Researchers have developed several novel AI frameworks for reconstructing complex physical fields from limited sensor data. LASER utilizes a reinforcement learning policy within a latent world model to actively guide sensor placement for optimal data acquisition. Another approach, Cascaded Sensing, employs a hierarchical framework with an autoencoder-diffusion cascade to first resolve structural ambiguity and then refine the field reconstruction. FLUIDSPLAT introduces a sensor-conditioned model using Gaussian primitives for spatially explicit field representation, offering theoretical approximation guarantees. Lastly, MTL-FNO presents a lightweight multi-task Fourier Neural Operator designed for efficient, joint reconstruction of multiple fields while minimizing model size. AI
