It is an elemental analysis technology developed based on the basic principle that the wavelength of atomic spectrum and ion spectrum has a one-to-one correspondence relationship with specific elements.

Mining enterprises should strengthen information disclosure, regularly release ESG reports to the public, and accept social supervision.

Gaussian Process Regression (GPR) offers a different approach. As a probabilistic, non-parametric method, GPR not only provides the predicted mean, but also directly quantifies prediction uncertainty through the posterior variance. This capability is particularly valuable for engineering decision-making and experimental design, where understanding uncertainty can be as important as the prediction itself.
