Neural networks
Pre-processing
- Data exploration (clean-up)
- Data transformation
- Outlier detection and removal
- Data normalization, one of:
- Min-Max Normalization, min-max normalization is a linear scaling algorithm. It transforms the original input range into a new data range (typically 0-1).
- 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
