Exact analytical PGSE signal for diffusion confined to a cylindrical surface using a spectral Laplacian formalism
Erick J Canales-RodrÃguez, Chantal M. W. Tax, Juan Manuel Górriz +3
Pulsed-gradient spin-echo (PGSE) MRI experiments probe molecular self-diffusion through spin phase accumulation under time-dependent magnetic field gradients. For diffusion confine…
DualFlexKAN: Dual-stage Kolmogorov-Arnold Networks with Independent Function Control
Andrés Ortiz, Nicolás J. Gallego-Molina, Carmen Jiménez-Mesa +2
Multi-Layer Perceptrons (MLPs) rely on pre-defined, fixed activation functions, imposing a static inductive bias that forces the network to approximate complex topologies solely th…
A Review of Latent Representation Models in Neuroimaging
C. Vázquez-GarcÃa, F. J. MartÃnez-Murcia, F. Segovia Román +1
Neuroimaging data, particularly from techniques like MRI or PET, offer rich but complex information about brain structure and activity. To manage this complexity, latent representa…
