“…For this, we use Word2Vec applied to the sequences of discrete values taken by the feature for all card-holders as proposed in Russac et al (2018). Each value of a categorical feature f is finally translated into a vector Ghosh et al, 2020).…”

“…Besides the raw features, we additionally use aggregated features (Bahnsen et al, 2016;Jurgovsky et al, 2018;Ghosh et al, 2020). This serves as a feature engineering method to capture the past context of a card-holder.…”

“…These observations are so unique as to arouse the suspicion that they were generated owing to illegal acts or undetected errors. To reveal the critical information in them, many outlier detection technologies have been studied and used in various applications, such as fraud detection in credit card transactions [8,11,39] or taxes [17,19], identifying false information on e-commerce platforms [12,30] or social media [23,40,42], intrusion detection in network service requests [35,38], and detecting abnormal trajectories during traic monitoring [4,34].…”

“…The traditional paradigm of fraud detection solutions in financial institutions consists of formulating it as a classification problem with a focus on improving the fraud recall rates of these classification models. Several papers in the literature have proposed different methods for creating robust features that are immune to model/concept drift using statistical, deep learning, and unsupervised techniques ( [27], [4], [46], [2], [9]). However, these methods of problem formulation ignore a number of issues:…”
