Higher-Order Geometric Updates for Levenberg-Marquardt Method via Riemann Normal Coordinates

A Riemann-normal-coordinate Levenberg-Marquardt method (RNC-LM), which eliminates the tangential component of residual acceleration order by order in a moving tangent frame, making the actual objective reduction more consistent with the linear model prediction of LM.
