Sequential pattern mining methods have been found to be applicable in a large number of domains. Sequential data is omnipresent. Sequential pattern mining methods have been used to analyze this data and identify patterns. Such patterns have been used to implement efficient systems that can recommend based on previously observed patterns, help in making predictions, […]

A sequential pattern is a series of item-sets; item-sets in sequences are in specific order.Sequential pattern mining helps to extract the sequences which are most frequent in the sequence database, which in turn can be interpreted as domain knowledge for several purposes[6].

Sequential Pattern Mining: Definition P. Singer, F. Lemmerich: Analyzing Sequential User Behavior on the Web ^Given a set of sequences, where each sequence consists of a list of elements and each element consists of a set of items, and given a user-specified min_support threshold, sequential pattern mining is to find all of

Module 3 consists of two lessons: Lessons 5 and 6. In Lesson 5, we discuss mining sequential patterns. We will learn several popular and efficient sequential pattern mining methods, including an Apriori-based sequential pattern mining method, GSP; a vertical data format-based sequential pattern method, SPADE; and a pattern-growth-based sequential pattern mining method, PrefixSpan.

Predictive maintenance utilizing supervised sequence rule mining . Oct 19, 2017 - IBM. Statistically significant event patterns predict the timing for performing entity maintenance. Event patterns are determined based on a target variable having an undesired value for a given entity when the event pattern occurs. Event patterns are filtered ...

2. SEQUENCE MINING The problem of mining sequential patterns can be stated as follows: Let I=[i 1, i 2, ..., i m] be a set of m distinct attributes, also called items.Anitemset is a nonempty unordered collection of items (without loss of generality, we assume that items of an item set are sorted in increasing order). All items in an item set are

For this, we apply a sequential version of MBA, sometimes called "sequential itemset mining" or "sequential pattern mining", to introduce a time component to the analysis [1]. Sequential itemset mining has been applied across many industries, from determining a patient's sequence of medical prescriptions [2] to detecting misuse ...

ISM is a novel algorithm that mines the subsequences that are most interesting under a probablistic model of a sequence database. Our model is able to efficiently infer interesting subsequences directly from the database. This is an implementation of the sequence miner from our paper: A Subsequence Interleaving Model for Sequential Pattern Mining.

The sequential pattern mining (SPM) problem consists of computing the set of frequent sequences, {s | sups ≥ θ}. The set of maximal frequent sequences for the illustrative sequence database, D={(bc)a(abc)d, cad(acd), a(ac)c}, under a minimum support θ=3 is {a(ac), cc}.

Sequence discovery, or sequential pattern mining, is a data mining technique that discovers statistically relevant patterns in sequential data. This mining program evaluates certain criteria, such as occurrence frequency, duration, or values in a set of sequences to find interesting hidden patterns.
