This paper presents an efficient algorithm for mining complete frequent itemsets from typical datasets. The algorithm is partially based on FP-growth algorithm, in which the tree is built using smaller candidate sets for large 2-itemsets generated by using an efficient direct hashing technique and extracts the possible frequent itemsets directly fr...
In cube computation, aggregation is performed on the tuples (or cells) that share the same set of dimension values. Thus, it is important to explore sorting, hashing, and grouping operations to access and group such data together to facilitate computation of such aggregates. To compute total ...
In traditional file systems and databases, we use indexes, hashing, and other tricks for data access. We still have those tools, but we have added new ones.Star schemas,snowflake schemas, and multidimensional storage methods are all ways to get to the data faster, but in the aggregate rathe...
The resulting Tanimoto similarity histograms are plotted in Extended Data Fig.2a, while histograms of the predicted probability of them being active towards DRD2 are plotted in Extended Data Fig.2b. The PCB-generated scaffolds tend to be dissimilar to their seeds, in contrast to the FPB-generated...

A Novel Approach for Enhancing Direct Hashing and Pruning for Association Rule MiningData Mining has been considered as a promising field in the intersection of databases, artificial intelligence and machine learning. Association rule mining has been one of the most popular data mining subjects, which...
The proposed method reduces the false detection rate by mining the rules of malicious and normal code APIs in the portable executable (PE) file, grouping patterns using the direct hashing and pruning (DHP) algorithm, and classifying malicious and normal files using the SVM. The study shows that...
It can be augmented or potentially replaced with additional biometric markers such as voiceprints, spectrum readings, DNA hashing, iris scans, and the like, which would add additional "weight" or "reputation" to the initial ID as the ID is used over time, as a backup for proving ownership....
perfect hashingtraversal patternsHashing schemes are a common technique to improve the performance in mining not only association rules but also sequential patterns or traversal patters. However, the collision problem in hash schemes may result in severe performance degradation. In this paper, we ...
