Algorithm 2. Extra tree model.

Result: Prediction of delamination size

Input: Sensor features with ground truth ${\left(m_p,n_p\right)}_{p=1}^x$

1 clf = ExtraTreeRegressor (mp, np)

2 clf.fit (n_est = 100, c = 'squared_error', m_s_s = 2, m_s_l = 1, max_features = 'auto')

Output: Extra Tree Prediction model
