Bayesian Semi-structured Subspace Inference

no code implementations23 Jan 2024 Daniel Dold, David Rügamer, Beate Sick, Oliver Dürr

To this end, we extend subspace inference for joint posterior sampling from a full parameter space for structured effects and a subspace for unstructured effects.

Single-shot Bayesian approximation for neural networks

1 code implementation24 Aug 2023 Kai Brach, Beate Sick, Oliver Dürr

We demonstrate that our single-shot MC dropout approximation resembles the point estimate and the uncertainty estimate of the predictive distribution that is achieved with an MC approach, while being fast enough for real-time deployments of BNNs.

Bayesian Calibration of MEMS Accelerometers

1 code implementation9 Jun 2023 Oliver Dürr, Po-Yu Fan, Zong-Xian Yin

This study aims to investigate the utilization of Bayesian techniques for the calibration of micro-electro-mechanical systems (MEMS) accelerometers.

Short-Term Density Forecasting of Low-Voltage Load using Bernstein-Polynomial Normalizing Flows

2 code implementations29 Apr 2022 Marcel Arpogaus, Marcus Voss, Beate Sick, Mark Nigge-Uricher, Oliver Dürr

The transition to a fully renewable energy grid requires better forecasting of demand at the low-voltage level to increase efficiency and ensure reliable control.

Bernstein Flows for Flexible Posteriors in Variational Bayes

1 code implementation11 Feb 2022 Oliver Dürr, Stephan Hörling, Daniel Dold, Ivonne Kovylov, Beate Sick

Variational inference (VI) is a technique to approximate difficult to compute posteriors by optimization.

Transformation Models for Flexible Posteriors in Variational Bayes

1 code implementation1 Jun 2021 Sefan Hörtling, Daniel Dold, Oliver Dürr, Beate Sick

In Bayesian neural networks, variational inference is widely used to approximate difficult-to-compute posteriors by variational distributions.

Deep and interpretable regression models for ordinal outcomes

1 code implementation16 Oct 2020 Lucas Kook, Lisa Herzog, Torsten Hothorn, Oliver Dürr, Beate Sick

We present ordinal neural network transformation models (ONTRAMs), which unite DL with classical ordinal regression approaches.

Integrating uncertainty in deep neural networks for MRI based stroke analysis

2 code implementations13 Aug 2020 Lisa Herzog, Elvis Murina, Oliver Dürr, Susanne Wegener, Beate Sick

For patient-level diagnoses, different aggregation methods are proposed and evaluated, which combine the single image-level predictions.

Single Shot MC Dropout Approximation

1 code implementation7 Jul 2020 Kai Brach, Beate Sick, Oliver Dürr

We demonstrate that our single shot MC dropout approximation resembles the point estimate and the uncertainty estimate of the predictive distribution that is achieved with an MC approach, while being fast enough for real-time deployments of BDNNs.

Deep transformation models: Tackling complex regression problems with neural network based transformation models

2 code implementations1 Apr 2020 Beate Sick, Torsten Hothorn, Oliver Dürr

Deep learning is known for outstandingly accurate predictions on complex data but in regression tasks, it is predominantly used to just predict a single number.
