The author details how they successfully replaced the machine learning model in their Android application, FinRisk, without altering the existing codebase. This was achieved through an interface-driven design that allowed the new neural network model to seamlessly replace the old logistic regression model. The upgrade was prompted by the original model's inability to correctly classify a specific edge case involving high income and high debt, a limitation inherent in its architecture. AI
