Recipe Objective

With an example, elaborate how to do feature preprocessing using keras

The Keras preprocessing layers API gives an option to developers to build Keras-native input processing pipelines. These pipelines can be used as independent preprocessing code in non-Keras workflows, they can be combined directly with Keras models.

Step 1- Importing Library

import numpy as np import tensorflow as tf from tensorflow.keras.layers.experimental import preprocessing

Step 2- Creating a 2d array.

Preprocessing a 2D array.

X = np.array([[4,8,10], [40,100, 120], [200, 300, 1000],[1000,5000,10000]]) layer = preprocessing.Normalization() layer.adapt(data) normalized_X = layer(X)

Step 3- Printing the mean and Standard Deviation of Data.

print("Features mean: %.2f" % (normalized_X.numpy().mean())) print("Features std: %.2f" % (normalized_X.numpy().std()))
