Causal Inference and Discovery in Python

Overview of this book

Causal methods present unique challenges compared to traditional machine learning and statistics. Learning causality can be challenging, but it offers distinct advantages that elude a purely statistical mindset. Causal Inference and Discovery in Python helps you unlock the potential of causality. You’ll start with basic motivations behind causal thinking and a comprehensive introduction to Pearlian causal concepts, such as structural causal models, interventions, counterfactuals, and more. Each concept is accompanied by a theoretical explanation and a set of practical exercises with Python code. Next, you’ll dive into the world of causal effect estimation, consistently progressing towards modern machine learning methods. Step-by-step, you’ll discover Python causal ecosystem and harness the power of cutting-edge algorithms. You’ll further explore the mechanics of how “causes leave traces” and compare the main families of causal discovery algorithms. The final chapter gives you a broad outlook into the future of causal AI where we examine challenges and opportunities and provide you with a comprehensive list of resources to learn more. By the end of this book, you will be able to build your own models for causal inference and discovery using statistical and machine learning techniques as well as perform basic project assessment.

Wrapping it up

We started this chapter with a refresher on important causal discovery assumptions. We then introduced gCastle. We discussed the library’s main modules and trained our first causal discovery algorithm. Next, we discussed the four main families of causal discovery models – constraint-based, score-based, functional, and gradient-based – and implemented at least one model per family using gCastle. Finally, we ran a comparative experiment and learned how to pass expert knowledge to causal models.

In the next chapter, we’ll discuss more advanced ideas in causal discovery and take a broader perspective on the applicability of causal discovery methods in real-life use cases.
