Data Mining - (two class|binary) classification problem (yes/no, false/true)

About

Binary classification is used to predict one of two possible outcomes.

A two class problem (binary problem) has possibly only two outcomes:

  • “yes or no”
  • “success” or “failure”

and is much more known as a Bernoulli trial (or binomial trial)
