    Perceptrons:Early Deep Learning Agorithms

    one of the earliest supervised training algorithms is that of the perceptron,a basic neural network building block.

    Simple Perceptron Drawbacks

    To solve the problem,we'll need to use a multiple layer perceptron,also known as feedforward neural network

    Feedforward Neural Networks for Deep Learning

    A neural network is really just a composition of perceptrons,connected in different ways and operating on different activation functions.

    Training Perceptrons

    The most common deep learning algorithm for the supervised training of the multilayer is known as backpropagation.

    Autoencoders

    An autoencoders is typically a feedforward neural network which aims to learn a compressed,distributed representation (encoding) of a dataset.

    Restricted Boltzmann Machines

    Deep Belief Networks

    As with autoencoders,we can also stack Bolzmann machines to create a class known as deep belief networks(DBNs)

    Convolutional Networks

    examples

    You can see an example of convolutional networks trained (with backpropagation) on the MNIST data set(grayscale images of handwritten letters)
    There's also a nice JavaScirpt visualization of a similar network here
