Dear colleagues, we would like to announce the workshop Stochastic Processes with Reinforcement Berlin, 3–6 November 2026 Weierstrass Institute for Applied Analysis and Stochastics (WIAS). The workshop will bring together researchers working on reinforcement from a variety of perspectives, including urn models, preferential attachment, reinforced random walks, branching and growth models, and learning-inspired stochastic dynamics. We also aim to stimulate discussion around emerging connections with reinforcement learning and multi-armed bandits. The programme will include a minicourse by Pierre Tarrès, invited talks, and a discussion session on "Probability meets AI". Registration is open until 11 October 2026. Further information, including the programme, abstracts, and registration, is available at: https://www.wias-berlin.de/workshops/SPR26/ We would be grateful if you could circulate this announcement to anyone who may be interested. Best wishes, Elena Magnanini and Tejas Iyer______________________________________________________________________________ Dr. Elena Magnanini Scientific Associate Weierstrass Institute for Applied Analysis and Stochastics (WIAS) Anton-Wilhelm-Amo-Straße 39 10117 Berlin, Germany Phone +49 30 20372-376 https://www.wias-berlin.de/~magnanini/ Legal Notice Legal entity: Forschungsverbund Berlin e.
