Machine Learning with Text in Python

Is this Data School course right for you?

Are you trying to master machine learning in Python, but tired of wasting your time on courses that don't move you towards your goal? Do you recognize the enormous value of text-based data, but don't know how to apply the right machine learning and Natural Language Processing techniques to extract that value?

In this Data School course, you'll gain hands-on experience using machine learning and Natural Language Processing to solve text-based data science problems. By the end of the course, you'll be able to confidently apply these techniques to your own data science problems.

Ryan Cranfill (Product Data Analyst): "The course was a perfect introduction to machine learning with text, and I was able to apply topics covered during the first week to my work. Kevin does a great job of breaking down complex topics and providing a practical, real-world context for them."

How is this course different from other online courses?

Most data science courses suffer from a host of problems: They're poorly taught, lack the necessary depth, and include unexplained or broken code. They don't teach you how to apply what you're learning, and when you do apply it, there's no way to know how well you're doing.

But in this course, we'll go deep into machine learning with text, focusing on application from day one. We'll spend most of our time writing Python code, and you'll understand how every single line relates to the problem we're solving. You'll practice what you're learning through carefully crafted lessons and assignments.

At the end of this course, you'll leave with valuable machine learning experience, high-quality code that you can reuse to solve future text-based problems, a student community you can continue to turn to with questions, and a wealth of curated resources to help you deepen your understanding of each course topic.

Harvey Summers (Information Security Team Leader): "Kevin Markham's Data School courses are remarkably good. Kevin has the ability to simplify complicated concepts and explain not only how to code, but also the 'why' behind it. I have been very happy with the cost and quality of the courses and have learned more in 4 weeks than the 18 months of coursework I've taken from a leading university."

Course Outline

Each module includes 2 to 4 hours of instructional videos, 1 lesson notebook, 1 to 2 homework assignments, and 15 to 20 supplementary resources.

Module 1: Working with Text Data in scikit-learn

By the end of this module, you'll be able to confidently perform the basic workflow for machine learning with text: creating a dataset, extracting features from unstructured text, building and evaluating models, and inspecting models for further insight. You'll also gain an understanding of Unicode, enabling you to troubleshoot encoding-based errors.

Module 2: Applying Natural Language Processing Techniques to Machine Learning

By the end of this module, you'll be able to apply a handful of Natural Language Processing techniques to machine learning problems in order to improve the effectiveness of your models. You'll also learn how to perform sentiment analysis and build a simple document summarization tool for your own corpus of text.

Module 3: Parsing Text Data Using Regular Expressions

By the end of this module, you'll be able to extract text features from messy data sources using regular expressions. You'll learn the basic rules and syntax that can be applied across programming languages, and you'll master the most important Python functions and options for working with regular expressions.

Module 4: Workflow for a Text-Based Data Science Problem

By the end of this module, you'll be able to create an end-to-end workflow for solving a text-based data science problem using scikit-learn and pandas. You'll gain experience with data exploration, feature engineering, proper model evaluation, model tuning, and generating predictions for new observations.

Module 5: Advanced Machine Learning Techniques

By the end of this module, you'll be able to apply advanced machine learning techniques to improve the accuracy of your models and the efficiency of your workflow. You'll learn how to build and tune a multi-step, multi-layer machine learning pipeline, as well as how to ensemble and stack your models.

Is this a beginner course?

No. This is an intermediate course, with specific prerequisites:

How do I know whether I'm ready for the course?

Review the content from my scikit-learn video series and my pandas video series. If you are comfortable with most of the content, you are ready for the course. If you are unsure whether you meet the course requirements, please email me!

What types of people have taken this course?

Here are the job titles of some of my past students:

Diane (Full Stack Developer): "The course is amazing! Very logical, and goes quite a bit in depth. The structure is great, as it moves from easy to hard, and in the end, you realize how much you have learned. I highly recommend it to anyone interested in machine learning."

Why should I learn how to work with text?

Most knowledge created by humans is raw, unstructured text. By learning how to transform text into data that is usable by machine learning models, you drastically increase the amount of data that your models can learn from.

NLP overview

What will I be able to do by the end of this course?

Charles Franzen (Assistant Education Manager): "Kevin's courses are focused and coherent. Tools learned each week build upon and complement one another, and the classes culminate with a larger-scale project that shows how what you've learned can come together. I learned a great deal, and highly recommend Data School to those looking to explore machine learning tools in greater depth."

Which version of Python do I need for the course?

Both Python 2 and Python 3 are perfectly acceptable.

What libraries will we be using?

The majority of the content will use scikit-learn, though we will also use pandas to help us load, prepare, and visualize data. We will use the built-in re module for regular expressions. We will also make limited use of NumPy, SciPy, Matplotlib, Seaborn, and TextBlob.

Is the course material up-to-date?

I've spent hundreds of hours building and refining this course with the feedback of my students, and continue to update the course as needed. All of the code is up-to-date with the most widely used version of every library, and is tested in both Python 2 and 3.

Chandler McCann (Manager of Data Analytics): "Kevin is an extremely knowledgeable teacher who cares about his students and puts a ton of preparation into his courses and materials. Kevin's approach to teaching data science is logical, well-structured and accessible. I highly recommend this course."

How is this course different from other online courses?

Dr. Kathleen Perez-Lopez (Senior Data Scientist): "In Machine Learning with Text, Kevin Markham does a superb job walking you through this topic at an intermediate level.
