A CC BY 2025 Sensors review reports learned mocap recovery overfits benchmarks (CMU, HDM05) and degrades on long gaps and new subjects, clothing or marker sets, while classical interpolation is simple and interpretable but relies on manual input; it cites tree-based regression for long gaps. Method-level claims are secondary.
