The Importance of AI Explainability
Artificial intelligence (AI) and machine learning (ML) are transforming how financial institutions approach many traditional banking processes. When it comes to AI in the financial services industry, the concept of explainability—i.e., the ability to clearly communicate the process behind AI’s decision-making and understand the model’s inner workings—is of the utmost importance.
Some AI is believed to be unexplainable, including generative AI (Gen AI). To accomplish a task, Gen AI can instantly pull from billions of data points, and while it’s theoretically possible to understand this process, the complexity and speed involved makes this quite daunting. This is why AI has, in some circumstances, functioned like a black box—it produced results without explaining the how’s and why’s.
Initially, when users were solely concerned with the accuracy of predictions, the need for explainability didn’t seem pressing. But as AI advances and permeates various sectors, including ones with strict regulatory requirements such as financial services, the need to understand AI’s inner workings has grown immensely.
“Explainability in AI is similar to the transparency required in traditional banking models—both center on clear communication of inputs and outputs,” says Chris Gufford, Executive Director – Commercial Lending at nCino. “Within the model development cycle and data interpretation, explainability is essential for maintaining trust and understanding. At its heart, explainability is about achieving this transparency, regardless of the advanced nature of the AI or the mathematical complexity of the models.”
The demand for explainability only grows as predictive AI becomes more sophisticated. Explainability fosters trust and accountability in AI systems, enhances regulatory compliance, and facilitates model improvement and optimization over time. It empowers stakeholders to make informed decisions based on AI outputs and creates greater understanding and acceptance of AI technology and various domains.
One of the ways companies like nCino ensure explainability is through a concept called “human in the loop.” The concept facilitates ongoing model optimization and refinement, and integrating this concept is crucial for model comprehension and optimization. It involves incorporating human expertise throughout the AI model development, deployment, and execution. Human experts, such as domain specialists or risk analysts, can provide valuable human insights into the data, model assumptions, and business context, which are essential for understanding and interpreting the model’s outputs.
In the model development phase, human experts can collaborate with data scientists to select relevant features, define appropriate model constraints, and validate the model’s performance against real-world scenarios. During model execution, human experts can monitor the model’s behavior and intervene when necessary to address issues such as bias, fairness, or ethical concerns.
As we enter an exciting era where innovation meets efficiency, it is crucial for financial institutions to place explainability and interpretability at the core of their AI models to prioritize transparency, accountability, and human relevance.

Being a leader in the financial services industry requires a seamless approach to innovation and efficiency. One of the crucial elements to success is the integration of automation and augmentation into credit portfolio management, as these tools have the ability to transform operations, manage risk, and improve both banker and client experiences.
Artificial intelligence is revolutionizing many traditional financial services, including credit decisioning. The evolution from traditional statistical models to AI-driven approaches marks a transformative shift in the financial industry. With AI integration, financial institutions will experience a fundamental change in how they assess and manage risk, ushering in a new era of efficiency and innovation.
The rise of artificial intelligence (AI) is transforming how financial institutions (FIs) approach traditional banking processes, but not all FIs are prepared to take advantage of this game-changing technology. Leveraging AI is not a one-off task, but a continuous cycle of assessing, enhancing, and improving data quality for an effective strategy. For this reason, the journey AI optimization can seem daunting.
The mortgage industry has seen some significant changes in recent years with the introduction of digital technology solutions. Organizations are increasingly turning to technology for avenues of competitive advantage, leading many companies into a state of flux as they adjust their business model and digital mortgage strategies to create and maintain profitability with long-term success.
In the rapidly evolving lending landscape, caused in part by the bank failures of 2023, credit portfolios are facing significant stress and heightened challenges, including rising default rates, fluctuating interest rates, and economic uncertainty. Coupled with strict regulatory demands for risk differentiation and portfolio diversification, these pressures are exposing the limitations of current credit portfolio monitoring processes, which are often static, reactive and subjective. As a result, financial institution (FI) leaders are rethinking their credit portfolio management practices.
