sMAPE Calculation

[kurtulusbulus]

Hi,

Thank you for the post! It is great work!

I was wondering if you could check your sMAPE calculation in the notebook. It seems not correct. In My calculation it gives higher value than yours.

Best,
Kurtulus

No disrespect but his formula is wrong. He has
np.mean(abs(outputs[i]-targets[i])/(targets[i]+outputs[i])/2)

The right formula is
np.mean(abs(outputs[i]-targets[i])/((targets[i]+outputs[i])/2))

he is missing brackets
