While working on the Naive Bayes, I came across the subset argument, and don’t understand what it does.
For example-
train_emails = fetch_20newsgroups(categories = ['comp.sys.ibm.pc.hardware','rec.sport.hockey'], subset = 'train')
What does the subset=‘train’ bit do? How will my code be affected if I do not use it?
Sorry about replying with just a link but the quickest route would be to check the docs- https://scikit-learn.org/stable/modules/generated/sklearn.datasets.fetch_20newsgroups.html
Relevant section:
subset ‘train’ or ‘test’, ‘all’, optional
Select the dataset to load: ‘train’ for the training set, ‘test’ for the test set, ‘all’ for both, with shuffled ordering.
