Neural networks are composed by combination of neurons. The common architectures use conventional artificial neurons with aggregating functions or linear synaptic operation. The neuron connections help the network to perform complex behaviors. Artificial neural networks are structured to learn and generalize the knowledge, so the network learns by continuous adjustment of the weights of the connections. Each neuron has its own memory and ability to process information [1].
 
Some projects in this field under my supervision are as follows:  
 
Industrial predictive maintenance using neural networks
 
Figure2 In this work, an artificial neural network has been implemented for the predictive maintenance of an industrial machine, where the input data that was used has been taken from a vibration test on an alternating current motor.

The data that we obtained from the vibrometer was the frequency and the average of the vibration, which were used as inputs to feed the artificial neural network for the training stage.

The output of this unit gave us a value with which we can categorize the severity level of the machine motor, according to the severity table provided by ISO norm.

To test the correct functioning of the system, different data recorded from different motors have been used.

Prediction of Electrocardiograms via wireless communication
 
SSE





 In the present project the implementation of an Artificial Neural Network has been developed for the prediction of heartbeats via wireless, through a Python programming environment, which was programmed on the Biomedical Sensor platform using its ECG input module and wireless output.

The objective of this project is to predict a certain prediction horizon, according to the learning rate, the number of backward samples that will be used in training and the epochs specified as the learning cycles.

The acquisition of the signal (input) came from electrodes, which were placed on the chest surface near the heart. The visualization of the signal was presented through a graphical interface, which was developed in Python. The generated interface was designed to use the desired function by means of two buttons so that the system executes the action (training or prediction) that has been selected.

Deep Learning for Industrial Applications
 
Raspberry


Camera		 The present project seeks to implement a prototype of sensory vision system with application to classify images from a database.
The implementation of this work can have a positive impact in different fields of application. Example: new industrial processes or methods; The adequate diagnosis in the field of medical imaging; facial recognition in the field of civil security.

Currently, artificial vision systems are a very important part in most of all industrial processes, through the use of computer vision has been able to monitor the production processes and their final products. With this tool the quality and quantity of finished products has been increased. However, artificial vision systems are not completely flexible to be applied in all types of industry, and present greater limitations when exposed to conditions where graphics and noise are outside their parameters. It is not the same to recognize a piece of white color with lots of light, and recognize that same piece where the medium lacks luminosity. The identification of certain characteristics involves some physical and psychological concepts of the human brain. This is where artificial intelligence tools that can supply this extra degree of complexity become necessary. The demands are so high and traditional vision systems are not precise enough to meet those needs. Artificial neural networks are inspired by the understanding in the biology of our brain for the learning process. Deep learning is a tool of artificial intelligence in which nested layers of neural networks are massively seen. Nowadays, the recognition of computer images trained through deep learning is better than that of humans, in some scenarios.
