Naive Bayes uses word clues and math chance to sort text quickly.
What it does
Naive Bayes uses word clues and math chance to sort text quickly.
Independent: Things that don't affect each other • Probability: Math chance
How it works
- Look at words that appeared in old examples.
- Give each word a chance score for each group.
- Combine the word scores and pick the most likely group.
Uses & Applications
- Gmail can use this idea to help move junk emails into Spam.
- A school filter can flag rude comments for a teacher to review.
- A help desk can send messages about “password” to the account team.
In short
It is a fast probability calculator for sorting text, especially spam emails.
