Learning Modules
1. The Anatomy of an Enterprise Agent
How RAG, vector databases, and tools allow agents to operate on credit union data without model retraining.
- Retrieval-Augmented Generation (RAG) is the gold standard for secure AI. Instead of teaching the model your policies, RAG searches your secure files first, copies the relevant text, and feeds it to the AI as a reference.
- Vector Databases act like index books, converting documents into mathematical vectors to quickly find conceptually matching information.
- Tool Integrations (APIs) allow agents to read core banking systems, call credit bureaus, or calculate debt-to-income (DTI) ratios.
An underwriting agent automatically reviews an auto loan application, pulls the credit bureau score, searches the internal lending handbook for rate criteria, calculates the DTI, flags exceptions, and outputs a clean recommendation report for the human underwriter.
2. Regulatory Compliance & Fair Lending (BSA/AML/NCUA)
Navigating safety, fairness, and explainability requirements in automated decisions.
- Fair Lending regulations require that credit decisions be non-discriminatory. If an AI agent recommends declining a loan, the reasoning must be clear, explainable, and free of bias.
- Audit Trails: Every step the agent took (which policy it searched, what credit score it read, what calculation it performed) must be recorded in an immutable log for internal audits and NCUA examinations.
- Vendor Due Diligence: You must ensure that third-party AI systems encrypt data in transit and at rest, and adhere to strict SOC 2 type II security standards.
The NCUA actively examines how credit unions handle automated and algorithmic tools. Management must be able to explain the inputs, variables, and boundaries of any AI model used in lending or risk scoring.
3. Human-in-the-Loop (HITL) Architecture
Designing AI workflows that combine agent efficiency with human judgment.
- HITL is an architectural pattern where the AI does not have full autonomy. It conducts research, drafts recommendations, and waits for a human click before executing high-risk commands.
- High-Risk Triggers: Actions like executing wire transfers, changing interest rates, final loan approvals/denials, and sending official regulatory disclosures MUST require human approval.
- Human review acts as a secondary buffer, catching hallucinations, biases, or tool malfunctions before they affect members.
