Detecting Telecommunication Fraud with Visual Analytics: A Review

Abstract: The detection of anomalous events in large multivariate data is sought in many domains. Analysis of data is an important fraud detection procedure in detecting suspicious events and prevent attempts to defraud. While now the data is becoming more complicated and difficult as data scales and complexities increase than ever before, the rich insights within the data may be difficult to identify by traditional means and often remain hidden. People require powerful tools to extract valid conclusions from the data w… Show more

“…The visual analytics model often used to detect fraud is heat maps (Singh and Best, 2016; Leite et al , 2018; Amin et al , 2020). Moreover, Aldhizer (2017) explains that this model provides a graphical representation of different data elements, such as the perceived level of fraud risk in the client’s business processes based on the probability of occurrence and the level of materiality.…”

“…Both frameworks sort the outliers by relevance and then identify a subset of features to optimize the feature selection process. Others have used visualization techniques to discover sequential patterns in CCF transactions (Carcillo et al , 2018; Amin et al , 2020). The idea behind sequential pattern analysis is to discover hidden patterns by clustering the data into groups and then identify the outlying observations that may not be possible to make through traditional statistical queries.…”
