Apriori or Eclat algorithm for constructing association rules?

Question

data mining

Which algorithm is better and why? Eclat or Apriori?

Answer 1

In short, Eclat is DFS search and Apriori is BFS.
All top pattern mining algorithms are built on DFS (eg, prefixSpan, gSpan; no need to store front, effective cutoff), so Eclat is a good choice for unstructured data.
Or better yet, declarative miningZinc based on constraint programming:
