Hey @lintasheelkumar, Cross-validation is primarily used in applied machine learning to estimate the skill of a machine learning model on unseen data. That is, to use a limited sample in order to estimate how the model is expected to perform in general when used to make predictions on data not used during the training of the model.

I would really advise you to go through the following links to understand cross validation score in detail.
