  • * Multilayer perceptron neural network models were developed and trained using Levenberg-Marquardt and Scaled Conjugate Gradient algorithms.
  • * Model parameters were precisely tuned to optimize diagnostic performance.

    • Main Results:

    • * Nine noninvasive predictors significantly associated with dengue patient risk were identified.
    • * The diagnostic system achieved 75% prediction accuracy using the Scaled Conjugate Gradient algorithm.
    • * The Levenberg-Marquardt algorithm achieved 70.7% prediction accuracy in dengue risk classification.

    Conclusions:

    • * A noninvasive diagnostic system utilizing 9 predictors can effectively classify dengue patient risk.
    • * Neural network models, particularly with the Scaled Conjugate Gradient algorithm, show promise for dengue risk assessment.
    • * This system offers a valuable tool to support physicians in managing dengue disease severity.
