• In Machine Learning, it is common to perform a full parameter test.
  • Points to note:
    • Even if the best parameters are selected through grid search, they may be over-optimized for the test cases.
    • Using those parameters may not correctly validate the test cases.
    • Information leakage may occur from the test cases.
      • It may be necessary to add an additional layer of test cases.
