Credit Card Fraud Detection Using Asexual Reproduction Optimization
As the number of credit card users has increased, detecting fraud in this
domain has become a vital issue. Previous literature has applied various
supervised and unsupervised machine learning methods to find an effective fraud
detection system. However, some of these methods require an enormous amount of
time to achieve reasonable accuracy. In this paper, an Asexual Reproduction
Optimization (ARO) approach was employed, which is a supervised method to
detect credit card fraud. ARO refers to a kind of production in which one
parent produces some offspring. By applying this method and sampling just from
the majority class, the effectiveness of the classification is increased. A
comparison to Artificial Immune Systems (AIS), which is one of the best methods
implemented on current datasets, has shown that the proposed method is able to
remarkably reduce the required training time and at the same time increase the
recall that is important in fraud detection problems. The obtained results show
that ARO achieves the best cost in a short time, and consequently, it can be
considered a real-time fraud detection system
Actionable Artificial Intelligence for the Future of Production
The Internet of Production (IoP) promises to be the answer to major challenges
facing the Industrial Internet of Things (IIoT) and Industry 4.0. The lack of
inter-company communication channels and standards, the need for heightened safety in Human Robot Collaboration (HRC) scenarios, and the opacity of
data-driven decision support systems are only a few of the challenges we
tackle in this chapter. We outline the communication and data exchange within
the World Wide Lab (WWL) and autonomous agents that query the WWL
which is built on the Digital Shadows (DS). We categorize our approaches into
machine level, process level, and overarching principles. This chapter surveys
the interdisciplinary work done in each category, presents different applications
of the different approaches, and offers actionable items and guidelines for future
work.The machine level handles the robots and machines used for production and
their interactions with the human workers. It covers low-level robot control and
optimization through gray-box models, task-specific motion planning, and opti-
mization through reinforcement learning. In this level, we also examine quality
assurance through nonintrusive real-time quality monitoring, defect recognition,
and quality prediction. Work on this level also handles confidence, verification,
and validation of re-configurable processes and reactive, modular, transparent
process models. The process level handles the product life cycle, interoperability and analysis and optimization of production processes, which is overall attained
by analyzing process data and event logs to detect and eliminate bottlenecks
and learn new process models. Moreover, this level presents a communication
channel between human workers and processes by extracting and formalizing
human knowledge into ontology and providing a decision support by reasoning
over this information. Overarching principles present a toolbox of omnipresent
approaches for data collection, analysis, augmentation, and management, as well
as the visualization and explanation of black-box models
