The goal of Machine Learning is to develop techniques that enable a machine to "learn" how to perform certain tasks from experience.
The important part here is the learning from experience. That is, we do not try to encode the knowledge ourselves, but the machine should learn it itself from training data. The tools for this are statistical learning and probabilistic inference techniques. Such techniques are used in many real-world applications. This lecture will teach the fundamental machine learning know-how that underlies such capabilities. In addition, we show current research developments and how they are applied to solve real-world tasks.
Example questions that could be addressed with the techniques from the lecture include
- Is this email important or spam?
- What is the likelihood that this credit card transaction is fraudulent?
- Does this image contain a face?
The class is accompanied by exercises that will allow you to collect hands-on experience with the algorithms introduced in the lecture.
There will be both pen&paper exercises and practical programming exercises (roughly 1 exercise sheet every 2 weeks). Please submit your solutions electronically through the RWTH Moodle system.
We ask you to work in teams of 2-3 students.
The first half of the lecture will follow the book by Bishop. For the second half, we will use the Deep Learning book by Goodfellow as a reference.
