    Mechanistic Models: Compartment Models in Individual and Population Analysis

    Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least squares (OLS)...

    This study introduces a machine-learning framework to identify reliable biomarkers from complex biomedical data. The approach ensures reproducible results, highlighting Interleukin-18 (IL-18) as a key biomarker for COVID-19 hospitalization and intensive care.

    Area of Science:

    • Biomedical data analysis
    • Machine learning in healthcare
    • Translational research

    Background:

    • Identifying robust biomarkers from high-dimensional data is challenging due to pipeline-dependent rankings.
    • Existing methods lack reproducibility across different feature-selection and classification algorithms.

    Purpose of the Study:

    • To develop a disease-agnostic machine-learning framework for reproducible biomarker discovery.
    • To systematically benchmark multiple computational pipelines for robust candidate prioritization.

    Main Methods:

    • Benchmarking 25 feature-selection and classifier pipelines using five-fold cross-validation.
    • Aggregating feature evidence via consensus scoring and Robust Rank Aggregation.
    • Characterizing biomarker directionality using Cohen's d.

    Published on: October 11, 2018

    Main Results:

    • Achieved cross-validated mean F1 scores above 0.99 for SARS-CoV-2 hospitalization and intensive care admission.
    • Generated tiered, direction-aware biomarker lists with balanced classification errors.
    • Identified Interleukin-18 (IL-18) as a top-tier biomarker in both clinical phases.

    Conclusions:

    • The proposed framework enables principled and reproducible biomarker prioritization for binary clinical classification.
    • The methodology is generalizable to various biomedical datasets and clinical problems.
    • Consistent identification of IL-18 underscores its potential as a critical immune response biomarker.
