This work presents an efficient approach for deriving itemsets with high fuzzy utility values from quantitative data. Each item in a transaction has its own profit and quantity, and the total fuzzy utility of it is considered. We also design a useful strategy to prune unpromising fuzzy candidate itemsets, thus making the mining process efficient. Through a series of experimental evaluations, the results...
Different from the existing algorithms, this work presents an efficient projection-based algorithm to find fuzzy frequent itemsets in quantitative databases. In particular, the proposed algorithm adopts the two strategies, indexing and pruning, to effectively speed up the execution efficiency in mining. In the experimental evaluation, the results on a synthetic dataset show the proposed algorithm...
This paper proposes an efficient fuzzy mining approach, namely GDF, to speed up the execution efficiency of finding fuzzy frequent itemsets in a quantitative database. Unlike the existing approaches, the proposed GDF adopts the data-reduction strategy to effectively reduce the number of unpromising candidate fuzzy itemsets for mining. The experimental results on a synthetic dataset reveal that the...
Ankle sprain is one of the most common sport injuries during landing of counter movement jump and straddle jump in baseball and volleyball exercise. Ankle sprain patients will lead to ankle functional instability. Most of functional instability patients occurs recurrent ankle sprain. The purpose of this study are estimate the ankle joint kinetics and ground impact pattern during landing in counter...
