Business Problem

A financial institution faced challenges in loan approvals due to data scarcity and reliance on traditional models, resulting in high rejection rates and extended processing times. These inefficiencies impacted customer satisfaction and financial performance. To resolve this, the institution collaborated with GoML to implement an AI-driven solution that leverages synthetic data from rejected loan applications, enhancing the accuracy and efficiency of loan approval models.

  • Data Limitations: The institution's existing loan approval models were limited by incomplete or biased datasets that could not account for diverse customer profiles.
  • Model Accuracy: The traditional models showed inconsistencies in predicting loan approvals, resulting in a significant number of false positives and false negatives.
  • Increased Processing Times: Lack of reliable data caused delays in decision-making, increasing operational costs.
  • High Rejection Rates: Many potentially approvable applications were rejected due to the inadequacies in the model's performance, leading to lost opportunities and customer dissatisfaction.

Solution

GoML introduced a Real-Time Synthetic Data Generation model powered by Generative AI to generate synthetic data based on patterns from rejected loan applications. By synthesizing and analyzing the data from previously rejected applicants, GoML's solution created high-quality, realistic datasets to fine-tune the institution's loan approval algorithms.

Data Enrichment
By synthesizing data from rejected loan applications, the model enhanced the coverage of data points such as income trends, credit history variations, and employment patterns.

Pattern Identification
The solution uncovered latent patterns that were previously overlooked, offering a new perspective on customer profiles and their eligibility for loans.

Real-Time Data Simulation
The AI engine allowed the institution to simulate multiple scenarios using synthetic data to predict approval rates, reducing the need for historical data.
