Addressing the NCR System

K-trivials Are Ncr

Definition 1.3. Suppose Z ∈ 2ω. A test relative to Z, or Z-test, is a set W ⊆ ω × 2<ω which is recursively enumerable in Z. For X ∈ 2ω, X passes a test W if and only if there is an n such that X 6∈ [Wn]. Definition 1.4. Suppose that m represents the measure μ on 2ω and that W is an m-test. • W is correct for μ if and only if for all n, ∑ σ∈Wn μ([σ]) ≤ 2 −n. • W is Solovay-correct for μ if and o...

Mining Association Rules on a Ncr Teradata System

Data mining from relations is becoming increasingly important with the advent of parallel database systems. In this paper, we propose a new algorithm for mining association rules from relations. The new algorithm is an enhanced version of the SETM algorithm (Houtsma & Swami 1995), and it reduces the number of candidate itemsets considerably. We implemented and evaluated the new algorithm on a p...
