Multilayer Perceptron Neural Network
The model's engine is a Multilayer Perceptron (MLP), a type of deep neural network ideal for identifying complex, non-linear patterns in data. The architecture features three hidden layers with 60 neurons each, providing sufficient capacity to learn the intricate relationships between urinary peptides and the presence of CHD. This sophisticated structure allows the model to achieve high accuracy without overfitting, as confirmed by robust validation techniques.
Non-Invasive Data & Balancing
The model's input is urinary peptidomic data—a rich source of biomarkers collected non-invasively. A key challenge was the initial dataset imbalance (82 CHD cases vs. 345 controls). To solve this, the researchers employed the Synthetic Minority Over-sampling Technique (SMOTE). SMOTE generates new, synthetic data points for the minority class, creating a balanced dataset of 345 cases and 345 controls. This crucial step prevents the model from developing a bias towards the majority class and ensures it can accurately identify positive CHD cases.
Intelligent Feature Selection
From an initial pool of over 5,600 peptides, a Genetic Algorithm (GA) was used for intelligent feature selection. GAs mimic the process of natural selection to "evolve" the best possible combination of features. This powerful technique identified the 50 most informative peptide biomarkers for predicting CHD. By focusing only on these critical signals, the model becomes more efficient, less prone to noise, and ultimately more accurate and generalizable for real-world application.
