Artificial Neural Networks ( Ann ) - 2161 Words

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 by choosing from a class of model specified by the system’s designer. [Nature. ANN 4] 5.1.1 Machine Learning Applied to the Air Engine The rapid growth of data sets means that machine learning can now use complex model classes and tackle highly non-trivial inference problems. Such problems are usually characterized by several factors: The data are multi-dimensional; the underlying pattern is complex (for instance, it might be nonlinear or changeable); and the designer has only weak prior knowledge about the problem in particular, a mechanistic understanding is lacking. [Nature, ANN 4] 5.2 Overview of ANN Artificial Neural Networks (ANN) are a branch of the field known as Artificial Intelligence (AI) which may also consists of Fuzzy logic (FL) and Genetic Algorithms (GA). ANN are based on the basic model of the human brain with capability of generalization and learning. The purpose of this simulation to the simple model of human neural cell is to acquire the intelligentShow MoreRelatedArtificial Neural Networks ( Anns )1749 Words   |  7 Pages Artificial neural networks (ANNs) are computational algorithms loosely based on the human biological nervous system which work to model statistical data. An ANN â€Å"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 popularityRead MoreArtificial Neural Networks : An Example Of Machine Learning920 Words   |  4 PagesIn 1958 Psychologist Frank Rosenblatt invented the first artificial neural network. He called it Perceptron and hoped it would model the human brain and process visual data and learn to recognize objects. Artificial Neural Networks (ANNs) are expected to grow within the next few years. An artificial neural network is composed of interconnected artificial neurons that mimic some properti es of biological neurons. ANNs work like simulated brains. They are given software and be set up in a way that mimicsRead MoreStock Market Prediction Using Artificial Neural Networks And Regression Analysis871 Words   |  4 Pages Stock Market Prediction Using Artificial Neural Networks and Regression Analysis Tyler T.
