Aleksander Czechowski
Welcome to my page! I am an avid mathematician and computer scientist, with industrial experience in R&D, and passion for solving real world problems. Recently, I finished a postdoc at TU Delft, in Frans Oliehoek's group, on dynamical and game-theoretic aspects of multi-agent learning. In the past I worked on variety of topics, ranging from theoretical research on differential equations (at Jagiellonian University, with Piotr Zgliczyński), to real time optimal traffic management and integration with automated vehicles (at Dynniq B.V.). If you would like to talk about any of these topics, do not hesitate to contact me, by sending me a Linkedin invite.
News (from 2022 onwards):
I finished the postdoc at TUD and I am looking for a new project!
Our work on safety sets in multi-agent learning (with Frans Oliehoek) accepted for AAMAS 2023 as an extended abstract, stay tuned for the paper.
Congrats to Victoria Catalán Pastor and the rest of the team, our work Overcoming Traffic Sensor Malfunctions with Deep Learning presented at BNAIC 2022!
First place in RangL Pathways to Net Zero challenge, with Jinke He (Epsilon-greedy team). Check out the video and stay tuned for the paper.
Influence-aware Memory Architectures for Deep Reinforcement Learning, with Miguel Suau and the Influence group, to appear in Neural Computing and Applications.
AAMAS 2022 best paper runner up award for Poincaré-Bendixson Limit Sets in Multi-Agent Learning, with Georgios Piliouras.
Multi Robot Surveillance and Planning in Limited Communication Environments -- my student's Vibhav Kedege MSc thesis, accepted at ICAART 2022. Congrats Vibhav! Work done in collaboration with a robotic subsidiary of Almende B.V.
Old stuff (selection):
Constraint propagation and reverse multi-agent learning, an invited contribution to COMARL AAAI 2021 workshop.
Decentralized MCTS via Learned Team Models, with Frans Oliehoek, accepted at IJCAI 2020.
I gave a talk by invitation at ICIAM 2019, rigorous numerics workshop, courtesy of Kaname Matsue. Nice to keep in touch with the mathematics community!
Horizon 2020 MAVEN project on communication and coordination of intelligent infrastructure and vehicles (together with Dynniq, DLR, Hyundai, TomTom, Czech Technical University, and others) concluded! Glad to have been part of this project, pushing our transportation into the future. Check out our paper Cooperative queue data for adaptive traffic control at the ITS World Congress, Copenhagen, 2018.
I have led a team of engineers from Dynniq in successful implementation and validation of security protocols for V2I communication, at PKI Security Testfest, Reims 2018.
I mentored the Hack the Road hackathon at the circuit of Zandvoort, a fantastic event with many talented young people.
Papers from PhD at Jagiellonian University, with Piotr Zgliczyński on computer assisted proofs have been published: Existence of periodic solutions of the FitzHugh-Nagumo equations for an explicit range of the small parameter in SIADS, Rigorous numerics for PDEs with indefinite tail: existence of a periodic solution of the Boussinesq equation with time-dependent forcing in Schedae Informaticae
Symplectomorphisms and discrete braid invariants, the paper based on my Master thesis under supervision of Robert van der Vorst was published in Journal of Fixed Point Theory and Applications.
