Task-Oriented Active Perception and Planning in Environments with Partially Known Semantics

no code implementations ICML 2020 Mahsa Ghasemi, Erdem Bulgur, Ufuk Topcu

Furthermore, as new data arrive, the belief over the atomic propositions evolves and, subsequently, the planning strategy adapts accordingly.

Adaptive Online Experimental Design for Causal Discovery

no code implementations19 May 2024 Muhammad Qasim Elahi, Lai Wei, Murat Kocaoglu, Mahsa Ghasemi

We propose a track-and-stop causal discovery algorithm that adaptively selects interventions from the graph separating system via allocation matching and learns the causal graph based on sampling history.

Submodular Information Selection for Hypothesis Testing with Misclassification Penalties

no code implementations17 May 2024 Jayanth Bhargav, Mahsa Ghasemi, Shreyas Sundaram

Further, we propose an alternate metric for information set selection which is based on the total penalty of misclassification.

Formal Methods for Autonomous Systems

no code implementations2 Nov 2023 Tichakorn Wongpiromsarn, Mahsa Ghasemi, Murat Cubuktepe, Georgios Bakirtzis, Steven Carr, Mustafa O. Karabag, Cyrus Neary, Parham Gohari, Ufuk Topcu

Formal methods refer to rigorous, mathematical approaches to system development and have played a key role in establishing the correctness of safety-critical systems.

No-Regret Learning in Dynamic Stackelberg Games

no code implementations10 Feb 2022 Niklas Lauffer, Mahsa Ghasemi, Abolfazl Hashemi, Yagiz Savas, Ufuk Topcu

The regret of the proposed learning algorithm is independent of the size of the state space and polynomial in the rest of the parameters of the game.

Scheduling

Multiple Plans are Better than One: Diverse Stochastic Planning

no code implementations31 Dec 2020 Mahsa Ghasemi, Evan Scope Crafts, Bo Zhao, Ufuk Topcu

In planning problems, it is often challenging to fully model the desired specifications.

Online Active Perception for Partially Observable Markov Decision Processes with Limited Budget

no code implementations4 Oct 2019 Mahsa Ghasemi, Ufuk Topcu

In applications in which the agent does not have prior knowledge about the available information sources, it is crucial to synthesize active perception strategies at runtime.

Identifying Sparse Low-Dimensional Structures in Markov Chains: A Nonnegative Matrix Factorization Approach

no code implementations27 Sep 2019 Mahsa Ghasemi, Abolfazl Hashemi, Haris Vikalo, Ufuk Topcu

We formulate the task of representation learning as that of mapping the state space of the model to a low-dimensional state space, called the kernel space.

Representation Learning

Perception-Aware Point-Based Value Iteration for Partially Observable Markov Decision Processes

no code implementations ICLR 2019 Mahsa Ghasemi, Ufuk Topcu

However, in a variety of real-world scenarios the agent has an active role in its perception by selecting which observations to receive.

Decision Making

Counterexamples for Robotic Planning Explained in Structured Language

no code implementations23 Mar 2018 Lu Feng, Mahsa Ghasemi, Kai-Wei Chang, Ufuk Topcu

Automated techniques such as model checking have been used to verify models of robotic mission plans based on Markov decision processes (MDPs) and generate counterexamples that may help diagnose requirement violations.
