CARRNN: A Continuous Autoregressive Recurrent Neural Network for Deep Representation Learning from Sporadic Temporal Data

Mostafa Mehdipour Ghazi, Lauge Sørensen, Sébastien Ourselin +1

Learning temporal patterns from multivariate longitudinal data is challenging especially in cases when data is sporadic, as often seen in, e.g., healthcare applications where the d…

On the Initialization of Long Short-Term Memory Networks

Mostafa Mehdipour Ghazi, Mads Nielsen, Akshay Pai +4

Weight initialization is important for faster convergence and stability of deep neural networks training. In this paper, a robust initialization method is developed to address the…

Multi-Domain Adaptation in Brain MRI through Paired Consistency and Adversarial Learning

Mauricio Orbes-Arteaga, Thomas Varsavsky, Carole H. Sudre +9

Supervised learning algorithms trained on medical images will often fail to generalize across changes in acquisition parameters. Recent work in domain adaptation addresses this cha…

Knowledge distillation for semi-supervised domain adaptation

Mauricio Orbes-Arteaga, Jorge Cardoso, Lauge Sørensen +5

In the absence of sufficient data variation (e.g., scanner and protocol variability) in annotated data, deep neural networks (DNNs) tend to overfit during training. As a result, th…

Training recurrent neural networks robust to incomplete data: application to Alzheimer's disease progression modeling

Mostafa Mehdipour Ghazi, Mads Nielsen, Akshay Pai +4

Disease progression modeling (DPM) using longitudinal data is a challenging machine learning task. Existing DPM algorithms neglect temporal dependencies among measurements, make pa…
