This paper presents a comprehensive framework for enhancing AI model interpretability in financial risk assessment through contrastive time series visualization techniques. Financial institutions increasingly deploy complex AI models for risk assessment, yet these models often function as "black boxes," creating significant interpretability challenges for analysts and regulatory compliance issues. We propose a novel approach that combines information theory-based visualization methods with interactive contrastive visual analytics to reveal critical temporal patterns driving model decisions. Our methodology integrates visual perception principles, entropy-based temporal importance weighting, and dimensionality reduction techniques optimized for financial time series data. The framework enables direct visual comparison between normal patterns and anomalies, highlighting feature attribution differences and decision boundaries across varying risk scenarios. Empirical evaluation across multiple financial use cases demonstrates substantial improvements in analyst decision time (42.2%), inter-analyst agreement (24.4%), and anomaly detection rates (34.8%). Implementation considerations address computational efficiency challenges for large-scale financial datasets while maintaining sub-100ms response times for interactive exploration. The approach bridges the gap between statistical model outputs and domain-specific financial knowledge, providing both global explanations of model behavior and contextual interpretations of specific predictions.
