Classification of Illness

8.3K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

    Area of Science:

    • Data Science
    • Machine Learning
    • Bioinformatics

    Background:

    • Feature selection is crucial for reducing data dimensionality and enhancing classifier performance.
    • Interpreting results from multiple feature selection models and classifiers can be challenging.

    Purpose of the Study:

    • Introduce Meta-Best, a novel data-driven methodology for feature selection.
    • To identify a single, optimal feature set for classification targets.
    • To determine the optimal size and rank features by importance.

    Main Methods:

    • Developed a data-driven methodology named Meta-Best.
    • Applied Meta-Best to six distinct classification targets within the REGARDS dataset.
    • Evaluated the impact on neural network classification accuracy using the ROC Area Under Curve (AUC) metric.

    Main Results:

    • Meta-Best successfully identified optimal feature sets and their importance rankings.
    • The methodology demonstrated an improvement in neural network classification rate by 0.056 (ROC AUC).
    • Achieved better performance compared to a control group without feature selection.

    Conclusions:

    • Meta-Best offers an effective approach to streamline feature selection.
    • The method enhances the accuracy of neural networks in classification tasks.
    • Provides a more interpretable and efficient alternative for analyzing large datasets.
