News categories

I trained multinomial naive Bayes on the headlines of 2,225 BBC articles in five categories and classified one headline I typed about an iPhone as tech.

Original tutorial by Aman Kharwal: News Classification (opens in a new tab)

What it printed in 2022

Numbers read from the saved notebook outputs. Cell numbers count every cell in the notebook, Markdown included, starting at 1.
Output	Value	Cell #
Category for one typed headline	tech	12

Cell # counts every cell from the top of the notebook, Markdown included, starting at 1.

No accuracy was printed.

The data

The BBC News dataset from the tutorial author's data repository.

What I'd do differently

Score it, and compare headlines alone with the full article text.
Use a stratified split, since the categories are not equal in size.
