      Analysis

      This paper introduces a novel learning-based framework, Neural Optimal Design of Experiments (NODE), for optimal experimental design in inverse problems. The key innovation is a single optimization loop that jointly trains a neural reconstruction model and optimizes continuous design variables (e.g., sensor locations) directly. This approach avoids the complexities of bilevel optimization and sparsity regularization, leading to improved reconstruction accuracy and reduced computational cost. The paper's significance lies in its potential to streamline experimental design in various applications, particularly those involving limited resources or complex measurement setups.

      Analysis

      This paper addresses a significant challenge in physics-informed machine learning: modeling coupled systems where governing equations are incomplete and data is missing for some variables. The proposed MUSIC framework offers a novel approach by integrating partial physical constraints with data-driven learning, using sparsity regularization and mesh-free sampling to improve efficiency and accuracy. The ability to handle data-scarce and noisy conditions is a key advantage.
