pasta: Pattern Analysis for Spatial Omics Data

1 code implementation2 Dec 2024 Martin Emons, Samuel Gunz, Helena L. Crowell, Izaskun Mallona, Reinhard Furrer, Mark D. Robinson

Spatial omics assays allow for the molecular characterisation of cells in their spatial context.

A class of modular and flexible covariate-based covariance functions for nonstationary spatial modeling

2 code implementations22 Oct 2024 Federico Blasi, Reinhard Furrer

The assumptions of stationarity and isotropy often stated over spatial processes have not aged well during the last two decades, partly explained by the combination of computational developments and the increasing availability of high-resolution spatial data.

Iterative Methods for Full-Scale Gaussian Process Approximations for Large Spatial Data

1 code implementation23 May 2024 Tim Gyger, Reinhard Furrer, Fabio Sigrist

Gaussian processes are flexible probabilistic regression models which are widely used in statistics and machine learning.

BiasBed - Rigorous Texture Bias Evaluation

1 code implementation CVPR 2023 Nikolai Kalischek, Rodrigo Caye Daudt, Torben Peters, Reinhard Furrer, Jan D. Wegner, Konrad Schindler

With the release of BiasBed, we hope to foster a common understanding of consistent and meaningful comparisons, and consequently faster progress towards learning methods free of texture bias.

Joint Variable Selection of both Fixed and Random Effects for Gaussian Process-based Spatially Varying Coefficient Models

no code implementations6 Jan 2021 Jakob A. Dambon, Fabio Sigrist, Reinhard Furrer

It relies on a penalized maximum likelihood estimation (PMLE) and allows variable selection both with respect to fixed effects and Gaussian process random effects.

Variable Selection Methodology

Is a single unique Bayesian network enough to accurately represent your data?

no code implementations18 Feb 2019 Gilles Kratzer, Reinhard Furrer

Unfortunately, they essentially all rely on very crude decisions that result in too simplistic approaches for such complex systems.

Comparison between Suitable Priors for Additive Bayesian Networks

no code implementations18 Sep 2018 Gilles Kratzer, Reinhard Furrer, Marta Pittavino

The second prior belongs to the Student's t-distribution, specifically designed for logistic regressions and, finally, the strongly informative prior is again Gaussian with mean equal to true parameter value and a small variance.

Information-Theoretic Scoring Rules to Learn Additive Bayesian Network Applied to Epidemiology

no code implementations3 Aug 2018 Gilles Kratzer, Reinhard Furrer

Bayesian network modelling is a well adapted approach to study messy and highly correlated datasets which are very common in, e. g., systems epidemiology.
