Hello, is there smoothing in the models their self ?

Hi @marah othman. Do you mean to smooth the input signal or the forecast? No, the library does not have a general smoothing algorithm to pre-process or post-process the data or forecasts. Some models have smoothing-like features, like the pre-defined basis for the

NBEATS

model or the interpolation of the

NHITS

.

yes exactly as preprocessing for data

For most applications it is not necessary, I suggest you to start without this process

okay
