Pre-processing

  • Data exploration (clean-up)
  • Data transformation
  • Outlier detection and removal
  • Data normalization, one of:

    • Zscore Normalization, in Zscore normalization, the input variable data is converted into zero mean and unit variance.
    • Sigmoidal Normalization, sigmoidal normalization is a nonlinear transformation. It transforms the input data into the range -1 to 1, using a sigmoid function
  • Data analysis
  • Validation of results
