Research-grade applied ML for embodied agents

A short technical note on connecting reward learning, simulation-based training, and safety-critical evaluation for physical AI systems.


Embodied reinforcement learning sits between two requirements that are often treated separately: the objective must encode the right behavior, and the trained policy must survive the deployment distribution.

A useful abstraction is to keep three objects visible:

πθ(as),rϕ(s,a),E(ptrain,pdeploy).\pi_\theta(a \mid s), \qquad r_\phi(s,a), \qquad \mathcal{E}(p_{\mathrm{train}}, p_{\mathrm{deploy}}).

The policy πθ\pi_\theta is the controller, the reward or evaluation model rϕr_\phi defines the learning signal, and E\mathcal{E} is the evaluation protocol that exposes distribution shift between training and deployment.

My research and applied work focus on this interface: inverse RL and imitation learning for objective design, simulation workflows for scalable policy optimization, and robustness experiments that deliberately search for rare failure modes rather than only reporting average-case task performance.
