Which technique of Artificial Intelligence (AI) / Statistical is used to see how one piece of data is linked to another piece of data?

  • A.Correlation
  • B.Decision Tree
  • C.Genetic Algorithms
  • D.Fuzzy Tree

Answer: A

The technique is correlation.

Correlation measures how strongly two variables are related, that is, how one piece of data changes as another changes, giving a coefficient between -1 and +1. It is a basic statistical tool of data mining and AI.

A decision tree classifies data through a sequence of decisions, and genetic algorithms search for solutions by imitating natural selection. 'Fuzzy tree' is not a standard technique. None of these is specifically about measuring how one item of data is linked to another.
