GraphDCA -- a Framework for Node Distribution Comparison in Real and Synthetic Graphs

no code implementations8 Feb 2022 Ciwan Ceylan, Petra Poklukar, Hanna Hultin, Alexander Kravchenko, Anastasia Varava, Danica Kragic

We argue that when comparing two graphs, the distribution of node structural features is more informative than global graph statistics which are often used in practice, especially to evaluate graph generative models.

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.

GeomCA: Geometric Evaluation of Data Representations

1 code implementation26 May 2021 Petra Poklukar, Anastasia Varava, Danica Kragic

Evaluating the quality of learned representations without relying on a downstream task remains one of the challenges in representation learning.

Enabling Visual Action Planning for Object Manipulation through Latent Space Roadmap

1 code implementation3 Mar 2021 Martina Lippi, Petra Poklukar, Michael C. Welle, Anastasia Varava, Hang Yin, Alessandro Marino, Danica Kragic

We present a framework for visual action planning of complex manipulation tasks with high-dimensional state spaces, focusing on manipulation of deformable objects.
