Practical Deep Learning – An Introduction

Machine Learning is among the most important developments in the history of computing. Deep learning is one of the fastest growing areas of machine learning and a hot topic in both academia and industry. This workshop will cover the fundamentals of deep learning with a focus on hands-on exercises leveraging some of the most popular deep learning frameworks.


Experience on programming, basic knowledge of calculus, linear algebra, and probability theory. Attendees are expected to bring their own laptops for the hands-on practical work.
