Unlearning Spurious Correlations in Chest X-ray Classification

no code implementations2 Aug 2023 Misgina Tsighe Hagos, Kathleen M. Curran, Brian Mac Namee

We train a deep learning model using a Covid-19 chest X-ray dataset and we showcase how this dataset can lead to spurious correlations due to unintended confounding regions.

Interpretable Weighted Siamese Network to Predict the Time to Onset of Alzheimer's Disease from MRI Images

1 code implementation14 Apr 2023 Misgina Tsighe Hagos, Niamh Belton, Ronan P. Killeen, Kathleen M. Curran, Brian Mac Namee

To this end, we select progressive MCI patients from the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset and construct an ordinal dataset with a prediction target that indicates the time to progression to AD.

FewSOME: One-Class Few Shot Anomaly Detection with Siamese Networks

1 code implementation17 Jan 2023 Niamh Belton, Misgina Tsighe Hagos, Aonghus Lawlor, Kathleen M. Curran

Our experiments demonstrate that FewSOME performs at state-of-the-art level on benchmark datasets MNIST, CIFAR-10, F-MNIST and MVTec AD while training on only 30 normal samples, a minute fraction of the data that existing methods are trained on.
