Once we have the SSE and SST values, we can substitute them into the formula to calculate the R² score. The result will be a value between 0 and 1, indicating the proportion of variability in the dependent variable that can be explained by the independent variables.©...

回归模型的性能的评价指标主要有:RMSE(平方根误差)、MAE(平均绝对误差)、MSE(平均平方误差)、R2_score。但是当量纲不同时,RMSE、MAE、MSE难以衡量模型效果好坏。这就需要用到R2_score,实际使用时,会遇到许多问题,今天我们深度研究一下。预备知识搞清楚R2_score计算之前,我们还需要了解几个统计学概念。若用$y_i$表...

回归问题常用的评估指标包括:MAE, MAPE, MSE, RMSE, R2_Score等。 这些评价指标基本都在 sklearn 包中都封装好了,可直接调用。 安装sklearn, 完整的名字是scikit-learn。 pipinstall-Uscikit-learn# 现在最新版是 V0.22.2.post1 注: MAPE 在V0.22.2中还不能直接调用,预计会在V0.23中发布; ...
Hello, The r2_score metric is something that many functions in sklearn use but right now I think it generally is set as 1 - RSS/SYY, which would the right formula to use if you run a regression with an intercept. If you did not use this, however, and ran a regression with no int...
