Fall 2022

Data Science Seminar: Graph Processing

Lecturers: Mourad Khayati, Alberto Lerner, and Rana Hussein 

Teaching language: English

Level: MSc students

Academic year: Fall 2022



Evaluation and Expectations


List of Papers


The seminar on data science involves presentations that cover recent topics on data science. The area of this year’s seminar is graph processing.  In the scope of this seminar, we investigate papers that describe algorithms and operators to process graphs. The papers explore mechanisms that highlight the strengths and weaknesses of these methods when applied to graphs.


The goal for the students is to learn how to critically read and study research papers, describe a paper in a report, and present it in a seminar. Under supervision, students will select one paper to study and compare it with related work. This seminar aims to help students gather in-depth knowledge of an advanced topic and develop the skills required to describe a complex problem from the time series field in the form of both a presentation, a written report, and an empirical evaluation.

IMPORTANT NOTE: The papers will be distributed on a first come first serve basis.

Evaluation and Expectations

The final grade depends on the quality of the report, presentation, reproducibility experiments, and active participation during the seminar. Each participant prepares a self-contained report of min 6 pages and gives a presentation of 30 minutes. The report should describe in detail the proposed technique(s). The report might contain a small running example, counterexample(s) if any, and should explore the extreme cases where the proposed approach would perform best and worst. The reproducibility consists of reproducing the same set of experiments introduced in the paper using a different setup (dataset, metric, parameters, etc.).

Advice on how to:

IMPORTANT NOTE: Attendance is mandatory for the two-class seminar sessions. The total number of participants will be limited to 10.
