Nonlinear feature transformation and deep fusion for Alzheimer's Disease staging analysis

作者:

Highlights:

• A novel nonlinear metric learning method is proposed to improve patient classifications of AD/MCI vs. normal controls.

• Thin-plate splines are integrated with SVM classifiers to make data points more (linearly) separable.

• Cross-sectional and longitudinal neuroimaging features estimated from MR brain images are fused through stacked denoising sparse auto-encoder.

• The effectiveness of the proposed feature transformation and fusion strategies is evaluated with ADNI dataset.
