Description

While we usually discuss how we can identify even better performing methods for data analysis, quite common in reality many data science projects fail since seemingly little steps are overlooked. Further, some of these fallacies are fairly obvious - when clearly presented. If well hidden in large datasets, they easily remain unidentified and lead to incorrect conclusions, even though purely technically all steps of a data analysis may have been performed correctly.

Within this seminar, we aim to identify these mishaps and pitfalls and discuss strategies to overcome them, both with regard to concrete examples, but also on a more general perspective.

Learning objectives

  • You learn to identify common mishaps in data analysis
  • You learn strategies to circumvent these mishaps
  • You learn to identify open challenges in data analysis
  • You can present a scientific manuscript in this field and lead a discussion

Requirements

You should have some mathematical background (at least Mathe 1+2 of the ITSE bachelor or comparable) as well as have taken at least one class in statistics. Good knowledge of English is required to understand and discuss current literature.

Learning

  • Seminar for master students 
  • Language of instruction: English
  • Maximum number of participants: 7

Topics will be presented in the first session (April 25, 2022). For topic assignments, participants will have to write an e-mail by May 2nd, 2022 in which they can give preferences for up to three of the presented topics. Then, the topics will be assigned by us. In case of too many applicants, we will decide randomly. As first talks will be scheduled May 16th will be the last time point to de-register from the class.
The seminar will be conducted on site (with an hybrid option if needed). Please register in the moodle of the course (https://moodle.hpi.de/course/view.php?id=293) for further information.

Examination

In the seminar, each participant will give a presentation about a predefined topic within the research area and write a short report. The final grade consists of the following two parts:

  • Presentation and discussion (65%)
  • Written report (35%)

Dates

First session April 25, 2022.
