5. Introduction Neural Networks not widely used in audit Used mainly in science, and has some applications for fraud detection Has been tested and proposed for various uses in accounting and auditing
6. Background Neural networks are a type of artificial intelligence, and are based on the structure of the human brain and are composed of a large number of interconnected processors Pattern recognition is one of the most important aspects of the neural network technology The main advantage of artificial neural networks is that they can learn from their inputs and examples that are inputted into them can see relationships in data that will not be noticeable to human observers
8. History In 1994, neural networks were a new type of technology In 2003, large companies began to implement neural networks Robert Hecht-Nielsen, a professor at the University of California, San Diego, called neural networks “the most important scientific challenge of our time”
9. Current State of Neural Networks in Auditing Neural networks have been used in various applications across the scientific world, but they have not seen widespread implementation in the areas of accounting and auditing This section will examine the application of neural networks in various areas
10. Continuous Auditing Continuous auditing is defined as a type of auditing which produces audit results simultaneously, or a short period of time after, the occurrence of relevant events Internal auditors have a very prominent role in continuous auditing of a company Training efforts should have sufficient depth
11. Fraud Detection Neural networks have become the method of choice in the realm of fraud detection For example, a study used a neural network system to identify possible areas in financial data that would lead to fraud lawsuits The model will be able to assess this probability of fraud litigation
12. Accounting Buried deep within accounting data are patterns Accounts that traditionally are not viewed as having strong correlations with each other may in fact present substantial relationships
13. Auditor Decisions Many parts of the auditing field have been subject to neural network testing The two duties that stand out in terms of importance are the evaluation of a going concern opinion, and issuing qualified opinions in audit reports
14. Going Concern Being able to forecast earnings would allow for auditors to see if a company is likely to be able to continue as a going concern, and neural networks can establish patterns to see financial viability in the future No matter how many inputs are put into the system, and what the system generates as an output, it is still ultimately the auditor’s decision in the end
15. Qualified Opinions Being able to determine predictive patterns with regards to qualified audit opinions would allow auditors to “plan specific auditing procedures to achieve an acceptable level of audit risk” Large amounts of data could be used to focus auditors’ attention on possible problem areas that may result in a qualified opinion, and allow for a greater degree of testing and analysis with regards to these problem areas
16. Improvements? Their current lack of usage by the auditing profession should be reassessed The large amount of studies being performed over the past ten years is evidence of a growing number of academics and professionals who believe that this technology can provide great benefits to the auditing community
17. Cost Effective? It will become increasingly necessary to keep up by employing neural networks to observe patterns that are beyond the ability of human auditors Employing neural networks would also lead to a greater degree of accuracy in dangerous situations If auditors are not able to have a tool on their side that can generate predictive data about these issues, then they may not be able to keep pace with their own profession
18. Recommendations It is recommended that in the presence of evolving technology, a neural network model should be implemented into usage by auditing professionals Using the system would likely require a full-time commitment The neural network would have to be applied to each audit on an individual basis, so once a firm implements the necessary infrastructure for the network, individual audits can be analyzed
19. Conclusion Their specific application to various issues within the auditing world, such as continuous auditing, fraud detection, auditor decision making (going concern evaluation as well as issuing qualified audit opinions) could change the entire profession It is important for the auditing world to see that neural networks are not a replacement for the expertise and professional judgment of auditors, but simply a means of directing their attention and recognizing patterns in large amounts of data that humans would not see
