Machine Learning

Artificial Intelligence and Machine Learning algorithms are involved in a vast variety of scientific and industrial projects, contributing to the solution of the emerging problems, from data modeling and analysis to face recognition and self-driving cars. Regardless the practical utilization of machine learning algorithms, their core problem is the construction and training of an Artificial Neural Network, which is inspired from biological neurons -of the human nervous tissue system- which the ANN attempt to simulate. Neural networks regard almost all cases where the relationship between independent and dependent variables is investigated, even if it is highly non-linear and complex, such as predictions, regression, data modeling, feature significance, simulation of functions, partial differential equations, etc. In recent years, researchers and professionals are thoroughly utilizing artificial neural networks, as they have been successfully applied in an unusually wide range of fields of science and technology. Their success stems from the underlying theory of the exact approach of any continuous function in compact fields.
