Associating Absent Frequent Itemsets with Infrequent Items to Identify Abnormal Transactions
Data stored in transactional databases are vulnerable to noise and outliers and are often discarded at the early stage of data mining. Abnormal transactions in the marketing transactional database are those transactions ...
Effects of graph embellishments on the perception of system states in mobile monitoring tasks
Monitoring of critical systems such as large server parks require suitable visualization tools that draw the attention to essential aspects of system state to ensure continuous operation. Moreover, administration is ...
Measuring 2D:4D finger length ratios with Smartphone Cameras
(IEEE Press, 2014-10)
Finger length ratios have received much attention among researchers as the 2D:4D ratio has been linked to several physical and mental characteristics. This study explores the feasibility of using a Smartphone as an ...
Evolutionary optimization algorithms for sunlight-based positioning sensor networks
(Hindawi Publishing Corporation, 2014)
The sunlight intensity-based global positioning system (SGPS) is able to geolocate outdoor objects by means of the sunlight intensity detection. This paper presents the integration of SGPS into a sensor network in order ...
An efficient particle swarm optimizer with application to Man-Day project scheduling problems
(Hindawi Publishing Corporation, 2014-05-06)
The multimode resource-constrained project scheduling problem (MRCPSP) has been confirmed to be an NP-hard problem. Particle swarm optimization (PSO) has been efficiently applied to the search for near optimal solutions ...
