  • Neural Networks Are Used For Forecasting

    1425 Words  | 6 Pages

    Abstract— Neural networks are used for forecasting. The purpose of any learning algorithm is to find a function such that it maps a set of inputs to its correct output. Some input and output patterns can be easily learned by this neural networks. However, in the learning phase single-layer neural networks cannot learn patterns that are not linearly separable. Back propagation is a common method of training the neural networks. We are trying to develope the back propagation (BP) neural network to form

  • Artificial Neural Networks ( Ann )

    CHAPTER 5 Artificial Neural Networks (ANN) 5.1 Machine Learning In machine learning, systems are trained to infer patterns from observational data. A particularly simple type of pattern, a mapping between input and output, can be learnt through a process called supervised learning. A supervised-learning system is given training data consisting of example inputs and the corresponding outputs, and comes up with a model to explain those data (a process called function approximation). It does this

  • Artificial Neural Networks ( Anns )

    Artificial neural networks (ANNs) are computational algorithms loosely based on the human biological nervous system which work to model statistical data. An ANN “consists of processing elements known as neurons that are interconnected to each other and work in unison to answer a particular problem [, and] can be used in places where detecting trends and extracting patterns are too complex to be detected by either humans or other computer techniques.” Although recent in their explosion in popularity

  • Artificial Neural Networks And Predictive Policing

    1403 Words  | 6 Pages

    would a person react if he/she is suspected to commit a crime? How would that person feel if the police just randomly show up and ask for the intention of whatever that makes him/her suspicious? This is what will happen, frequently, if artificial neural networks are used as a mean for predictive policing. First, just to clarify, predictive policing is seeking to prevent future harm and reduce crime rates by analyzing information and patrolling areas based on the result. The police are able to predict

  • Artificial Neural Network Advantages And Disadvantages

    851 Words  | 4 Pages

    ABSTRACT- An Artificial Neural Network (ANN) is an information processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information [1]. Artificial Neural Networks (ANN) also called neuro-computing, or parallel distributed processing (PDP), provide an alternative approach to be applied to problems where the algorithmic and symbolic approaches are not well suited. The objective of the neural network is to transform the inputs into meaningful outputs. There

  • Neural Networks in Investments Essay example

    2681 Words  | 11 Pages

    Neural Networks in Investments I. ABSTRACT Investment managers often find themselves overwhelmed with the large amount of data obtained from the financial markets. Most of the data available is numeric and noisy in nature, making the decision-making process harder. These decisions usually rely on the integration of statistical measures that attempt to compress much of the data and qualitative depictions such as graphs and bar charts with news events and other pertinent information. Investment

  • Literature Review On Biological Neural Network

    chapter, we discuss a brief introduction of neural network and biometrics . Traditionally, the term neural network had been used to refer to a network or circuit of biological neurons. Neural networks are inspired by our brains. The modern usage of the term often refers to artificial neural networks, which are composed of artificial neurons or nodes. Thus, the term has two distinct usages: 2.1 Biological Neural Network generally, a biological neural network is consists of a set or sets of chemically

  • Feed Forward Neural Network Structure

    Feed-forward neural network structure consist of three layers of nodes : input layer, hidden layer , and output layer . The input layer nodes denoted $x_i , i in mathbb{N}$ ,where each of one of them is connected to all nodes in the hidden layer $h_j , j in mathbb{N}$ via connection weight that. Also , each node in the hidden layer is connected to all nodes in the output layer $ y_k , k in mathbb{N}$ through different connection weights . } label{fig:ffn1} end{figure}
