Deconstructing Depreciation: A Dynamic Feature Depreciation Network (DFDN) for Used Automobile Price Valuation

Jasas Mindaugas

Abstract:

  The valuation of used automobiles is a critical economic problem with significant implications for insurers, leasing companies, and individual consumers. While modern Machine Learning (ML) approaches offer superior predictive power, they often lack the interpretability required for trusted financial applications. This paper introduces the Dynamic Feature Depreciation Network (DFDN), a novel neural architecture designed to bridge the gap between econometric transparency and deep learning accuracy. DFDN utilizes a hybrid structure to explicitly model the heterogeneous depreciation rates of vehicle attributes.
