This work presents the first method for providing formal reach-avoid guarantees, which combine and generalize stability and safety guarantees, with a tolerable probability threshold p in [0,1] over the infinite time horizon. Our method leverages advances in machine learning literature and it represents formal certificates as neural networks. In particular, we learn a certificate in the form of a reach-avoid supermartingale (RASM), a novel notion that we introduce in this work. Our RASMs provide reachability and avoidance guarantees by imposing constraints on what can be viewed as a stochastic extension of level sets of Lyapunov functions for deterministic systems. Our approach solves several important problems -- it can be used to learn a control policy from scratch, to verify a reach-avoid specification for a fixed control policy, or to fine-tune a pre-trained policy if it does not satisfy the reach-avoid specification. We validate our approach on 3 stochastic non-linear reinforcement learning tasks."}],"_id":"14830","conference":{"location":"Washington, DC, United States","end_date":"2023-02-14","name":"AAAI: Conference on Artificial Intelligence","start_date":"2023-02-07"},"status":"public","keyword":["General Medicine"],"date_updated":"2024-01-22T14:08:29Z","type":"conference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"call_identifier":"H2020","grant_number":"101020093","name":"Vigilant Algorithmic Monitoring of Software","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"},{"name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","call_identifier":"H2020"}],"oa_version":"Preprint","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"doi":"10.1609/aaai.v37i10.26407","ec_funded":1,"acknowledgement":"This work was supported in part by the ERC-2020-AdG 101020093, ERC CoG 863818 (FoRM-SMArt) and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385.","issue":"10","publication":"Proceedings of the 37th AAAI Conference on Artificial Intelligence","external_id":{"arxiv":["2210.05308"]},"publisher":"Association for the Advancement of Artificial Intelligence","publication_status":"published","date_created":"2024-01-18T07:44:31Z","month":"06"}
