The Art of Data-Driven Business

By: Alan Bernardo Palacio

Overview of this book

One of the most valuable contributions of data science is toward helping businesses make the right decisions. Understanding this complicated confluence of two disparate worlds, as well as a fiercely competitive market, calls for all the guidance you can get. The Art of Data-Driven Business is your invaluable guide to gaining a business-driven perspective, as well as leveraging the power of machine learning (ML) to guide decision-making in your business. This book provides a common ground of discussion for several profiles within a company. You’ll begin by looking at how to use Python and its many libraries for machine learning. Experienced data scientists may want to skip this short introduction, but you’ll soon get to the meat of the book and explore the many and varied ways ML with Python can be applied to the domain of business decisions through real-world business problems that you can tackle by yourself. As you advance, you’ll gain practical insights into the value that ML can provide to your business, as well as the technical ability to apply a wide variety of tried-and-tested ML methods. By the end of this Python book, you’ll have learned the value of basing your business decisions on data-driven methodologies and have developed the Python skills needed to apply what you’ve learned in the real world.

Working with more product features

In the example, we will use a dataset that contains many more features than the previous example. In this case, we will simulate data obtained from a crisp retail vendor that has asked some of its customers to rank its products according to their level of preference:

  1. The following block of code will read the dataset, which is a CSV file, and will prompt us with the result:
    # Load data
    conjoint_dat = pd.read_csv('/content/conjoint_data.csv')

This results in the following output:

Figure 4.9: Crisps data

  1. We can see that the data contains only categorical values, so it will be necessary to transform this categorical data into a one-hot vector representation using the get_dummies pandas function, which is what we do in the next block of code:
    conjoint_dat_dum = pd.get_dummies(conjoint_dat.iloc[:,:-1], columns = conjoint_dat.iloc[:,:-1].columns)

We can see that now...
