# Inverse Dynamics Learning

Inverse dynamics learning addresses the modeling of the mapping from robot states and accelerations to actuator torques or wrenches, enabling advanced control, adaptation, and model-based planning in robotics and biomechanics. Accurate inverse dynamics models enable precise tracking, impedance or computed-torque control, and facilitate both skill transfer as well as human motion analysis. The field combines principles from rigid-body dynamics, regression, nonparametric statistics, kernel methods, meta-learning, and deep learning, while aspiring to meet challenges in real-time adaptation, uncertainty quantification, compliance, and data efficiency. This article provides a rigorous exposition of key methodologies, hybrid modeling frameworks, probabilistic approaches, adaptive control integration, and critical experimental results, with all claims and algorithms substantiated in the provided primary literature.

## 1. Formal Statement of the Inverse Dynamics Problem

The inverse dynamics problem seeks a function $f: (q, \dot{q}, \ddot{q}) \mapsto \tau$ that maps the configuration $q \in \mathbb{R}^n$, velocity $\dot{q}$, and acceleration $\ddot{q}$ of an $n$-DOF manipulator to a vector of joint torques $\
