Mining Fuzzy Temporal Gradual Emerging Patterns

چکیده
Gradual emerging patterns (GEPs) are gradual item sets that occur less frequently in one data set and more another. For instance, let ‘fan speed’ ‘temperature’ be attributes of two numerical sets. A “the higher the speed, lower temperature” (which correlates a set’s attributes) becomes GEP if it is frequent (in terms support as pattern mining) However, such do not indicate how time gap impacts emergence. Many correlations appear over time, for instance when phenomena after some meteorological situation due to latency. Previous works have taken this temporal aspect into account. In paper, we introduce (TGEPs) which (TGPs) whose frequency supports increase significantly between transformed TGP temperature, almost 3 minutes later” TGEP occurs than Furthermore, extend border manipulation case mining TGEPs. addition, propose efficient ant colony optimization technique exploits heuristic approach construct

Mining Emerging Gradual Patterns
Mining emerging patterns aims at contrasting data sets and identifying itemsets that characterise a data set by contrast to a reference data set, so as to capture and highlight their differences. This paper considers the case of emerging gradual patterns, to extract discriminant attribute co-variations. It discusses the specific features of these gradual patterns and proposes to transpose an ef...
متن کاملMining Closed Gradual Patterns
With the steady development of the computing tools, we attended last three decades a considerable increase of the quantity of data stored in databases. So, extracting knowledge from this data is of paramount importance. Data mining is becoming an inescapable tool to reach this goal. Association rule extraction is one of the important tasks in data mining. This powerful technique has a wide rang...
متن کاملMining Multi-Relational Gradual Patterns
Gradual patterns highlight covariations of attributes of the form “The more/less X, the more/less Y”. Their usefulness in several applications has recently stimulated the synthesis of several algorithms for their automated discovery from large datasets. However, existing techniques require all the interesting data to be in a single database relation or table. This paper extends the notion of gr...
متن کاملFuzzy Orderings for Fuzzy Gradual Patterns
In mining gradual patterns the idea is to express co-variations of attributes, taking the direction of change of attribute values into account. These patterns are such as {the more A, the more B}, {the more A, the more B, the less C} or { the higher the speed, the higher the danger }. These patterns are denoted as {A≥B≥ }, { A≥B≥C≤} or { speed≥danger≥} respectively. Such patterns hold if the va...
متن کاملM2LGP: Mining Multiple Level Gradual Patterns
Gradual patterns have been studied for many years as they contain precious information. They have been integrated in many expert systems and rule-based systems, for instance to reason on knowledge such as “the greater the number of turns, the greater the number of car crashes”. In many cases, this knowledge has been considered as a rule “the greater the number of turns → the greater the number ...
