NLP - The Visual Way

About this course

“NLP - The Visual Way” is a course dedicated to natural language processing using visual tools in Dataiku DSS. It assumes a basic familiarity with visual machine learning in Dataiku DSS.

In the hands-on lessons, we will work with a dataset of movie reviews. Our task will be to build models to classify reviews as positive or negative.

Before each hands-on section, you will have a chance to grasp each new concept by watching short videos. In the concept videos, we’ll look at a simple example of classifying SMS messages as spam or not-spam.

At the end of this course, you will be able to:

1 - Understand the goals and challenges of Natural Language Processing (NLP)

2 - Prepare a dataset for NLP tasks with transformations like normalization, stopwords removal, and stemming

3 - Apply different strategies for handling text features in machine learning tasks and understand the tradeoffs between them
