In the vast world of finance and accounting, ensuring accuracy and preventing fraud is paramount. This blog will guide you through the process of detecting accounting anomalies utilizing Deep Autoencoder Neural Networks. Based on an interactive lab prepared for NVIDIA’s GPU Technology Conference 2018, we will explore how machine learning can unravel the complexities of financial data.

Setting Up Your Environment

Before you dive into detecting anomalies, you need to set up your environment. The lab utilizes Python, IPython Notebook, and PyTorch.

• Navigate to the interactive lab using the following links:
• Run in Binder
• Open in Google Colab

Understanding Deep Autoencoders

Think of a deep autoencoder as a skilled artist creating a replica of a painting. The original painting represents our large-scale accounting data. The autoencoder first tries to capture the essential features of this painting and then reconstructs it to understand the underlying patterns.

In this analogy, any minor discrepancy between the original painting and its replica signifies anomalies in the accounting data. The artist (autoencoder) learns from countless pictures (data points) and gets better over time at spotting imperfections that can suggest fraud or errors.

Key Publication Reference

Our approach is inspired by the work entitled “Detection of Anomalies in Large Scale Accounting Data using Deep Autoencoder Networks” by Marco Schreyer and his colleagues. You can read their publication on arXiv.

Troubleshooting Common Issues

As with any technical endeavor, you may encounter some hiccups along the way. Here are some troubleshooting tips:

• Error while loading the Notebook: Ensure you have a stable internet connection. Try refreshing the page or opening the link in a different browser.
• Environment Issues: Make sure you have installed the necessary libraries such as Torch and other dependencies specified in the lab documentation.
• Performance Problems: Running resource-intensive tasks such as deep learning models can be demanding. Consider using cloud platforms like Google Colab that offer better performance for such tasks.
