05/15/2023, 3:50 PMI ran the following code multiple times -
nhits = NHITS(h=56,
input_size=560,
max_steps=1,
random_seed=42,)
fcst = NeuralForecast(models=[nhits],freq='D')
fcst.fit(df=train_fin)
pred_nhits = fcst.predict(random_seed=42)
I ended up getting the same error percentage when comparing predictions and actuals for the next 56 days: 36.01%
When I ran the following code multiple times -
nhits = NHITS(h=56,
input_size=560,
max_steps=100,
random_seed=42,)
fcst = NeuralForecast(models=[nhits],freq='D')
fcst.fit(df=train_fin)
pred_nhits = fcst.predict(random_seed=42)
I get different error percentages each time as the predictions are different each time. However the error percentages are quite low ranging between 0.1 to 2%. Model does really well!
It would be very helpful if you can recommend a way I can get stable results as well as lower error rates. Thankyou!
