title: ML.NET - ForecastBySsa
body: <p>I'm evaluating and testing ForecastBySsa and I'm not really impressed with the result.</p>
  
  <p>1) Example from Microsoft</p>
  
  <p><a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.ml.timeseriescatalog.forecastbyssa?view=ml-dotnet" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/dotnet/api/microsoft.ml.timeseriescatalog.forecastbyssa?view=ml-dotnet</a></p>
  
  <p>The example show a time series of 5 data points, repeated 3 times with values 0,1,2,3,4.</p>
  
  <p>The forecasted next five values are:
  // Forecasted values: // [1.977226, 1.020494, 1.760543, 3.437509, 4.266461]</p>
  
  <p>Hmm... Why 1.97? Far from zero. And overall - not that good?</p>
  
  <p>2) Testing with airline passenger data dataset</p>
  
  <p>Testing the algorithm with data from:

  <p>And get the following forecast</p>

  <p>Questions:</p>
  
  <p>a) Anyone having good forecasting results using ML.NET ForecastBySsa?</p>
  
  <p>b) Anyone having a good example with some real dataset and parameters etc?</p>
