TRI's latest Large Behavior Model (LBM) paper landed on arxiv last night! Check out our project website: toyotaresearchinstitute.gith… One of our main goals for this paper was to put out a very careful and thorough study on the topic to help people understand the state of the technology, and to share a lot of details for how we're achieving it. youtube.com/watch?v=BEXFnru5…

I'm excited to share new optimality conditions for nonlinear stochastic optimal control, and the first indirect shooting method for solving these problems! 📖 arxiv.org/abs/2502.06726 💡 How? Using rough path theory ⬇️

3/4) As an application, we propose the first indirect shooting method for nonlinear stochastic optimal control: It converges much faster than a direct method on a regulation task. Why? Because it only searches over the initial conditions of the adjoint vector 💡

4/4) This work combines known pathwise approaches to SDEs from the mathematics & machine learning communities and ideas from indirect optimal control. We use proof techniques developed by Pontryagin and recent integrability results on rough paths (Cass, Friz, et al. ~2013).
