Mining Time Series and Event Sequences

The Seminar is available in Tucan right here.

Jilles Vreeken will give a talk about "Mining Sequential Patterns" on Thursday, Dec. 1, 2016 from 13:30 - 14:30 in C110

When and where?

The seminar meetings will be on Tuesdays at 17:10h in Room S2 02/E202 (Piloty building). 
The kick-off meeting is on Tuesday, October 25.

Organisation

The topics for the talks will be assigned in the kick-off meeting. The language of the seminar is English.

It is not necessary to have prior knowledge in artificial intelligence, but prior knowledge in data mining and machine learning is helpful. Participation is limited to 20 students. In case we have more students, students with prior knowledge in data mining and knowledge discovery will be preferred. The selection will be made at kick-off meeting.

For further questions feel free to send an email to ml-sem@ke.tu-darmstadt.de. No prior registration is needed, however, please stlll send us an email so that we are able to estimate beforehand the number of participants, and have your E-mail address for possible announcements. Also make sure that you are registered in TUCaN.

Content

In the course of this seminar we will try to get an overview on the current state of research in a domain. This year's topic will be Time Series and Event Sequences, i.e. methods and approaches for handling problems where the data have a temporal order. We will concentrate on recent papers published in workshops, journals, and conferences. 

The students are expected to give a 30 minute talk on the material they are assigned, followed by 15 minutes of questions. Although each topic is typically associated with a single paper, the point of the talk is not to exactly reproduce the entire contents of the paper, but to communicate the key ideas of the methods that are introduced in the paper. Thus, the content of the talk should exceed the scope of the paper, and demonstrate that a thorough understanding of the material was achieved. See also our general advices on giving talks.

Talks

The talks are expected to be accompanied by slides. In case you do not own a laptop, please send us the slides in advance, so that we can prepare and test the slides. The talk and the slides should be in English.Schedule

There will be two talks in each meeting. As mentioned above, each topic is associated with one paper, but the talk should not exactly reproduce the content of the paper, but communicate the key ideas of the introduced method.

All papers should be available on the internet or in the ULB. Note that Springer link often only works on campus networks (sometimes not even via VPN). If you cannot find a paper, contact us.

Grading

The slides, the presentation and the question and answers section of the talk will influence the overall grade. Furthermore, it is expected that students actively participate in the discussions, and this will also be part of the final grade. 
 
There is no need for a written verdict of the material.
 
To achieve a grade in the 1.x range, the talk needs to exceed the contentual recitation of the given material and include own ideas, own experience or even demos. An exact recitation of the papers will lead to a grade in the 2.x range. A weak presentation and lack of engagement in the discussions may lead to a grade in the 3.x range, or worse.
Please read also very carefully our guidelines for giving a talk.
