DeepGraphDMD: Interpretable Spatio-Temporal Decomposition of Non-linear Functional Brain Network Dynamics

1 code implementation5 Jun 2023 Md Asadullah Turja, Martin Styner, Guorong Wu

In this work, we apply GraphDMD -- an extension of the DMD for network data -- to extract the dynamic network modes and their temporal characteristics from the fMRI time series in an interpretable manner.

Anomaly Detection via Gumbel Noise Score Matching

no code implementations6 Apr 2023 Ahsan Mahmood, Junier Oliva, Martin Styner

We propose Gumbel Noise Score Matching (GNSM), a novel unsupervised method to detect anomalies in categorical data.

Harmonization Benchmarking Tool for Neuroimaging Datasets

1 code implementation15 Nov 2022 Tom Osika, Ebrahim Ebrahim, Martin Styner, Marc Niethammer, Thomas Sawyer, Andinet Enquobahrie

A major data pre-processing step for large, multi-site studies is to handle site effects by harmonizing data, generating a dataset that enables more powerful analyses and more robust algorithms.


Optimal Transport Features for Morphometric Population Analysis

1 code implementation11 Aug 2022 Samuel Gerber, Marc Niethammer, Ebrahim Ebrahim, Joseph Piven, Stephen R. Dager, Martin Styner, Stephen Aylward, Andinet Enquobahrie

We demonstrate the proposed optimal transport feature extraction step in the context of a volumetric morphometric analysis of the OASIS-1 study for Alzheimer's disease.

Multi-view Attention for gestational age at birth prediction

1 code implementation8 Jul 2022 Mathieu Leclercq, Martin Styner, Juan Carlos Prieto

We present our method for gestational age at birth prediction for the SLCN (surface learning for clinical neuroimaging) challenge.


Non-Euclidean Analysis of Joint Variations in Multi-Object Shapes

no code implementations6 Sep 2021 Zhiyuan Liu, Jörn Schulz, Mohsen Taheri, Martin Styner, James Damon, Stephen Pizer, J. S. Marron

This paper considers joint analysis of multiple functionally related structures in classification tasks.

Multiscale Score Matching for Out-of-Distribution Detection

1 code implementation ICLR 2021 Ahsan Mahmood, Junier Oliva, Martin Styner

We present a new methodology for detecting out-of-distribution (OOD) images by utilizing norms of the score estimates at multiple noise scales.

Learning Common Harmonic Waves on Stiefel Manifold -- A New Mathematical Approach for Brain Network Analyses

no code implementations1 Jul 2020 Jiazhou Chen, Guoqiang Han, Hongmin Cai, Defu Yang, Paul J. Laurienti, Martin Styner, Guorong Wu, Alzheimer's Disease Neuroimaging Initiative ADNI

To that end, we propose a novel connectome harmonic analysis framework to provide enhanced mathematical insights by detecting frequency-based alterations relevant to brain disorders.

Accurate Automatic Segmentation of Amygdala Subnuclei and Modeling of Uncertainty via Bayesian Fully Convolutional Neural Network

no code implementations19 Feb 2019 Yilin Liu, Gengyan Zhao, Brendon M. Nacewicz, Nagesh Adluru, Gregory R. Kirk, Peter A Ferrazzano, Martin Styner, Andrew L. Alexander

However, most of the previous deep learning work does not investigate the specific difficulties that exist in segmenting extremely small but important brain regions such as the amygdala and its subregions.

Fast Predictive Multimodal Image Registration

no code implementations31 Mar 2017 Xiao Yang, Roland Kwitt, Martin Styner, Marc Niethammer

We introduce a deep encoder-decoder architecture for image deformation prediction from multimodal images.
