Behavioral Heterogeneity as Quantum-Inspired Representation
🤖 AI Summary
This work proposes a novel quantum-inspired approach to modeling driver heterogeneity by representing latent behavioral states through density matrices, thereby capturing their dynamic evolution over time. Unlike traditional methods that reduce driver heterogeneity to static labels or discrete modes, the proposed framework integrates nonlinear random Fourier feature embeddings of observational data with a context-aware and temporally persistent profile activation mechanism. This enables a more nuanced characterization of how driving behaviors adapt and transition in response to varying conditions. Evaluated on the real-world TGSIM driving dataset, the method successfully extracts and analyzes dynamic driver profiles, demonstrating both the effectiveness and innovation of the framework in accurately representing the complex, evolving nature of driver heterogeneity beyond the constraints of static classification paradigms.

📝 Abstract
Driver heterogeneity is often reduced to labels or discrete regimes, compressing what is inherently dynamic into static categories. We introduce quantum-inspired representation that models each driver as an evolving latent state, presented as a density matrix with structured mathematical properties. Behavioral observations are embedded via non-linear Random Fourier Features, while state evolution blends temporal persistence of behavior with context-dependent profile activation. We evaluate our approach on empirical driving data, Third Generation Simulation Data (TGSIM), showing how driving profiles are extracted and analyzed.
