These lines of code are used to extract a sequence of values from the `sequence_target_drop_test` array with an index of `id_seq`. The `np.copy` function is used to make a copy of the sequence so that the original array is not modified. The value `mask_value` is replaced with `np.nan` to indicate missing values. Then, the `scaler_target` object is used to invert the scaling performed on the sequence during preprocessing. The resulting sequence is a set of actual values that can be compared to predicted values to evaluate the performance of a model.
