  1. Artificial neural networks ( ANNs ), usually simply called neural networks ( NNs ), are computing systems vaguely inspired by the biological neural networks that constitute animal brains . An ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a biological brain.

    How do I make a neural network?

    Then we begin the training process:

    • Take the inputs from a training set example, adjust them by the weights, and pass them through a special formula to calculate the neuron’s output.
    • Calculate the error, which is the difference between the neuron’s output and the desired output in the training set example.
    • Depending on the direction of the error, adjust the weights slightly.

    What is neural network in simple words?
    • The concept of artificial neural networks represents mathematical models that are based on the information processing of the brain.
    • Neural networks are made up of many small processing units, the neurons connected to each other and have the ability to learn.
    • Neural networks store the knowledge distributed in socalled connection weights.

    How to initialize a neural network?
    init_net = init (net) returns a neural network net with weight and bias values updated according to the network initialization function, specified by net.initFcn, and the parameter values, specified by net.initParam. For more information on this function, at the MATLAB command prompt, type help network/init.

    Artificial neural network. An artificial neural network is an interconnected group of nodes, inspired by a simplification of neurons in a brain. Here, each circular node represents an artificial neuron and an arrow represents a connection from the output of one artificial neuron to the input of another. Artificial neural networks ( ANNs ...

    Recurrent neural networks (RNN) propagate data forward, but also backwards, from later processing stages to earlier stages. RNN can be used as general sequence processors.
    This architecture was developed in the 1980s. Its network creates a directed connection between every pair of units. Each has a time-varying, real-valued (more than just zero or one) activation (output). Each connection has a modifiable real-valued weight. Some of the nodes are called lab…

    https://en.wikipedia.org/wiki/Convolutional_neural_network

    In deep learning, a convolutional neural network (CNN, or ConvNet) is a class of artificial neural network(ANN), most commonly applied to analyze visual imagery. They are also known as Shift Invariant or Space Invariant Artificial Neural Networks (SIANN), based on the shared-weight architecture of the convolution kernels or filters that slide along input features and provide transl…

    Recurrent neural networks were based on David Rumelhart's work in 1986. Hopfield networks – a special kind of RNN – were (re-)discovered by John Hopfield in 1982. In 1993, a neural history compressor system solved a "Very Deep Learning" task that required more than 1000 subsequent layersin an RNN unfolded in time.
