Abstract:

MBSA(Map-based BitSet Associaition Rule) algorithm was presented which used TreeMap class and a compressed BitSet class in Java to store Boolean values. MBSA algorithm scanned the transaction database only once and further database scans were replaced by BitSet logical AND operation, which efficiently speeded up the computation. MBSA algorithm had been applied to mine the association rules of red, green and blue bands associated with crop yield from remote sensing image of crop. It is useful for improve crop production.

Key words: remote sensing image, data mining, association rule, BitSet, TreeMap
