Learning for CasADi: Data-driven Models in Numerical Optimization
CoRR(2023)
摘要
While real-world problems are often challenging to analyze analytically, deep
learning excels in modeling complex processes from data. Existing optimization
frameworks like CasADi facilitate seamless usage of solvers but face challenges
when integrating learned process models into numerical optimizations. To
address this gap, we present the Learning for CasADi (L4CasADi) framework,
enabling the seamless integration of PyTorch-learned models with CasADi for
efficient and potentially hardware-accelerated numerical optimization. The
applicability of L4CasADi is demonstrated with two tutorial examples: First, we
optimize a fish's trajectory in a turbulent river for energy efficiency where
the turbulent flow is represented by a PyTorch model. Second, we demonstrate
how an implicit Neural Radiance Field environment representation can be easily
leveraged for optimal control with L4CasADi. L4CasADi, along with examples and
documentation, is available under MIT license at
