfo...

These weights and biases are the learn parameters theta in the definition of the neural network. Finally, the transformed input is passed through the activation function g. Most of the time, g does not contain parameters to be learned by the network. As an example, let us take a look ...
However when investigating applications of the network we realised that there are scenarios (the autoencoder in particular) where entanglement between different neurons is needed to perform the task. We have therefore chosen the following definition: Reversible→ unitary: The classical CNOT is ...
A definition is proposedfor optimal nonlinear features, and a constructive method, which has an iterative implementation, is derived for finding them. The learning algorithm always converges to a global optimum and the resulting network uses two layers to compute the hidden units. The general form ...

On the one hand, a formal definition of grammar complexity (i.e. Chomsky’s hierarchy6) provides a theoretical framework to study grammar learning; on the other hand, previous studies in humans set a well-defined experimental framework to compare human behavior with the performance of different ...
For a network with more layers, analogously, the gradient in the nth layer is calculated by propagating the loss function gradient from (n+1)th layer. We can calculate the loss function gradient for the weights in the nth network layer using the following recursive definition. ∂L∂Wn=fn...
One of the most common problems to be addressed when using neural networks is the function approximation problem (see [13, 63, 74]). This is why a problem of this kind has been included in this study. The definition of a function approximation problem is as follows: Given a function g(...
