Seminars/meetings

Spring 2017

 

Fall 2016

For fall 2016, there will be a group meeting every second Thursday at 11:00-12:00 in room A042 (Realfagbygget). The members of the group will give a very quick presentation of their most recent activities and they will present their work schedule for the very next future. The presentation will be done using few slides, possibly following this template: ml_meetings_template.

Additionally, there will be 2 reading sessions each week.

The first reading session is on Tuesday at 12:00-13:00 in room 4.003 (Teknologibygget) and it will be moderated alternatively by Karl Øyvind and Luigi. One week, Karl Øyvind will discuss papers concerning machine learning application on health care. The other week, Luigi will discuss papers on the topic of domain adaptation.

The second reading session is on Thursday at 10:00-11:00 in room A042 (Realfagbygget) and it will be moderated alternatively by Sigurd and Michael. One week, Sigurd will discuss papers concerning kernel methods. The other week, Michael will discuss papers on the topic of deep learning.
