Temporal extrapolation of heart wall segmentation in cardiac magnetic resonance images via pixel tracking

1 code implementation30 Jul 2022 Arash Rabbani, Hao Gao, Dirk Husmeier

The pixel tracking process starts from the end-diastolic frame of the heart cycle using the available manually segmented images to predict the end-systolic segmentation mask.

The Fully Convolutional Transformer for Medical Image Segmentation

2 code implementations1 Jun 2022 Athanasios Tragakis, Chaitanya Kaul, Roderick Murray-Smith, Dirk Husmeier

To address this shortcoming, we propose The Fully Convolutional Transformer (FCT), which builds on the proven ability of Convolutional Neural Networks to learn effective image representations, and combines them with the ability of Transformers to effectively capture long-term dependencies in its inputs.

Fast Parameter Inference in a Biomechanical Model of the Left Ventricle using Statistical Emulation

1 code implementation13 May 2019 Vinny Davies, Umberto Noè, Alan Lazarus, Hao Gao, Benn Macdonald, Colin Berry, Xiaoyu Luo, Dirk Husmeier

Emulation methods avoid computationally expensive simulations from the LV model by replacing the biomechanical model, which is defined in terms of explicit partial differential equations, with a surrogate model inferred from simulations generated before the arrival of a patient, vastly improving computational efficiency at the clinic.

On a New Improvement-Based Acquisition Function for Bayesian Optimization

no code implementations21 Aug 2018 Umberto Noè, Dirk Husmeier

Bayesian optimization (BO) is a popular algorithm for solving challenging optimization tasks.

Bayesian Optimization

Targeting Bayes factors with direct-path non-equilibrium thermodynamic integration

no code implementations21 Mar 2017 Marco Grzegorczyk, Andrej Aderhold, Dirk Husmeier

The method is based on a modified annealing path between the posterior distributions of the two models compared, which systematically avoids the high variance prior regime.

Inter-time segment information sharing for non-homogeneous dynamic Bayesian networks

no code implementations NeurIPS 2010 Dirk Husmeier, Frank Dondelinger, Sophie Lebre

Conventional dynamic Bayesian networks (DBNs) are based on the homogeneous Markov assumption, which is too restrictive in many practical applications.

Non-stationary continuous dynamic Bayesian networks

no code implementations NeurIPS 2009 Marco Grzegorczyk, Dirk Husmeier

Dynamic Bayesian networks have been applied widely to reconstruct the structure of regulatory processes from time series data.
