I Swapped the ML Model in My Android App. The App Had No Idea.
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
IMPACT Demonstrates how interface-driven design can abstract ML model complexity, enabling easier upgrades and maintenance in applications.
