WebMar 29, 2024 · Mean Absolute Error (MAE) is the mean size of the mistakes in collected predictions. We know that an error basically is the absolute difference between the actual or true values and the values that are predicted. The absolute difference means that if the result has a negative sign, it is ignored. Hence, MAE = True values – Predicted values Web1 Content from this work may be used under the terms of the CreativeCommonsAttribution 3.0 licence.
