The Planner Optimization Problem: Formulations and Frameworks

no code implementations12 Mar 2023 Yiyuan Lee, Katie Lee, Panpan Cai, David Hsu, Lydia E. Kavraki

Identifying internal parameters for planning is crucial to maximizing the performance of a planner.

Comparing Reconstruction- and Contrastive-based Models for Visual Task Planning

no code implementations14 Sep 2021 Constantinos Chamzas, Martina Lippi, Michael C. Welle, Anastasia Varava, Lydia E. Kavraki, Danica Kragic

Most methods learn state representations by utilizing losses based on the reconstruction of the raw observations from a lower-dimensional latent space.

Learning Sampling Distributions Using Local 3D Workspace Decompositions for Motion Planning in High Dimensions

1 code implementation29 Oct 2020 Constantinos Chamzas, Zachary Kingston, Carlos Quintero-Peña, Anshumali Shrivastava, Lydia E. Kavraki

Earlier work has shown that reusing experience from prior motion planning problems can improve the efficiency of similar, future motion planning queries.

LTLf Synthesis on Probabilistic Systems

no code implementations23 Sep 2020 Andrew M. Wells, Morteza Lahijanian, Lydia E. Kavraki, Moshe Y. Vardi

Linear Temporal Logic over finite traces (LTLf) has been used to express such properties, but no tools exist to solve policy synthesis for MDP behaviors given finite-trace properties.

How Much Do Unstated Problem Constraints Limit Deep Robotic Reinforcement Learning?

no code implementations20 Sep 2019 W. Cannon Lewis II, Mark Moll, Lydia E. Kavraki

Deep Reinforcement Learning is a promising paradigm for robotic control which has been shown to be capable of learning policies for high-dimensional, continuous control of unmodeled systems.

Using Local Experiences for Global Motion Planning

no code implementations20 Mar 2019 Constantinos Chamzas, Anshumali Shrivastava, Lydia E. Kavraki

In this work, we decompose the workspace into local primitives, memorizing local experiences by these primitives in the form of local samplers, and store them in a database.

Bounded Policy Synthesis for POMDPs with Safe-Reachability Objectives

no code implementations29 Jan 2018 Yue Wang, Swarat Chaudhuri, Lydia E. Kavraki

In this work, we study POMDPs with safe-reachability objectives, which require that with a probability above some threshold, a goal state is eventually reached while keeping the probability of visiting unsafe states below some threshold.
