Look inside

In this liveProject, you’ll use the neural network-inspired Contextual Topic Model to identify and visualize all of the articles in a scientific magazine’s back catalog. This cutting-edge technique is made easy by the OCTIS (Optimizing and Comparing Topic Models is Simple!) library. Once you’ve established your text-processing pipeline, you’ll use coherence and diversity metrics to evaluate the output of your topic models, tune your neural network’s hyperparameters to improve results, and visualize your results for printing on posters and other media.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

prerequisites

This liveProject is for data scientists and developers who are confident programming with Python and the Python data ecosystem. To begin this liveProject you will need to be familiar with the following:


TOOLS
  • Intermediate Python
  • Basics of Jupyter Notebook
TECHNIQUES
  • Linear algebra
  • Basics of deep learning

you will learn

In this liveProject, you’ll master topic modeling—an amazing skill for quickly analyzing textual datasets. You’ll learn to apply the cutting-edge neural topic model in a real-world setting:


  • Exploring the vector representations produced by the Bidirectional Encoder Representations from Transformers (BERT) neural network and their use in the Contextual Topic Model (CTM)
  • Using the Contextual Topic Model and comparing to the output of Latent Dirichlet Allocation
  • Preprocess text documents
  • Using Topic Coherence and Diversity metrics
  • Visualizing derived topics with a variety of techniques
