This study introduces a new framework for medical image classification using regularized tensor decomposition. It effectively reduces dimensionality while maintaining clinical interpretability for multi-modal data.

Area of Science:

  • Medical Imaging
  • Machine Learning
  • Data Science

Background:

  • Multi-modal medical imaging datasets are high-dimensional.
  • Existing methods may not fully leverage all modalities simultaneously.
  • Clinical interpretability is crucial for medical applications.

Purpose of the Study:

  • To develop a general discriminative dimensionality reduction framework for multi-modal image-based classification.
  • To enable simultaneous use of all modalities for feature extraction.
  • To ensure the resulting lower-dimensional representation is clinically interpretable.

Main Methods:

  • A novel framework based on regularized tensor decomposition is proposed.
  • Exploration of different tensor factorization variants and their data implications.

  • Inspired by multi-view dimensionality reduction, two tensor decomposition methods are presented.

    • Main Results:

    • The framework successfully reduces high-dimensional medical imaging data to a lower-dimensional, discriminative representation.
    • Validation on a multi-modal longitudinal brain imaging study.
    • Comparison with a Support Vector Machine (SVM) based classifier showed competitive performance.

    Conclusions:

    • The proposed regularized tensor decomposition framework offers a discriminative and clinically interpretable approach for multi-modal medical image classification.
    • This method effectively integrates information from multiple imaging modalities.
    • The approach holds promise for advancing medical image analysis and classification tasks.
