Markov chains and mappings of distributions on compact spaces

David J. Aldous, Shi Feng

Consider a compact metric space $S$ and a pair $(j, k)$ with $k \geq 2$ and $1 \leq j \leq k$ . For any probability distribution $θ \in P (S)$ , define a Markov chain on $S$ by: from state…

Mining fMRI Dynamics with Parcellation Prior for Brain Disease Diagnosis

Xiaozhao Liu, Mianxin Liu, Lang Mei +4

To characterize atypical brain dynamics under diseases, prevalent studies investigate functional magnetic resonance imaging (fMRI). However, most of the existing analyses compress…

Self-supervised arbitrary scale super-resolution framework for anisotropic MRI

Haonan Zhang, Yuhan Zhang, Qing Wu +7

In this paper, we propose an efficient self-supervised arbitrary-scale super-resolution (SR) framework to reconstruct isotropic magnetic resonance (MR) images from anisotropic MRI…

Deep learning reveals the common spectrum underlying multiple brain disorders in youth and elders from brain functional networks

Mianxin Liu, Jingyang Zhang, Yao Wang +7

Brain disorders in the early and late life of humans potentially share pathological alterations in brain functions. However, the key evidence from neuroimaging data for pathologica…
