Just a note: the “expected outputs” have no value unless the tasks are more precisely specified, e.g. how much of the series is to be used for training / validation (…should be multiples of the period underlying period according to the lecture, but isn’t in the solution, which makes it extra hard to guess…), how many samples to compute the moving averages over etc.

Sorry for addressing this so late!

Can you please elaborate on what exactly is your point sir

Thanks
