20. Incremental clickstream pattern mining with search boundaries

Abstract

Recently, there has been a growing interest in sequential pattern mining in data mining, with a particular focus on clickstream pattern mining. These areas hold the potential for discovering valuable patterns. However, traditional mining algorithms in these domains often assume that databases are static, simplifying the mining process. In reality, databases are updated incrementally over time, partially rendering a portion of the previous results invalid. This necessitates rerunning algorithms on updated databases to obtain accurate frequent patterns. As database size increases, this approach can become time-consuming and affect performance. To tackle this issue, we propose PSB-CUP to mine frequent clickstream patterns in an incremental update manner. PSB-CUP employs the concept of search borders to reduce the search space and the information retained in memory. Furthermore, an IDList generation method called “partial imbalance join” was proposed to reconstruct possibly missing information during the incremental process. This join method, however, requires more extra information to be cached in exchange for speed. We then improve this technique by introducing “recursive imbalance join”, removing the need for extra cached data in the PSB-CUP + algorithm. The experimental results show that our proposed algorithms are efficient for incremental clickstream pattern mining.

21. Effect of Cu2+ Ions Substitution on Structure and Photocatalytic Activity of CuxNi1−xFe2O4 Nanoparticles.

Abstract

Photocatalytic degradation is a promising emerging method for eliminating dye from contaminated water. The core of photocatalytic degradation lies in the design and preparation of high-performance catalysts that do not produce polluting secondary products. Here, we explore magnetic NiFe2O4 materials doped with varying amounts of Cu2+ ions (CuxNi1−xFe2O4, where x = 0–0.5) via the combustion method to target rhodamine B (RhB) dye removal. To validate whether Cu2+ is incorporated, the structural characteristics of the catalysts were analyzed using physical techniques. The photocatalytic activity of CuxNi1−xFe2O4 (x = 0–0.5) was evaluated based on the degradation of RhB, achieving 97.25% degradation efficiency under optimized conditions. The radical quenching results revealed that •OH played a pivotal factor in the photodegradation process. Additionally, chemical oxygen demand (COD) testing yielded a level of 24.67 mg L−1, significantly lower than the World Health Organization (WHO) drinking water standards. Overall, our findings reached high photocatalytic activity of Cu0.5Ni0.5Fe2O4 in removing a harmful dye (RhB) from water. [ABSTRACT FROM AUTHOR]

Abstract

Knowledge mining from single graph plays an important role in decision support systems on single graphs such as social networks, bioinformatics, etc. In recent years, the problem of Frequent Subgraph Mining (FSM) from a single graph have been developed and attracted several studies. However, the problem of mining association rules or links from frequent subgraphs has not had many contributions. In this article, we state the problem of direct mining association rules from frequent subgraphs. Existing approaches on this topic perform the task in two phases. First, they traverse the search space to directly discover parent-child relationships from the discovered frequent subgraphs, then association rules are generated. We propose a one-phase algorithm, named So-GPARs, to generate rules as soon as frequent supergraphs are constructed from already existing frequent subgraphs. Our experiments on three single graph datasets show that the one-phase algorithm is more efficient than the two-phase algorithm in terms runtime of the rules generating phase. [ABSTRACT FROM AUTHOR]
