Point 1: Data-driven inversion algorithm capable of reproducing sharp boundaries without excessive reliance on prior information

We have developed a new inversion algorithm that can accurately depict sharp resistivity boundaries. This data-driven approach represents a significant advancement by minimizing reliance on prior assumptions about boundary locations.

Accurately depicting sharp resistivity boundaries is crucial for improving the precision of resource exploration, particularly for metallic deposits. This method can be implemented by incorporating an ABIC search into existing inversion codes, and we hope it will be adopted across many platforms in the future.
