The book "Machine Learning Algorithms" is useful to readers passionate about artificial neural networks and data mining algorithms. The artificial neural networks are powerful modeling instruments for classes of problems in various areas, such as: bio-informatics, medicine, in order to early identify and classify specific genes belonging to certain illnesses, system engineering, predictive financial analyses, image processing, etc. Data mining algorithms can offer intelligent solutions for prediction, approximation, and classification problems with big data and databases in general.
