This video lecture provides an introduction to deep learning in accounting and auditing. The speaker, Marco, discusses the applications of deep learning techniques in financial auditing and fraud detection, explaining the differences between artificial intelligence, machine learning, and deep learning. The lecture includes practical sessions demonstrating the fine-tuning of large language models and the training of auto-encoder neural networks using Google Colab and GPUs.
This lecture by Marco provides a comprehensive overview of deep learning and its applications within the fields of accounting and auditing. The speaker begins by establishing context, explaining the fundamental differences between artificial intelligence (AI), machine learning (ML), and deep learning (DL). He highlights the limitations of traditional, rule-based systems in detecting sophisticated financial fraud, using his experience at PricewaterhouseCoopers investigating money laundering schemes as a compelling example. He emphasizes that these traditional methods often rely heavily on pre-defined rules and human feature engineering, making them inflexible and less effective against evolving fraud techniques.
The core of the lecture centers on how deep learning overcomes these limitations. Marco explains that DL's strength lies in its ability to learn complex representations directly from raw data ("end-to-end learning"), eliminating the need for extensive manual feature engineering. He illustrates this with examples from image recognition, showing how DL models can automatically identify relevant features at multiple levels of abstraction, unlike traditional methods which require human experts to define these features beforehand.
The lecture then introduces several cutting-edge deep learning paradigms:
The lecture uses illustrative examples like AlphaGo (mastering Go) and AlphaFold (predicting protein structures) to showcase DL's capabilities and the reasons for its recent success. These successes hinge on three factors: the availability of vast datasets ("big data"), algorithmic advancements in neural network architectures, and the increased accessibility of high-performance computing (specifically GPUs) that make training these complex models feasible. Marco specifically promotes the use of cloud-based platforms like Google Colab as a cost-effective way to access these resources. The lecture concludes with a motivational video showcasing a robotic hand learning to solve a Rubik's Cube using DL, emphasizing the power of learning over explicit programming.
These takeaways offer a strong foundation for applying the knowledge gained from the lecture to address problems or improve processes in accounting and auditing. The specific problems you choose to address in your assignment should reflect how these deep learning capabilities can create more efficient and effective practices within the field.
