  • Utilized feature selection to identify discriminative features for optimal regression.
  • Implemented Relevance Vector Machine (RVM) for regression modeling.
  • Adopted a bagging framework to create ensemble models for stability and outlier mitigation.

    • Main Results:

    • The proposed regression scheme was validated on simulated and real medical image data using cross-validation.
    • Experimental results showed superior estimation accuracy compared to Support Vector Regression (SVR).
    • The method demonstrated enhanced generalizing ability, crucial for real-world clinical data.

    Conclusions:

    • The developed methodology offers a powerful approach for pattern regression in medical imaging.
    • The ensemble RVM technique provides stable and accurate continuous variable estimation.
    • This method holds significant potential for advancing disease staging and clinical progression prediction from medical images.
