The talk that I gave for the Berkeley MARL seminar can now be seen on youtube.
It gives an introduction to ideas of influence-based abstraction, focusing also on the inspirations from multiagent planning, as well as implications for future MARL.

DIALS accepted to NeurIPS’22
Our paper Distributed Influence-Augmented Local Simulators for Parallel MARL in Large Networked Systems was accepted to NeurIPS! It shows how influence-based abstraction can be used to parallelize and thus speed up multiagent reinforcement learning, while stabilizing the learning at the same time.
2 ILDM papers to appear at ICML

Senior Member AAAI
I was elected as a senior member of the association for the advancement of artificial intelligence (AAAI). The senior member status recognizes “AAAI members who have achieved significant accomplishments within the field of artificial intelligence”. I thank my nominators and the committee for this great honor.
First place ILDM team in RangL Pathways to Net Zero challenge
Aleksander Czechowski and Jinke He are one of the winning teams (‘Epsilon-greedy’) of The RangL Pathways to Net Zero challenge!
The challenge was to find the optimal pathway to a carbon neutral 2050. ‘RangL’ is a competition platform created at The Alan Turing Institute as a new model of collaboration between academia and industry. RangL offers an AI competition environment for practitioners to apply classical and machine learning techniques and expert knowledge to data-driven control problems.

AAMAS’22 paper: Bayesian RL to cooperate with humans
In our new paper Best-Response Bayesian Reinforcement Learning with BA-POMDPs for Centaurs, we investigate a machine whose actions can be overridden by the human. We show how Bayesian RL might lead to quick adaptation to unknown human preferences, as well as aiding the human to pursue its true goals in case of temporally inconsistent behaviors. All credits to Mert for all the hard work!
Wanted: 3 year Postdoc (Reinforcement learning)
I am looking for a postdoc. Please get in touch if interested!
Update for MMLL PhD applicants
Just a short update for the people who applied to our open positions in the MMLL. Due to a combination of holidays, new recruitment system, and a large number of applications, we are still screening. We hope to have more news soon!
Wanted: 2 PhD students in Reinforcement Learning
Within the Mercury Machine Learning Lab with booking.com and UvA, we are recruiting for 2 PhD students that want to tackle reinforcement learning for the real world!
Details here.
If you have a strong track record in ML and RL, and are interested, please do get in touch!
