Objective

The institution needed to train its AI model to capture nuanced credit risk factors that rigid scoring systems often miss. Their goal was to identify more creditworthy applicants while maintaining strong risk management standards and regulatory compliance.

  • Address shortcomings of traditional credit scoring models
  • Improve recognition of complex income and financial patterns
  • Ensure explainable decisions for every credit determination
  • Reduce bias against underserved segments
  • Streamline manual review bottlenecks

The challenge

Credit risk assessment requires balancing precision with fairness. While automated systems improved speed, they failed to capture context, leaving qualified borrowers behind and regulators unconvinced.

  • Qualified applicants rejected due to rigid criteria
  • Complex self-employment income difficult to assess
  • Regulations requiring explainable AI-driven decisions
  • Bias risks against certain demographic segments
  • Manual review creating costly bottlenecks
  • Previous automation limited to basic pattern matching

CleverX solution

CleverX engaged a panel of credit and compliance experts to train, annotate, and refine the AI system through structured human-in-the-loop supervision.

Expert recruitment:

  • Former bank underwriters with specialized knowledge in non-traditional credit assessment
  • Compliance officers experienced in fair lending practices and regulatory requirements
  • Credit analysts from diverse financial backgrounds including fintech and traditional banking
  • Risk management professionals with expertise in emerging credit products

Training framework development:

  • Created comprehensive annotation guidelines covering edge cases and unusual financial situations
  • Developed decision trees that mirror expert reasoning for complex credit scenarios
  • Built validation protocols ensuring consistency across different expert evaluations
  • Established feedback loops where experts could refine and improve training data quality

Quality assurance protocols:

  • Multi-expert review system for high-stakes credit decisions
  • Regular calibration sessions to maintain consistency in expert judgments
  • Automated checks for regulatory compliance in all training examples
  • Continuous monitoring of model outputs against expert benchmarks

Impact

The training program unfolded in phases, combining large-scale annotation with expert oversight to ensure accuracy and fairness.

Weeks 1-2: Initial expert onboarding and familiarization with client's specific credit products and risk tolerance

Weeks 3-6: Experts annotated thousands of historical credit applications, providing detailed reasoning for approval or denial decisions

Weeks 7-10: Refinement phase where experts reviewed model outputs and corrected misunderstandings

Ongoing: Monthly expert consultations to address new credit products and emerging risk patterns

The supervised fine-tuning taught the model to detect subtle indicators of creditworthiness often overlooked by automated systems, such as improving financial trajectories and industry-specific income patterns.
