[HTML][HTML] Shared and unique brain network features predict cognitive, personality, and mental health scores in the ABCD study

J Chen, A Tam, V Kebets, C Orban, LQR Ooi… - Nature …, 2022 - nature.com
How individual differences in brain network organization track behavioral variability is a
fundamental question in systems neuroscience. Recent work suggests that resting-state and task…

Cross-ethnicity/race generalization failure of behavioral prediction from resting-state functional connectivity

J Li, D Bzdok, J Chen, A Tam, LQR Ooi, AJ Holmes… - Science …, 2022 - science.org
Algorithmic biases that favor majority populations pose a key challenge to the application of
machine learning for precision medicine. Here, we assessed such bias in prediction models …

[HTML][HTML] Comparison of individualized behavioral predictions across anatomical, diffusion and functional connectivity MRI

LQR Ooi, J Chen, S Zhang, R Kong, A Tam, J Li… - NeuroImage, 2022 - Elsevier
A fundamental goal across the neurosciences is the characterization of relationships linking
brain anatomy, functioning, and behavior. Although various MRI modalities have been …

[HTML][HTML] Proportional intracranial volume correction differentially biases behavioral predictions across neuroanatomical features, sexes, and development

E Dhamala, LQR Ooi, J Chen, R Kong, KM Anderson… - NeuroImage, 2022 - Elsevier
Individual differences in brain anatomy can be used to predict variations in cognitive ability.
Most studies to date have focused on broad population-level trends, but the extent to which …

[HTML][HTML] Comparison between gradients and parcellations for functional connectivity prediction of behavior

R Kong, YR Tan, N Wulan, LQR Ooi, SR Farahibozorg… - NeuroImage, 2023 - Elsevier
Resting-state functional connectivity (RSFC) is widely used to predict behavioral measures.
To predict behavioral measures, representing RSFC with parcellations and gradients are the …

[HTML][HTML] Relationship between prediction accuracy and feature importance reliability: An empirical and theoretical study

J Chen, LQR Ooi, TWK Tan, S Zhang, J Li, CL Asplund… - NeuroImage, 2023 - Elsevier
There is significant interest in using neuroimaging data to predict behavior. The predictive
models are often interpreted by the computation of feature importance, which quantifies the …

[HTML][HTML] Brain-based predictions of psychiatric illness–linked behaviors across the sexes

E Dhamala, LQR Ooi, J Chen, JA Ricard, E Berkeley… - Biological …, 2023 - Elsevier
Background Individual differences in functional brain connectivity can be used to predict
both the presence of psychiatric illness and variability in associated behaviors. However, …
