In the course of this seminar we will address challenges coming up in real-world when machine learning (ML) applications are developed. Often, there are only few questions regarding the actual ML code [1], but a number of other major challenges must be addressed, such as

  • Is the ML model simple enough w.r.t. model tuning, serving costs, etc.?
  • Where can we get large labeled datasets for training and testing?
  • How to train the ML model over dirty data?
  • What is the best configuration for the selected ML model?
  • etc.

In this seminar, we aim to answer these questions by applying new research methods and approaches which provide easy ML application development, such as [2 - 6]. Students will choose a use-case and develop an ML application using approaches like automatic test data generation, auto-ML, hyperparameter optimization, ML over dirty data, etc. Applications may address use-cases such as ecommerce [7], logistics, transport [8, 9], fraud detection [10, 11, 12], finance [13], healthcare [14], online advertising [15], etc. Further use-cases and suggestions are most welcome!

In teams of two students, the students will complete the following tasks (percentages for grading):

  • (10%) Active participation during all seminar events.
  • (20%) Intermediate presentation demonstrating insights regarding your research project.
  • (00%) Regular meetings with advisor.
  • (20%) Implementation of your ML application.
  • (20%) Final presentation demonstrating your ML application.
  • (30%) Code & documentation (on GitHub). The documentation should contain information on how to execute and evaluate your solution. Furthermore, it should also show strengths and weaknesses of the implementation.


When: Thursday, 11:00 AM - 12:30 PM
Where: Online
