MSJEP Classifier: “Modified Strong Jumping Emerging Patterns” for Fast Efficient Mining and for handling attributes whose values are associated with taxonomies

Abstract

Modified Strong Jumping Emerging Patterns (MSJEPs) are those itemsets whose support increases from zero in one data set to non-zero in the other dataset with support constraints greater than the minimum support threshold (ζ). The support constraint of MSJEP removes potentially less useful JEPs while retaining those with high discriminating power. Contrast Pattern (CP)-tree-based discovery algorithm used for SJEP mining is a main-memory-based method. When the data set is large, it is unrealistic to assume that the CP-tree can fit in the main memory. The main idea to handle this problem is to first partition the data set into a set of projected data sets and then for each projected data set, we construct and mine its corresponding CP-tree. Trees of the projected data sets are called Separated Contrast Pattern Tree “SCP-trees” and Patterns generated from it are Called MSJEPs” Modified Strong Jumping Emerging Patterns”. Our proposal also investigates the weakness of emerging patterns in handling attributes whose values are associated with taxonomies and proposes using an MSJEP classifier to achieve better accuracy, better speed, and also handling attributes in taxonomy.

Key Technologies of Real-Time Location Service in Satellite Navigation and Positioning Network Based on Internet of Things

“…As an aggregated complex system, the IoT mainly consists of three parts: the perception control layer, which uses RFID, two-dimensional codes, sensors and other objects to perceive and identify objects [15]; the network transport layer transmits data information from the perception and recognition layer to the application service layer through the core network; and the application service layer uses cloud computing, data mining, and other intelligent computing technologies to complete the intelligent control and management of objects and apply them to specific industry fields [16][17][18]. e information interaction between the three parts, the transmission of instructions, and the architecture of the entire IoT are shown in Figure 1: e significance and process of the development of the IoT show that the IoT is a highly integrated network composed of various technologies.…”

“…With respect to these seemingly unrelated items, there seem on the surface to be no relationships, but association rules can find subtle relationships among them. Association rules were proposed in 1993 and play an important role in data mining ( Hassan et al, 2019 ; Hong et al, 2019a ; Liao and Ho, 2021 ). Many algorithms have been proposed on this basis.…”
