An improved algorithm called UPro-Eclat is proposed to mine frequent itemsets from uncertain databases. UPro-Eclat is based on the PFIM and Eclat algorithms but uses a vertical mining method that adds probabilistic information to transaction IDs, builds a search tree recursively from subsets, and mines frequent patterns through depth-first traversal rather than repeatedly scanning the database. This approach allows UPro-Eclat to swiftly find probabilistic frequent itemsets without computing their probability in each possible world.

It uses a vertical mining method which is extension-based, adds probabilistic information in Tid, builds recursively the subset of search tree, and mines probabilistic frequent pattern by depth-first traversa. The algorithm UPro-Eclat can swiftly find probabilistic frequent itemset rather than compute their probability in each possible world.
