Reinforcement Learning Under Probabilistic Spatio-Temporal Constraints with Time Windows

no code implementations29 Jul 2023 Xiaoshan Lin, Abbasali Koochakzadeh, Yasin Yazicioglu, Derya Aksaray

We propose an automata-theoretic approach for reinforcement learning (RL) under complex spatio-temporal constraints with time windows.

Temporal Relaxation of Signal Temporal Logic Specifications for Resilient Control Synthesis

no code implementations17 Aug 2022 Ali Tevfik Buyukkocak, Derya Aksaray

To this end, we formulate an optimal control problem that extracts state and input sequences by minimally violating the temporal requirements while achieving the desired predicates.

Control Barrier Functions with Actuation Constraints under Signal Temporal Logic Specifications

no code implementations7 Apr 2022 Ali Tevfik Buyukkocak, Derya Aksaray, Yasin Yazıcıoğlu

We propose control barrier functions (CBFs) for a family of dynamical systems to satisfy a broad fragment of Signal Temporal Logic (STL) specifications, which may include subtasks with nested temporal operators or conflicting requirements (e. g., achieving multiple subtasks within the same time interval).

Control Synthesis using Signal Temporal Logic Specifications with Integral and Derivative Predicates

no code implementations26 Mar 2021 Ali Tevfik Buyukkocak, Derya Aksaray, Yasin Yazıcıoğlu

We discuss the benefits of using the new predicates and illustrate them in a case study showing the influence of the new predicates on the trajectories of an autonomous robot.

Probabilistically Guaranteed Satisfaction of Temporal Logic Constraints During Reinforcement Learning

no code implementations19 Feb 2021 Derya Aksaray, Yasin Yazicioglu, Ahmet Semi Asarkaya

We propose a novel constrained reinforcement learning method for finding optimal policies in Markov Decision Processes while satisfying temporal logic constraints with a desired probability throughout the learning process.
