WebSep 30, 2024 · RMSE: A metric that tells us the square root of the average squared difference between the predicted values and the actual values in a dataset. The lower the RMSE, the better a model fits a dataset. It is calculated as: RMSE = √ Σ(ŷ i – y i) 2 / n. where: Σ is a symbol that means “sum” ŷ i is the predicted value for the i th observation Web机器学习的回归问题常用rmse,mse, mae,mape等评价指标,还有拟合优度r2。由于每次预测出来的预测值再去和原始数据进行误差评价指标的计算很麻烦,所以这里就直接给出他们五个指标的计算函数。
