Witryna10 sty 2024 · Step 1: Calculate the similarity scores, it helps in growing the tree. Similarity Score = (Sum of residuals)^2 / Number of residuals + lambda Step 2: Calculate the gain to determine how to split the data. Gain = Left tree (similarity score) + Right (similarity score) - Root (similarity score) Witrynaby impurity atoms (e.g., Zn and Ni) directly doped into the CuO2 planes,2,3 which proved the ability of impurities as a powerful local probe in studying high-Tc superconductivity (HTS). However, there are still some controversies about the mechanism of the impurity resonant state and the modeling of the impurity …
