ML in PL
I'm proud to be a member of the awesome ML in PL Association, a non-profit organization devoted to fostering the machine learning community in Poland and around the world.
From 2021 I'm a member of the management board of ML in PL Association and try to support other members of the association in the organization of great machine learning-related events, including taking care of the recruitment of new members of the association and leading the development of new websites for ML in PL Conference 2022, ML in PL Conference 2023 and MLSS^S 2023
Before, I co-organized ML in PL Conference 2019, ML in PL Virtual Event 2020, and ML in PL Conference 2021 serving as Call for Contributions (Talks and Posters) coordinator.
Reviewing scientific papers
I try to review at least a dozen of papers each year. So far I have served as a reviewer for:- Conferences:
- NeurIPS 2020, 2021 (Outstanding Reviewer Award - top 8%), 2022 (Top Reviewer Award - top 8%), and 2023
- ICML 2021, 2022, and 2023
- ICLR 2022, 2023, and 2024
- IJCAI 2020, and 2021, and also AISTATS 2021
-
Journals:
- IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI)
- Machine Learning Journal
- Transactions on Machine Learning Research (TMLR)
Teaching
The one that learns the most from the course is the teacher.As part of my PhD/being an assistant, I teached/teach a few courses at Poznan University of Technology (PUT) related to the topics of Machine Learning, Artificial Intelligence, Data Science and Big Data:Wojciech Jaśkowski (my Eng. thesis supervisor)
- Advanced Methods of Computational Intelligence 2021, 2022 and 2023 (lectures + exercises)
based on Richard S. Sutton and Andrew G. Barto, Reinforcement Learning: An Introduction and selected chapters from Stuart Russell and Peter Norvig, Artificial Intelligence A Modern Approach. - Methods of Artificial and Computational Intelligence 2021 (exercises)
based on selected chapters from Stuart Russell and Peter Norvig, Artificial Intelligence A Modern Approach. - Big Data Processing 2019/2020 and Processing of Massive Datasets 2018/2019 (exercises)
based on selected chapters from Jure Leskovec, Anand Rajaraman, Jeff Ullman, Mining of Massive Datasets. - Information Theory and Lossless Compression Methods 2018 (exercises)
based on the first chapters from David J.C. MacKay, Information Theory, Inference, and Learning Algorithms.
Note: The course was awarded as the best new course in 2018 at the Institute of Computer Science.
