  • An MRP Formulation for Supervised Learning: Generalized Temporal Difference Learning Models

    Yangchen Pan, Junfeng Wen, Chenjun Xiao, Philip H.S. Torr

    arXiv · 2024

    This study demonstrates that SL can be reformulated as a problem of interconnected data modeled by an MRP, effectively solved using TD learning, and establishes conditions where TD outperforms ordinary least squares (OLS), and establishes convergence guarantees for the generalized TD algorithm.
