Standardize A Feature

Preliminaries

# Load libraries
from sklearn import preprocessing
import numpy as np

Create Feature

# Create feature
x = np.array([[-500.5], 
              [-100.1], 
              [0], 
              [100.1], 
              [900.9]])

Standardize Feature

# Create scaler
scaler = preprocessing.StandardScaler()

# Transform the feature
standardized = scaler.fit_transform(x)

# Show feature
standardized
array([[ 0.        ],
       [ 0.28571429],
       [ 0.35714286],
       [ 0.42857143],
       [ 1.        ]])
