I’m confused about the MAPE formula used in the following paper by Numenta:
“Continuous Online Sequence Learning with an UnsupervisedNeural Network Model”
There is no reference to the formula! and it does not look to me reflect the “mean absolute percentage error”! Furthermore, the MAPE that I found in other published papers is as follows:
At is the actual value, Ft is the forecast value, and n denotes the number of samples presented to the network.
Can anyone advice on this please?
