WebYou can create a standard network that uses mae with perceptron.. To prepare a custom network to be trained with mae, set net.performFcn to 'mae'.This automatically sets net.performParam to the empty matrix [], because mae has no performance parameters. In either case, calling train or adapt, results in mae being used to calculate performance. WebThe Mean Absolute Error (MAE) is the average of all absolute errors. The formula is: Where: n = the number of errors, Σ = summation symbol (which means “add them all up”), x – x = the absolute errors. The formula may look a little daunting, but the steps are easy: Find all of your absolute errors, x – x. Add them all up.
