Dimensional Neuroimaging Endophenotypes: Neurobiological Representations of Disease Heterogeneity Through Machine Learning

no code implementations17 Jan 2024 Junhao Wen, Mathilde Antoniades, Zhijian Yang, Gyujoon Hwang, Ioanna Skampardoni, Rongguang Wang, Christos Davatzikos

Machine learning has been increasingly used to obtain individualized neuroimaging signatures for disease diagnosis, prognosis, and response to treatment in neuropsychiatric and neurodegenerative disorders.

Surreal-GAN:Semi-Supervised Representation Learning via GAN for uncovering heterogeneous disease-related imaging patterns

1 code implementation ICLR 2022 Zhijian Yang, Junhao Wen, Christos Davatzikos

The model first learns a transformation function from normal control (CN) domain to the patient (PT) domain with latent variables controlling transformation directions.

Subtyping brain diseases from imaging data

no code implementations16 Feb 2022 Junhao Wen, Erdem Varol, Zhijian Yang, Gyujoon Hwang, Dominique Dwyer, Anahita Fathi Kazerooni, Paris Alexandros Lalousis, Christos Davatzikos

The imaging community has increasingly adopted machine learning (ML) methods to provide individualized imaging signatures related to disease diagnosis, prognosis, and response to treatment.

PoseKernelLifter: Metric Lifting of 3D Human Pose using Sound

no code implementations CVPR 2022 Zhijian Yang, Xiaoran Fan, Volkan Isler, Hyun Soo Park

Based on this insight, we introduce a time-invariant transfer function called pose kernel -- the impulse response of audio signals induced by the body pose.

Generative Learning With Euler Particle Transport

no code implementations11 Dec 2020 Yuan Gao, Jian Huang, Yuling Jiao, Jin Liu, Xiliang Lu, Zhijian Yang

The key task in training is the estimation of the density ratios or differences that determine the residual maps.

Smile-GANs: Semi-supervised clustering via GANs for dissecting brain disease heterogeneity from medical images

no code implementations27 Jun 2020 Zhijian Yang, Junhao Wen, Christos Davatzikos

The model was first trained using baseline MRIs from the ADNI2 database and then applied to longitudinal data from ADNI1 and BLSA.
