Having access to years of experience in the fields of statistics, business intelligence, and Machine Learning that Dr Stelios has accumulated is, in its own right, priceless.
However, more than any of his knowledge and experience, I value his eagerness to share them with his students, his openness to be contacted them and help them comprehend any concepts that they may have problem grasping. On top of these, his tireless willingness to discuss all relevant academic matters endlessly makes it fairly obvious to those who get to know him about how passionate he is about AI, Machine Learning, Statistics and Data Analytics.
