PolyWorld: Polygonal Building Extraction with Graph Neural Networks in Satellite Images

1 code implementation CVPR 2022 Stefano Zorzi, Shabab Bazrafkan, Stefan Habenschuss, Friedrich Fraundorfer

While most state-of-the-art instance segmentation methods produce binary segmentation masks, geographic and cartographic applications typically require precise vector polygons of extracted objects instead of rasterized output.

A dynamic connectome supports the emergence of stable computational function of neural circuits through reward-based learning

no code implementations13 Apr 2017 David Kappel, Robert Legenstein, Stefan Habenschuss, Michael Hsieh, Wolfgang Maass

These data are inconsistent with common models for network plasticity, and raise the questions how neural circuits can maintain a stable computational function in spite of these continuously ongoing processes, and what functional uses these ongoing processes might have.

Synaptic Sampling: A Bayesian Approach to Neural Network Plasticity and Rewiring

no code implementations NeurIPS 2015 David Kappel, Stefan Habenschuss, Robert Legenstein, Wolfgang Maass

We reexamine in this article the conceptual and mathematical framework for understanding the organization of plasticity in spiking neural networks.

Network Plasticity as Bayesian Inference

1 code implementation20 Apr 2015 David Kappel, Stefan Habenschuss, Robert Legenstein, Wolfgang Maass

General results from statistical learning theory suggest to understand not only brain computations, but also brain plasticity as probabilistic inference.

A theoretical basis for efficient computations with noisy spiking neurons

no code implementations18 Dec 2014 Zeno Jonke, Stefan Habenschuss, Wolfgang Maass

Furthermore, one can demonstrate for the Traveling Salesman Problem a surprising computational advantage of networks of spiking neurons compared with traditional artificial neural networks and Gibbs sampling.

Homeostatic plasticity in Bayesian spiking networks as Expectation Maximization with posterior constraints

no code implementations NeurIPS 2012 Stefan Habenschuss, Johannes Bill, Bernhard Nessler

Recent spiking network models of Bayesian inference and unsupervised learning frequently assume either inputs to arrive in a special format or employ complex computations in neuronal activation functions and synaptic plasticity rules.
