Reproducible Data Science with Pachyderm

By: Svetlana Karslioglu

Overview of this book

Pachyderm is an open source project that enables data scientists to run reproducible data pipelines and scale them to an enterprise level. This book will teach you how to implement Pachyderm to create collaborative data science workflows and reproduce your ML experiments at scale. You’ll begin your journey by exploring the importance of data reproducibility and comparing different data science platforms. Next, you’ll explore how Pachyderm fits into the picture and its significance, followed by learning how to install Pachyderm locally on your computer or a cloud platform of your choice. You’ll then discover the architectural components and Pachyderm's main pipeline principles and concepts. The book demonstrates how to use Pachyderm components to create your first data pipeline and advances to cover common operations involving data, such as uploading data to and from Pachyderm to create more complex pipelines. Based on what you've learned, you'll develop an end-to-end ML workflow, before trying out the hyperparameter tuning technique and the different supported Pachyderm language clients. Finally, you’ll learn how to use a SaaS version of Pachyderm with Pachyderm Notebooks. By the end of this book, you will learn all aspects of running your data pipelines in Pachyderm and manage them on a day-to-day basis.

Creating an NER pipeline

NER is an information extraction technique that recognizes entities in text and puts them in certain categories, such as person, location, and organization. For example, say we have the following phrase:

Snap Inc. Announces First Quarter 2021 Financial Results

If you use spaCy's en_core_web_lg against this phrase, you will get the following results:

Snap Inc. - 0 - 9 - ORG - Companies, agencies, institutions, etc.
First Quarter 2021 - 20 - 38 - DATE - Absolute or relative dates or periods

Name recognition can be useful in a variety of tasks. In this section, we will use it to retrieve the main characters of The Legend of Sleepy Hollow.

Here is what our NER pipeline specification will look like:

---
 pipeline:
   name: ner

   pfs:
     glob: "/text.txt"
