Teaching Activities

At the current time, I am running a YouTube channel Be Expert in Minutes”. It freely provides high-quality video tutorials on topics related to "Text Mining", "Graph Algorithms", "Machine Learning", and Deep Learning" etc. I prepare these tutorials on my free time (weekend).

         My YouTube channel “Be Expert in Minutes” is highly appreciated by the people from technical, research & academic backgrounds for the good quality technical contents. It has successfully attracted a good volume of social media traffic and continually growing. (According to the Google Analytics report, till date (starting from March-End 2016 to Jan 15th 2017), My YouTube video Channel "Be Expert in Minutes" has crossed the count of 23500+ views with more than 90000+ minutes of watching time from 94 countries.)
