Well, but problem is there is no interpretation. I mean Whats are the acceptance level of MAE, MAE, MAPE, MPE & so on. Without interpretation there is no meaning of memorizing....

thanks for the vid, you made a small mistakes in the first equation when you said that the error = y_hat(predicted value) - y(ground truth), but it's the inverse y - y_hat

Apologies for my lack of knowledge in statistics, great video. For RMSE you mentioned you are squaring it up and then obtaining the square root so its kind of cancelling the effect, if that's the case isn't it same as Mean Absolute Error (MAE)

@MrUlf1337 4 жыл бұрын

as far as i understood it NO. you square the sum of the difference between the actual and predicted values. Then you divide it by the numbers of data points and THEN you take the square root. If you would square something and take the square root immediatly afterwards yes it is the same, but since he divides it by the number of data points it's not the same. If there were brackets around everything underneath the square root and square it then yes it would be the same.

I understand that mathematically they are different operations but conceptually, what is the difference between MAE and RMSE? Why would you choose to use one vs the other?

@aspuzling Жыл бұрын

Ok I read a bit more on the subject and the answer is that the RMSE will be higher than the MAE when your dataset contains a few large errors. So if you want to ensure that you detect outliers then use RMSE. If you want to make sure that you ignore outliers, use MAE.

Wonderful explanation. Why do we don't write units with MAE or RMSE ?

Thanks for the explanation. Good work!

If MAE is 0, then we are concluding that model prediction is perfect. Similarly how is the scale for MSE. what value should MSE have to consider it to be a perfect model?
