What is a good MAE score? (simply explained) - Stephen Allwright

Webb28 aug. 2024 · The closer MAE is to 0, the more accurate the model is. But MAE is returned on the same scale as the target you are predicting for and therefore there isn’t a general rule for what a good score is. How good your score is can only be evaluated within your dataset. MAE can, however, be developed further by calculating the MAPE (Mean … Webbfrom sklearn.datasets import load_iris, load_diabetes: from sklearn.model_selection import train_test_split: from sklearn.neighbors import KNeighborsClassifier, KNeighborsRegressor: from sklearn.metrics import accuracy_score, mean_squared_error, mean_absolute_percentage_error: from abc import ABC, abstractmethod: from scipy …
