Overview of this book

Neural networks are at the core of recent AI advances, providing some of the best resolutions to many real-world problems, including image recognition, medical diagnosis, text analysis, and more. This book goes through some basic neural network and deep learning concepts, as well as some popular libraries in Python for implementing them. It contains practical demonstrations of neural networks in domains such as fare prediction, image classification, sentiment analysis, and more. In each case, the book provides a problem statement, the specific neural network architecture required to tackle that problem, the reasoning behind the algorithm used, and the associated Python code to implement the solution from scratch. In the process, you will gain hands-on experience with using popular Python libraries such as Keras to build and train your own neural networks from scratch. By the end of this book, you will have mastered the different neural network architectures and created cutting-edge AI projects in Python that will immediately strengthen your machine learning portfolio.

Data preprocessing

In the previous section, Exploratory data analysis, we have discovered that there are 0 values in certain columns, which indicates missing values. We have also seen that the variables have different scales, which can negatively impact model performance. In this section, we will perform data preprocessing to handle these issues.

Handling missing values

First, let's call the isnull() function to check whether there are any missing values in the dataset:

print(df.isnull().any())

We'll see the following output:

It seems like there are no missing values in the dataset, but are we sure? Let's get a statistical summary of the dataset to investigate further:

print(df.describe())

The output is as...
