Neural Processes Mixed-Effect Models for Deep Normative Modeling of Clinical Neuroimaging Data

1 code implementation12 Dec 2018 Seyed Mostafa Kia, Andre F. Marquand

Normative modeling has recently been introduced as a promising approach for modeling variation of neuroimaging measures across individuals in order to derive biomarkers of psychiatric disorders.

Scalable Multi-Task Gaussian Process Tensor Regression for Normative Modeling of Structured Variation in Neuroimaging Data

no code implementations31 Jul 2018 Seyed Mostafa Kia, Christian F. Beckmann, Andre F. Marquand

Most brain disorders are very heterogeneous in terms of their underlying biology and developing analysis methods to model such heterogeneity is a major challenge.

PROMISSING: Pruning Missing Values in Neural Networks

no code implementations3 Jun 2022 Seyed Mostafa Kia, Nastaran Mohammadian Rad, Daniel van Opstal, Bart van Schie, Andre F. Marquand, Josien Pluim, Wiepke Cahn, Hugo G. Schnack

In this method, there is no need to remove or impute the missing values; instead, the missing values are treated as a new source of information (representing what we do not know).
