Deep learning is a key technology behind driverless cars, enabling them to recognize a stop sign, or to distinguish a pedestrian from a lamppost. Here is an example of how neural networks can identify a dog's breed based on their features. Deep learning is the name we use for "stacked neural networks"; that is, networks composed of several layers. Deep learning algorithms are constructed with connected layers. Neural networks have become one of the major thrust areas recently in various pattern recognition, prediction, and analysis problems In many problems they have established the state of the art -Often exceeding previous benchmarks by large margins 4 5 Breakthroughs with neural networks 6 Side note: For what I can see in this proposed model I can end up with an endless "loop", because maybe the output from the model 1 is categorical and the model 2 . Dropout may be implemented on any or all hidden layers in the network as well as the visible or input layer. Alexey Grigorevich Ivakhnenko published the first general on working Deep Learning networks. Deep learning is.

Week 1 : Introduction to Deep Learning, Bayesian Learning, Decision Surfaces. This process is shown in Figure 1. This is in contrast to those methods where traditionally hand crafted features are used. Dropout is implemented per-layer in a neural network. We can use neural network to approximate any function so it can theoretically be used to solve any problem. So in this model we have two neural networks that are fed each one with only categorical or continuous variables, and then the outputs (from both models) are feed to the third model.
