The feedforward neural network is a specific type of early artificial neural network known for its simplicity of design. The feedforward neural network has an input layer, hidden layers and an output layer. Information always travels in one direction – from the input layer to the output layer...
A feedforward neural network definesa mappingfrom an input x to an output y through a function f of x and theta. For example, we use neural networks to produce outputs such as the location of all cars in a camera image. The function f takes an input x, and uses a set of learned p...

6.2.1Feedforward neural network FeedforwardNN[1]is the basic type of NN classifier. In thefeedforward NN, the data is passed through various input nodes until it reaches the output. Here, the data is moved in a single direction from the first tier to the output node. However, this proce...
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 ...
In this paper we consider possible extensions of the classical multilayer artificial neural network model to the situation when the signals processed by the network are by definition compound and possibly structured. We discuss existing approaches to this problem in various contexts and provide our own...
After the relations between any two distinct alternatives have been exploited, all the alternatives could be arranged into some preference preorders as defined in Definition 1. Definition 1 [32] (preference preorder) Given a MCDM problem with n distinct alternatives \(M_1,\ldots ,M_n\) and...
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 ...
Definition 3.2 Let X be a Banach space, f be a locally Lipschitz continuous function at x, and let d be any vector in X. The generalized directional derivative of f at x in the direction d is fo(x;d)=lim supt↓0y→xf(y+td)−f(y)t,where y is a vector in X and t is a...
