The students that still need to take the IRDM exam, can use the following doodle poll to pick a time slot. The selection is first-come, first-served. Select only one slot, specify your name, and please try to remember the time and date you picked. You need to register also at the examination office. |

We allocated a couple of additional slots for oral exams in the week August 10-14 to handle students with exceptional cases of conflicts to the already posted standard slots. If you think that your case is exceptional, please contact Heike Neu via email stating your conflicts, by the end of this week (i.e., end of June 28). We will decide on an individual basis whether or not we assign a new time slot. |
24.06.2015 |
We drop assignment 2(b) and 3(b) in exercise sheet 5. |

Exam registration is enabled now. If you are already qualified or still have the chance to qualify for the exam, use this doodle form to pick a slot for your IRDM exam. Select only one slot and specify your name. First-come, first-served. Write down the time and date of your slot before you click on the save button. You need to register also at the examination office. This registration link is only for the IRDM lecture, there is a separate one for the DDM lecture on its website. Registration is possible until end of June 2015. |

To clarify confusions on when to place a mark for an assignment that consists of multiple parts: Please mark an assignment as "done" if and only if you have accomplished some solution for each of the parts. |
22.04.2015 |
Students who attended the Data Mining course in last winter and took the exam, can also take this course. |

The presentation date is incorrect in Sheet 1. The presentation of the first assignment sheet will take place on 05.05.2015. |

Regulations for qualification to the final exam are posted. Please read carefully. |
08.04.2015 | To participate in this lecture, specifically for the exercises, you need to register in the KIS tool to this lecture, see KIS link above. |
Regulations
Please read carefully.
Students need to successfully participate in the exercise sessions, according to the regulations below, in order to get admitted to the final exam.
- There will be 5 exercise sheets.
- Each sheet consists of 3 assignments, which makes 15 assignments in total.
- Each assignment is equivalent to one point.
- A student needs to reach a total of at least 10 points throughout the semester to qualify for the final exam.
- Solutions to exercise sheets do not have to be handed in.
- Instead, at the beginning of each exercise session, the teaching assistant (TA) asks each student to mark on a sheet the assignments that he or she solved and can present.
- Then, for each assignment, the TA selects students among the ones that placed a mark for this respective assignment, to present the solution.
- This selection is done solely on discretion of the TA and does not require any justification.
- If the presented solution is correct, at least to the largest extent, the student retains the full point.
- Else if the presented solution is wrong but it is apparent that the student has spent time in solving it, zero points are given on the assignment.
- Else it should be obvious that the mark has been placed in a dishonest attempt to obtain a point without proper engagement with the assignment, in which case the entire sheet is assessed with zero points.
- For student that were not called to present, and, hence, the above cases do not apply, each made mark will translate to one point.
- This assessment, i.e., in which of the three cases the performance of the students falls into, is, again, solely done on discretion of the TA.
- Next to these 15 obligatory assignments there might be additional optional assignments, for which the above regulations do not apply.
Nonetheless, we would be happy to still see a lively participation in presenting and discussion their solutions.
