Tensor-Based Multi-Modality Feature Selection and Regression for Alzheimer's Disease Diagnosis
This addresses the challenge of accurate diagnosis for Alzheimer's disease and mild cognitive impairment, but it appears incremental as it builds on existing multi-modality approaches with a novel tensor-based technique.
They tackled Alzheimer's disease diagnosis by proposing a tensor-based method for multi-modality feature selection and regression, achieving superior performance against state-of-the-art methods in identifying disease-specific regions and modality-related differences.
The assessment of Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI) associated with brain changes remains a challenging task. Recent studies have demonstrated that combination of multi-modality imaging techniques can better reflect pathological characteristics and contribute to more accurate diagnosis of AD and MCI. In this paper, we propose a novel tensor-based multi-modality feature selection and regression method for diagnosis and biomarker identification of AD and MCI from normal controls. Specifically, we leverage the tensor structure to exploit high-level correlation information inherent in the multi-modality data, and investigate tensor-level sparsity in the multilinear regression model. We present the practical advantages of our method for the analysis of ADNI data using three imaging modalities (VBM- MRI, FDG-PET and AV45-PET) with clinical parameters of disease severity and cognitive scores. The experimental results demonstrate the superior performance of our proposed method against the state-of-the-art for the disease diagnosis and the identification of disease-specific regions and modality-related differences.
