WebQuick check for over-fitting is high test error (low test accuracy) and low train error. (high train accuracy). It can be caused by using flexible models with high degree of freedom when model try to capture noise in training data. To avoid over-fitting regularization can be beneficial.

This is the approach we used in the previous course, Train a Supervised Machine Learning Model. Use the test set to prove that your model performs well on unseen data. driving licence online application ahmedabad
