- The vector, M (1 × n), must be organized with the interconnection weights between the nodes of the hidden layers (n) and the nodes of the output layers;
- The matrix, W (m × n), must be organized with the interconnection weights between the nodes of the input layers (m) and the nodes of the hidden layers (n);
- Calculate the vector R = MWT, where R = [r1, r2, …, rm];
- Finally, we calculate the relative importance (RIi), in percentage, of each node i of the input layer, as given by Equation (5).
