What is test size in Scikit learn?

Question

Can anyone tell me what is test size in Scikit learn?

Answer 1

In Scikit Learn, the ‘train_test_split” function will have the parameter ‘test_size’. This represents what proportion of the dataset to be included in the test dataset. It should be between 0 and 1.

If None, the test_size will be set to the complement of the train size. If train_size is also None, the default value of test_size will be 0.25.
