Abstract: Abstract: Discovering frequent itemsets is an essential task in association
rules mining and it is considered to be computationally
expensive. To find the frequent itemsets, the algorithm of frequent
pattern growth (FP-growth) is one of the best algorithms
for mining frequent patterns. However, many experimental
results have shown that building conditional FP-trees during
mining data using this FP-growth method will consume
most of CPU time. In addition, it requires a lot of space to save
the FP-trees. This paper presents a new approach for mining
frequent item sets from a transactional database without building
the conditional FP-trees. Thus, lots of computing time and
memory space can be saved. Experimental results indicate
that our method can reduce lots of running time and memory
usage based on the datasets obtained from the FIMI repository
website.
