A prudent blueprint outside of financial services
Model risk refers to the potential for adverse outcomes stemming from models producing incorrect or misleading results. This risk originates not only from design flaws, data inaccuracies, or implementation errors but also significantly from the misuse of models. Misuse can occur when models are applied in contexts for which they were not designed, or when model outputs are interpreted incorrectly or manipulated. In the context of artificial intelligence (AI) and machine learning (ML), model risk encompasses the inaccuracies and uncertainties inherent in models that process and analyze vast datasets to make predictions, decisions, or recommendations. This risk is amplified by the complexity, opacity, and dynamic nature of AI/ML models, making it challenging to predict and quantify the ramifications of model failures accurately.
The impact of Model Risk can extend far beyond mere financial losses, touching on ethical, societal, and safety issues. To pull on an example many are likely familiar with at this point, in the field of automotive engineering, AI and ML models play a central role in the development of autonomous vehicles. These models must accurately interpret sensor data to make split-second decisions regarding vehicle navigation and safety. A failure in these models, such as misinterpreting a stop sign as a yield sign due to flawed training data, could lead to severe accidents, endangering passengers and pedestrians alike.
This sort of example, which can be made for many engineering problems and increasingly in the realm of healthcare, underscore the importance of managing model risk not only to prevent economic losses but also to protect public trust and ensure the ethical and safe application of AI/ML technologies.
MRM is a structured, iterative approach to identifying, assessing, mitigating, and monitoring the risks associated with the use of models. It involves a set of practices designed to ensure models are developed, implemented, and used appropriately, especially in relation to their potential impact on decision-making processes. KPMG outlines a model risk management lifecycle that encompasses six key stages:
Companies outside the financial sector using AI and ML should consider the following:
Broadening the application of model risk management practices is increasingly important in today's technology-driven landscape. By proactively addressing model risk, companies across various industries can enhance the accuracy, reliability, and safety of their AI/ML applications, fostering public trust and ensuring the ethical use of these transformative technologies.
