title: Any way to manually make a variable more important in a machine learning model?
body: <p>Sometimes you know by experience or by some expert knowledge some variable will play a key role in this model, is there a way to manually make the variable count more so the training process can speed up and the method can combine some human knowledge/wisdom/intelligence.</p>
  
  <p>I still think machine learning combined with human knowledge is the strongest weapon we have now</p>
