Neural Network Projects with Python

By: James Loy

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.

Feature engineering

As briefly discussed in the previous chapter, Chapter 2, Predicting Diabetes with Multilayer Perceptrons feature engineering is the process of using one's domain knowledge of the problem to create new features for the machine learning algorithm. In this section, we shall create features based on the date and time of pickup, and location-related features.

Temporal features

As we've seen earlier in the section on data visualization, ridership volume depends heavily on the day of the week, as well as the time of day.

Let's look at the format of the pickup_datetime column by running the following code:

print(df.head()['pickup_datetime'])

We get the following output:

Recall that neural...
