Overview of this book

Machine learning is transforming the way we understand and interact with the world around us. This book is the perfect guide for you to put your knowledge and skills into practice and use the Python ecosystem to cover key domains in machine learning. This second edition covers a range of libraries from the Python ecosystem, including TensorFlow and Keras, to help you implement real-world machine learning projects. The book begins by giving you an overview of machine learning with Python. With the help of complex datasets and optimized techniques, you’ll go on to understand how to apply advanced concepts and popular machine learning algorithms to real-world projects. Next, you’ll cover projects from domains such as predictive analytics to analyze the stock market and recommendation systems for GitHub repositories. In addition to this, you’ll also work on projects from the NLP domain to create a custom news feed using frameworks such as scikit-learn, TensorFlow, and Keras. Following this, you’ll learn how to build an advanced chatbot, and scale things up using PySpark. In the concluding chapters, you can look forward to exciting insights into deep learning and you'll even create an application using computer vision and neural networks. By the end of this book, you’ll be able to analyze data seamlessly and make a powerful impact through your projects.

Forecast the IPO Market Using Logistic Regression

In the late 1990s, getting in on the right Initial Public Offering (IPO) was like winning the lottery. First-day returns for some technology companies were many times their initial offering price, and if you were lucky enough to get in on an allocation, you were in for a windfall. Here are a few of the top first-day performers from the period:

  • VA Linux up 697%, 12/09/99
  • up 606%, 11/13/98
  • Foundry Networks up 525%, 9/28/99

While the days of dotcom mania are far behind us, IPOs can still have outsized first-day returns. Here are just a few that rose substantially on their first day of trading in the past year:

  • Bloom Energy up 67%
  • Pinduoduo up 32%
  • Tenable up 32%

As you can see, this is still a market worth paying attention to. In this chapter, we'll take a closer look at the IPO market. We'll see how we can...
