Discovering Frequent Episodes in Sequences
Sequences of events describing the behavior and actions of users or systems can be collected in several domains. In this paper we consider the problem of recognizing frequent episodes in such sequences of events. An episode is de ned to be a collection of events that occur within time intervals of a given size in a given partial order. Once such episodes are known, one can produce rules for des...

متن کاملDiscovering Chronic-Frequent Patterns in Transactional Databases
This paper investigates the partial periodic behavior of the frequent patterns in a transactional database, and introduces a new class of user-interest-based patterns known as chronic-frequent patterns. Informally, a frequent pattern is said to be chronic if it has sufficient number of cyclic repetitions in a database. The proposed patterns can provide useful information to the users in many re...
متن کاملDiscovering Diverse-Frequent Patterns in Transactional Databases
In the area of data mining, the process of frequent pattern extraction finds interesting information about the association among the items in a transactional database. The notion of support is employed to extract the frequent patterns. Normally, a frequent pattern may contain items which belong to different categories of a particular domain. The existing approaches do not consider the notion of...
متن کاملDiscovering Periodic-Frequent Patterns in Transactional Databases
Since mining frequent patterns from transactional databases involves an exponential mining space and generates a huge number of patterns, efficient discovery of user-interest-based frequent pattern set becomes the first priority for a mining algorithm. In many real-world scenarios it is often sufficient to mine a small interesting representative subset of frequent patterns. Temporal periodicity...
