Standard Chartered partners with Truera to tackle unjust bias in AI-supported decision making
Standard Chartered presented a challenge to the Truera team, to help create a solution that gives greater insight into the machine learning decision making process.
Standard Chartered has collaborated with US-based startup Truera, to use its model intelligence platform to improve model quality and increase trust by analysing models and helping to identify and eliminate unjust biases in the decision-making process.
Machine learning, which makes it quicker and easier to analyse large amounts of data and identify patterns and trends, leads to better performance and risk management when used correctly. However, because machine learning models are built using complex automated algorithms, they can act like a black box where it is often challenging for data scientists to explain in detail how decisions are made, and validation of a model’s effectiveness can take longer.
Mindful to ensure that data is used ethically, and with a vision to scale up their use of machine learning for core credit decisioning across multiple markets, Standard Chartered presented a challenge to the Truera team, to help create a solution that gives greater insight into the machine learning decision making process, including being able to identify, and therefore mitigate, unjust bias.
Truera collaborated closely with the Bank’s retail analytics, risk, digital and technology teams on a pilot that focused on one of the Bank’s challenger credit decisioning algorithms which uses a combination of traditional data, and with clients’ consent, alternative data.
A solution that has been developed works across multiple machine learning platforms and is able to pinpoint the specific variables that influence risk scoring. It also has the ability to look for correlations between seemingly impartial variables that can act as proxies for demographic indicators such as race or gender, which could lead to the introduction of unjust bias resulting in unfair decisions.
The Bank will now work with Truera to further develop the software and explore its application across a range of AI use cases.
Vishu Ramachandran, Group Head, Retail Banking, Standard Chartered, said: “Ensuring transparency and explainability in AI-based decision making is not just a competitive advantage for us, but also the right thing to do by our clients. Our partnership with Truera will help us better explain and justify our models, support us in building a stronger and more sustainable business as well as give confidence to both customers and regulators in the fairness of our data-driven processes and outcomes”.
