Right for the Right Latent Factors: Debiasing Generative Models via Disentanglement

no code implementations1 Feb 2022 Xiaoting Shao, Karl Stelzner, Kristian Kersting

A key assumption of most statistical machine learning methods is that they have access to independent samples from the distribution of data they encounter at test time.

Decomposing 3D Scenes into Objects via Unsupervised Volume Segmentation

1 code implementation2 Apr 2021 Karl Stelzner, Kristian Kersting, Adam R. Kosiorek

We present ObSuRF, a method which turns a single image of a scene into a 3D model represented as a set of Neural Radiance Fields (NeRFs), with each NeRF corresponding to a different object.

Einsum Networks: Fast and Scalable Learning of Tractable Probabilistic Circuits

1 code implementation ICML 2020 Robert Peharz, Steven Lang, Antonio Vergari, Karl Stelzner, Alejandro Molina, Martin Trapp, Guy Van Den Broeck, Kristian Kersting, Zoubin Ghahramani

Probabilistic circuits (PCs) are a promising avenue for probabilistic modeling, as they permit a wide range of exact and efficient inference routines.

Structured Object-Aware Physics Prediction for Video Modeling and Planning

1 code implementation ICLR 2020 Jannik Kossen, Karl Stelzner, Marcel Hussing, Claas Voelcker, Kristian Kersting

When humans observe a physical system, they can easily locate objects, understand their interactions, and anticipate future behavior, even in settings with complicated and previously unseen interactions.

Random Sum-Product Forests with Residual Links

no code implementations8 Aug 2019 Fabrizio Ventola, Karl Stelzner, Alejandro Molina, Kristian Kersting

Tractable yet expressive density estimators are a key building block of probabilistic machine learning.

Conditional Sum-Product Networks: Imposing Structure on Deep Probabilistic Architectures

no code implementations21 May 2019 Xiaoting Shao, Alejandro Molina, Antonio Vergari, Karl Stelzner, Robert Peharz, Thomas Liebig, Kristian Kersting

In contrast, deep probabilistic models such as sum-product networks (SPNs) capture joint distributions in a tractable fashion, but still lack the expressive power of intractable models based on deep neural networks.

SPFlow: An Easy and Extensible Library for Deep Probabilistic Learning using Sum-Product Networks

1 code implementation11 Jan 2019 Alejandro Molina, Antonio Vergari, Karl Stelzner, Robert Peharz, Pranav Subramani, Nicola Di Mauro, Pascal Poupart, Kristian Kersting

We introduce SPFlow, an open-source Python library providing a simple interface to inference, learning and manipulation routines for deep and tractable probabilistic models called Sum-Product Networks (SPNs).

Probabilistic Deep Learning using Random Sum-Product Networks

no code implementations5 Jun 2018 Robert Peharz, Antonio Vergari, Karl Stelzner, Alejandro Molina, Martin Trapp, Kristian Kersting, Zoubin Ghahramani

The need for consistent treatment of uncertainty has recently triggered increased interest in probabilistic deep learning methods.
