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.

cMinMax: A Fast Algorithm to Find the Corners of an N-dimensional Convex Polytope

1 code implementation28 Nov 2020 Dimitrios Chamzas, Constantinos Chamzas, Konstantinos Moustakas

The algorithm is suitable for the fast registration of markers in augmentedreality systems and in applications where a computationally efficient real time feature detector is necessary. The algorithm can also be extended to N-dimensional polyhedrons.

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.

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.
