{"department":[{"_id":"ToHe"}],"abstract":[{"text":"Machine learning and formal methods have complimentary benefits and drawbacks. In this work, we address the controller-design problem with a combination of techniques from both fields. The use of black-box neural networks in deep reinforcement learning (deep RL) poses a challenge for such a combination. Instead of reasoning formally about the output of deep RL, which we call the wizard, we extract from it a decision-tree based model, which we refer to as the magic book. Using the extracted model as an intermediary, we are able to handle problems that are infeasible for either deep RL or formal methods by themselves. First, we suggest, for the first time, a synthesis procedure that is based on a magic book. We synthesize a stand-alone correct-by-design controller that enjoys the favorable performance of RL. Second, we incorporate a magic book in a bounded model checking (BMC) procedure. BMC allows us to find numerous traces of the plant under the control of the wizard, which a user can use to increase the trustworthiness of the wizard and direct further training.","lang":"eng"}],"oa":1,"oa_version":"Published Version","date_published":"2020-09-21T00:00:00Z","conference":{"end_date":"2020-09-24","start_date":"2020-09-21","location":"Online Conference","name":" FMCAD: Formal Methods in Computer-Aided Design"},"type":"conference","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"file":[{"success":1,"access_level":"open_access","file_id":"9109","file_name":"2020_FMCAD_Alamdari.pdf","relation":"main_file","content_type":"application/pdf","date_updated":"2021-02-09T09:39:02Z","file_size":990999,"date_created":"2021-02-09T09:39:02Z","checksum":"d616d549a0ade78606b16f8a9540820f","creator":"dernst"}],"publisher":"TU Wien Academic Press","page":"138-147","day":"21","project":[{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211","name":"The Wittgenstein Prize","call_identifier":"FWF"}],"publication_identifier":{"eissn":["2708-7824"],"isbn":["9783854480426"]},"file_date_updated":"2021-02-09T09:39:02Z","language":[{"iso":"eng"}],"date_created":"2021-01-24T23:01:10Z","title":"Formal methods with a touch of magic","article_processing_charge":"No","status":"public","acknowledgement":"This research was supported in part by the Austrian Science Fund (FWF) under grant Z211-N23 (Wittgenstein Award).","license":"https://creativecommons.org/licenses/by/4.0/","publication_status":"published","scopus_import":"1","ddc":["000"],"citation":{"ista":"Alamdari PA, Avni G, Henzinger TA, Lukina A. 2020.
