Feature Engineering Course


Welcome to the most comprehensive course on feature engineering for machine learning available online.

In this course, you will learn everything you need to preprocess your datasets to train machine learning models like linear regression, logistic regression, decision trees, random forests and gradient boosting machines.


What is feature engineering?

Feature engineering consists in using domain knowledge and statistical methods to create features that make machine learning algorithms work effectively.

Raw data is almost never suitable to train machine learning models. In fact, data scientists devote a lot of effort to data analysis, data engineering and preprocessing, and feature extraction, to create the best features to train predictive models.

Feature engineering includes imputation of missing data, encoding of categorical variables, transformation or discretization of continuous variables, combination of variables, extraction of dates and times, and much more.


What will you learn in this online course?

In this course, you will learn about missing data imputation, encoding of categorical features, numerical variable transformation, discretization, and how to create new features from your dataset.

Specifically, you will learn:

  • How to impute missing values
  • How to encode categorical features
  • How to transform and scale numerical variables
  • How to perform discretization
  • How to remove outliers
  • How to perform feature extraction from dates and time
  • How to create new features from existing ones


And there is more...

You probably saw a lot of courses on other learning platforms like Coursera or Udemy. In fact, this is the full version of the Udemy course. Why is this course special?

While most online courses will teach you the very basics of feature engineering, like imputing variables with the mean or transforming categorical features using one hot encoding, this course will teach you all of that, and much more.

Here, you will first learn the most popular techniques for variable engineering, like mean and median imputation, one-hot encoding, transformation with logarithm, and discretization. Then, you will discover more advanced methods that capture information while encoding or transforming your variables, to obtain better features and improve the performance of regression and classification models.


Advanced methods for feature engineering

These methods include encoding variables with the target mean, using decision trees for discretization or variable combination, combining features mathematically, and automating the procedure of feature creation with a bespoke library: Feature-engine.

You will learn methods described in scientific articles, used in data science competitions like those hosted by Kaggle and the KDD, and that are commonly utilized in organizations. And what’s more, you will easily implement all of these methods by utilizing Python's open-source libraries, like pandas, Scikit-learn, category encoders and Feature-engine.

By the end of the course, you will be able to create end-to-end machine learning workflows that fully transform your datasets and obtain predictions from them.


Feature engineering with Python

Throughout the course, we will use Python as the main language. We will compare the feature engineering implementations of the open-source libraries Pandas, Scikit-learn, Category Encoders and Feature-engine.

Throughout the tutorials, you’ll find detailed explanations of each technique and a discussion about their advantages, limitations, and underlying assumptions, followed by the best programming practices to implement them in Python.

By the end of the course, you will be able to decide which feature engineering technique you need based on the variable characteristics and the models you wish to train. And you will also be well placed to test various transformation methods and let your models decide which ones work best.

Finally, you will be able to create end-to-end machine learning pipelines, packed with feature engineering preprocessing steps that you can easily deploy to production.


Who is this course for?

This course is for data scientists, machine learning engineers and software engineers who want to improve their skills and advance their careers.


Course prerequisites

To make the most out of this course, learners need to have basic knowledge of machine learning, data analytics, and familiarity with the most common predictive models, like linear and logistic regression, decision trees, and random forests.


The instructor

Sole will be guiding you through this course. She’s been selected as Linkedin’s top voice in data science and analytics in 2018 and then again in 2024. She is the author of Packt’s Python Feature Engineering Cookbook and Leanpub’s Feature Selection in Machine Learning book. She is also the maintainer of Feature-engine, an open source Python library for feature engineering and feature selection. With all this experience, who would be better place to teach a course about feature engineering for machine learning? Not that many ;)


To wrap-up

This comprehensive feature engineering course contains over 100 lectures spread across 15 hours of in-demand video, more than 10 quizzes and assessments, demonstrations using real-world use cases, and all topics include hands-on Python code examples in Jupyter notebooks that you can use for reference, practice, and reuse in your own projects.
