How to refine & improve a #MachineLearning model:  #BigData #DataScience

  • Try increasing lambda (i,e regularization factor) –> to fix High Variance
  • Try smaller set of features –> to fix High Variance
  • You need to be a member of Data Science Central to add comments!
  • First check whether model is suffering from ‘High Bias’ or ‘High Variation’ then try any of the following method to fix the issue.
  • Try adding polynomial features (i.e higher order features) –> to fix High Bias
