# Metrics ## MSE, Mean Square Error 均方誤差 - 預測值和真實值之間距離的平方和 - 又稱L2 loss - MSE越小,說明預測模型描述實驗資料有更好精確度 - 懲罰偏離值較重 ## RMSE, Root Mean Square Error 均方根誤差 - RMSE vs MSE? ## R-squared ## MAE, Mean Absolute Error 平方絕對誤差 - 又稱L1 loss - 預測值和真實值誤差取絕對值後求平均 ## RMSLE, Root Mean Square Logarithmic Error ## Cross Entropy
