Neural Networks

It seems that you're in Germany. We have a dedicated site for Germany. Neural Networks: Computational Models and Applications covers a wealth of important theoretical and practical issues in neural networks, including the learning algorithms of feed-forward neural networks, various dynamical properties of recurrent neural networks, winner-take-all networks and their applications in broad manifolds of computational intelligence: pattern recognition, uniform approximation, constrained optimization, NP-hard problems, and image segmentation. By presenting various computational models, this book is developed to provide readers with a quick but insightful understanding of the broad and rapidly growing areas in the neural networks domain. Besides laying down fundamentals on artificial neural networks, this book also studies biologically inspired neural networks. Some typical computational models are discussed, and subsequently applied to objection recognition, scene analysis and associative memory. The studies of bio-inspired models have important implications in computer vision and robotic navigation, as well as new efficient algorithms for image analysis.

A recurrent neural network RNN is a class of artificial neural networks where connections between nodes form a directed graph along a temporal sequence. This allows it to exhibit temporal dynamic behavior. Derived from feedforward neural networks , RNNs can use their internal state memory to process variable length sequences of inputs. Both classes of networks exhibit temporal dynamic behavior. Both finite impulse and infinite impulse recurrent networks can have additional stored states, and the storage can be under direct control by the neural network. The storage can also be replaced by another network or graph, if that incorporates time delays or has feedback loops. Such controlled states are referred to as gated state or gated memory, and are part of long short-term memory networks LSTMs and gated recurrent units.

Deep learning

Deep learning also known as deep structured learning is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Learning can be supervised , semi-supervised or unsupervised. Deep-learning architectures such as deep neural networks , deep belief networks , recurrent neural networks and convolutional neural networks have been applied to fields including computer vision , machine vision , speech recognition , natural language processing , audio recognition , social network filtering, machine translation , bioinformatics , drug design , medical image analysis , material inspection and board game programs, where they have produced results comparable to and in some cases surpassing human expert performance. Artificial neural networks ANNs were inspired by information processing and distributed communication nodes in biological systems. ANNs have various differences from biological brains. Specifically, neural networks tend to be static and symbolic, while the biological brain of most living organisms is dynamic plastic and analogue.

Metrics details. The input for the ML approach is high accuracy data gathered in challenging molecular dynamics MD simulations at the atomic scale for varying temperatures and loading conditions. The effective traction-separation relation is recorded during the MD simulations. The raw MD data then serves for the training of an artificial neural network ANN as a surrogate model of the constitutive behavior at the grain boundary. Despite the extremely fluctuating nature of the MD data and its inhomogeneous distribution in the traction-separation space, the ANN surrogate trained on the raw MD data shows a very good agreement in the average behavior without any data-smoothing or pre-processing. Further, it is shown that the trained traction-separation ANN captures important physical properties and is able to predict traction values for given separations not contained in the training data. For example, MD simulations show a transition in traction-separation behaviour from pure sliding mode under shear load to combined GB sliding and decohesion with intermediate hardening regime at mixed load directions.

Many current computational models that aim to simulate cortical and hippocampal modules of the brain depend on artificial neural networks. However, such classical or even deep neural networks are very slow, sometimes taking thousands of trials to obtain the final response with a considerable amount of error. The need for a large number of trials at learning and the inaccurate output responses are due to the complexity of the input cue and the biological processes being simulated. This article proposes a computational model for an intact and a lesioned cortico-hippocampal system using quantum-inspired neural networks.

 - Меган. Беккер подошел и громко постучал в дверцу. Тишина. Он тихонько толкнул дверь, и та отворилась. Беккер с трудом сдержал крик ужаса. Меган сидела на унитазе с закатившимися вверх глазами. В центре лба зияло пулевое отверстие, из которого сочилась кровь, заливая лицо.

Киллер щелкнул миниатюрным тумблером, и очки превратились в дисплей. Опустив руки, он незаметными быстрыми движениями соединял кончики пальцев. Перед его глазами появилось сообщение, которое он должен был отправить. ТЕМА СООБЩЕНИЯ: П. КЛУШАР - ЛИКВИДИРОВАН Он улыбнулся. Часть задания заключалась в немедленном уведомлении. Но сообщать имена жертв… с точки зрения человека в очках в металлической оправе, это было признаком особой элегантности стиля.

 Нужно приступать к отключению, - настаивал Джабба.  - Судя по ВР, у нас остается около сорока пяти минут. Отключение - сложный процесс. Это была правда. Банк данных АНБ был сконструирован таким образом, чтобы никогда не оставался без электропитания - в результате случайности или злого умысла. Многоуровневая защита силовых и телефонных кабелей была спрятана глубоко под землей в стальных контейнерах, а питание от главного комплекса АНБ было дополнено многочисленными линиями электропитания, независимыми от городской системы снабжения.

 Сьюзан, - в его голосе послышалась решимость, - я прошу тебя помочь мне найти ключ Хейла.

Пришла пора действовать. Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала.
