Researchers have developed a new interpretable kernel for Gaussian Processes that can model rotational anisotropy in 3D spatial fields. This kernel explicitly parameterizes principal length-scales and orientation, offering a more intuitive approach than standard axis-aligned methods or generic SPD metrics. The method was tested on synthetic data and a material-density dataset, showing improved predictive performance and the ability to reveal complex anisotropy not captured by existing techniques. AI
