Robust Dual-Model Collaborative Random Vector Functional Link Network
A. Quadir, A. Rahaman, Mushir Akhtar +1
Random vector functional link (RVFL) networks are lightweight and fast neural models that offer efficient training and strong generalization through randomized hidden-layer weights…
Balanced Twins: Causal Inference on Time Series with Hidden Confounding
Maha Ouali, Badih Ghattas, Emmanuel Flachaire +2
Accurately estimating treatment effects in time series is essential for evaluating interventions in real-world applications, especially when treatment assignment is biased by unobs…
Clustering Approaches for Mixed-Type Data: A Comparative Study
Badih Ghattas, Alvaro Sanchez San-Benito
Clustering is widely used in unsupervised learning to find homogeneous groups of observations within a dataset. However, clustering mixed-type data remains a challenge, as few exis…
Enhanced Vascular Flow Simulations in Aortic Aneurysm via Physics-Informed Neural Networks and Deep Operator Networks
Oscar L. Cruz-González, Valérie Deplano, Badih Ghattas
Due to the limited accuracy of 4D Magnetic Resonance Imaging (MRI) in identifying hemodynamics in cardiovascular diseases, the challenges in obtaining patient-specific flow boundar…
