“A very important and truly outstanding Contribution … . I recommend it as a ‘must read’ reference for researchers, practitioners, and higher research degrees students who want to experience truly exciting deep dive into a full-fledged deep learning. … the most important advantage of the book is the fact that it leaves its reader with a heightened ability to think – in different ways – about developing, evaluating, and implementing deep learning-based techniques and technologies in real life environments.” (Edward Szczerbicki, Intelligent Decision Technologies, Vol. 15, 2021)
