Abstract: The widespread adoption of machine learning in credit assessment has raised concerns about algorithmic fairness and discriminatory outcomes affecting protected demographic groups. This paper investigates bias detection methodologies and mitigation techniques designed to promote equitable lending while maintaining predictive accuracy. We analyze three intervention categories: pre-processing data transformations, in-processing algorithmic constraints, and post-processing decision adjustments. Through empirical evaluation on credit datasets, we examine accuracy-fairness trade-offs and assess practical viability for financial institutions under regulatory compliance frameworks. Our comparative analysis demonstrates that mitigation strategies exhibit distinct performance characteristics depending on fairness metrics and business objectives. The findings provide guidance for practitioners balancing the precision of risk assessment with equitable treatment across diverse applicant populations.
