Neural Network-Based Coronary Heart Disease Risk Prediction Using Feature Correlation Analysis

Pseudocode 1

Pseudo code of the feature correlation analysis.

Feature set:

Learn a NN with X.

Calculate feature sensitivities of all features using the equation (2).

For i = 1 up to n

{

% Amplify feature x_i.

Learn a NN with .

Calculate feature sensitivities of all features using the equation (2).

}

Analyze the saved feature sensitivities whether there are features with big sensitivity changes due to amplifying a feature.
