[Mllab] Machine learning lecture question

Dear members of ML lab, I would like to participate in the lecture, even though I don't wish to take the exams or hand in the assignments (the reason is because I am a Phd student in Bonn and I don't need to take any exams). But I would like to attend the course and have access to the assignments so that I can complete them alone and learn the material. Is this possible? Moreover, should I register to the course for this reason or just come to the lecture? Best regards, Dimitris Oikonomopoulos
