MathOptAI.jl: Embed trained machine learning predictors into JuMP models

arXiv:2507.03159v2 Announce Type: replace Abstract: We present \texttt{MathOptAI.jl}, an open-source Julia library for embedding trained machine learning predictors into a JuMP model. \texttt{MathOptAI.jl} can embed a wide variety of neural networks, decision trees, and Gaussian Processes into a larger mathematical optimization model. In addition to interfacing a range of Julia-based machine learning libraries such as \texttt{Lux.jl} and \texttt{Flux.jl}, \texttt{MathOptAI.jl} uses Julia's Python interface to provide support for PyTorch models. When the PyTorch support is combined with \texttt

Why this matters
Why now

The proliferation of AI models across engineering and scientific domains necessitates tools for their transparent and optimizable integration into existing mathematical frameworks.

Why it’s important

This development enables machine learning models to be embedded directly into optimization problems, making AI outputs verifiable, controllable, and subject to hard constraints, crucial for high-stakes applications.

What changes

Machine learning predictors can now be treated as first-class components within mathematical optimization models, moving beyond simple prediction to integrated decision-making.
