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.

Prerequisites:

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.
