We call big data the sum of the digital data produced by new technologies - for professional or personal use - in real time, continuously and which growth is exponential.

An artificial neuron network is an organized group of interconnected artificial neurons, which conduct sophisticated operations or find a solution for complex problems with the help of a type of learning based on a form of artificial intelligence (AI).

An artificial neuron represents a basic unit of treatment of an artificial neural network —inspired by the biological neural network. This neuron converts the information-carrying signals it receives into a signal that it sends to other units in the network or to the output.

Reinforcement learning allows the computer to learn what to do from repeated experiences where it must find the best solution. In other words, he learns by trial and error, receiving or not a digital reward after each action.
