Detection of fraudulent financial papers by picking a collection of characteristics using optimization algorithms and classification techniques based on squirrels
To produce important investment decisions, investors require financial
records and economic information. However, most companies manipulate investors
and financial institutions by inflating their financial statements. Fraudulent
Financial Activities exist in any monetary or financial transaction scenario,
whether physical or electronic. A challenging problem that arises in this
domain is the issue that affects and troubles individuals and institutions.
This problem has attracted more attention in the field in part owing to the
prevalence of financial fraud and the paucity of previous research. For this
purpose, in this study, the main approach to solve this problem, an anomaly
detection-based approach based on a combination of feature selection based on
squirrel optimization pattern and classification methods have been used. The
aim is to develop this method to provide a model for detecting anomalies in
financial statements using a combination of selected features with the nearest
neighbor classifications, neural networks, support vector machine, and
Bayesian. Anomaly samples are then analyzed and compared to recommended
techniques using assessment criteria. Squirrel optimization's meta-exploratory
capability, along with the approach's ability to identify abnormalities in
financial data, has been shown to be effective in implementing the suggested
strategy. They discovered fake financial statements because of their expertise
Un primer acercamiento a un modelo predictivo ajustable por umbrales para detecci贸n de fraudes financieros
El fraude en el sector financiero en transacciones con tarjetas de cr茅dito y d茅bito es un fen贸meno que ha recibido el estudio de la comunidad cient铆fica por su impacto econ贸mico, tanto en individuos como en instituciones. Analizar este problema desde la perspectiva de machine learning es un gran desaf铆o por la poca disponibilidad de transacciones etiquetadas y el desbalanceo en la proporci贸n de clases. En este trabajo exploramos un enfoque alternativo basado en el ajuste del umbral de probabilidad del algoritmo de fraude. A trav茅s de experimentaciones mostramos que este abordaje es eficiente y constituye una alternativa v谩lida para detectar fraude de forma efectiva.Sociedad Argentina de Inform谩tic
Exploring the Perceptions of Accountants on Academic Preparations Related to Occupational Fraud and Internal Control Weaknesses
Occupational fraud and internal control material weaknesses (ICMWs) have become global issues due to the strong correlation between internal control (IC) and fraud revelation. However, academic education (AE) has a positive influence on deliberative reasoning and ethical decisions. Nevertheless, little is known of how accountants perceive their AE prepared them to detect fraud and respond to ICMWs. Thus, there is a need to explore how accountants perceive the strengths and weaknesses in their AE regarding fraud and ICMWs. The study contains a comprehensive review of articles published by peer-reviewed journals, particularly in the last five years. The conceptual framework included the Agency Theory, the Fraud Triangle Theory, the COSO Model, and the Experiential Learning Model (ELM). The method of the research is qualitative with exploratory multiple-case study design. A guarantee of data saturation appeared by conducting thirteen semi-structured, face-to-face interviews with accountants who encountered fraud or ICMWs in work environments. The participants were recruited through a combination of purposive snowball sampling and criterion sampling techniques. Data analysis techniques included open coding, axial coding, content analysis, and cross-case synthesis. Also, data was triangulated by corroborating the findings with evidence from other sources. There are twenty-eight minor themes under eight main themes. Six unique sub-minor themes provided profound findings regarding: (a) educational topics related to anti-fraud, (b) educational methods associated with anti-fraud, (c) educational topics related to IC, (d) educational methods related to IC, and (d) competencies of accounting students (Ass) related to fraud and ICMWs
