Is MC Dropout Bayesian?

Loic Le Folgoc, Vasileios Baltatzis, Sujal Desai +7

MC Dropout is a mainstream "free lunch" method in medical imaging for approximate Bayesian computations (ABC). Its appeal is to solve out-of-the-box the daunting task of ABC and un…

The Impact of Domain Shift on Left and Right Ventricle Segmentation in Short Axis Cardiac MR Images

Devran Ugurlu, Esther Puyol-Anton, Bram Ruijsink +5

Domain shift refers to the difference in the data distribution of two datasets, normally between the training set and the test set for machine learning algorithms. Domain shift is…

Quality-aware Cine Cardiac MRI Reconstruction and Analysis from Undersampled k-space Data

Ines Machado, Esther Puyol-Anton, Kerstin Hammernik +8

Cine cardiac MRI is routinely acquired for the assessment of cardiac health, but the imaging process is slow and typically requires several breath-holds to acquire sufficient k-spa…

Bayesian analysis of the prevalence bias: learning and predicting from imbalanced data

Loic Le Folgoc, Vasileios Baltatzis, Amir Alansary +8

Datasets are rarely a realistic approximation of the target population. Say, prevalence is misrepresented, image quality is above clinical standards, etc. This mismatch is known as…
