A Practical Approach for Clustering Transaction Data
To these problems, we propose a parameter-free transactional clustering algorithm. Our algorithm first scans the data set in a sequential manner such that the destination of the next transaction is guided by a novel objective function. Once the first scan of the data set is completed, the algorithm performs a few other passes over the data set ...

Transactional Leadership | SpringerLink
Transactional leadership began as the opposing theory to the more exciting transformational leadership model. It was seen as the kind of mundane relationship that one experiences in working with their supervisor; e.g., "if one completes this task, one's employer may reward one with another task to complete, and if many of these tasks are …
Graph mining approach to suspicious transaction detection
Suspicious transaction detection is used to report banking transactions that may be connected with criminal activities. Obviously, perpetrators of criminal acts strive to make the transactions as innocent-looking as possible. Because activities such as money laundering may involve complex organizational schemes, machine learning techniques based on …
Association Rule Mining Explained With Examples
Sample Transaction Data. Using this dataset, let us try to understand different terminologies in association rule mining. Itemset. An itemset is a set containing one or more items in the transaction dataset. For instance, {Milk}, {Milk, Bread}, {Tea, Ketchup}, and {Milk, Tea, Coffee} are all itemsets. An itemset can also be an empty set.

Data Mining Multidimensional Association Rule
Multi dimensional affiliation rule comprises of more than one measurement. Example – buys (X, "IBM Laptop computer")buys (X, "HP Inkjet Printer") Three approaches in mining multi dimensional affiliation rules are as following. Discretization is static and happens preceding mining. Discretized ascribes are treated as unmitigated.
An efficient pattern growth approach for mining fault tolerant …
To mine frequent itemsets in the presence of missing items, (Pei et al., 2001) proposed fault tolerant (FT) frequent itemsets mining approach. The task of mining FT frequent itemsets from a transactional database can be understand from the following conditions (Pei et al., 2001). •
Multilevel Association Rule in data mining
Multilevel Association Rule : Association rules created from mining information at different degrees of reflection are called various level or staggered association rules. Multilevel association rules can be mined effectively utilizing idea progressions under a help certainty system. Rules at a high idea level may add to good …
