Create confusion matrices and compute metrics with Python

BeginnerGuided Project

Confusion matrices are a common and useful technique for classification tasks. They provide a perspective on the accuracy and effectiveness of algorithms. In this project, work with confusion matrices and classification accuracy as we analyze the effectiveness of spam detection. Uncover valuable insights into sensitivity, specificity, accuracy, and precision. Join us on a journey of discovery through the matrix of classification metrics for some effective spam detection.

About this Guided Project
In this project, you get to explore different metrics that can be from a confusion matrix, a fundamental tool in evaluating the performance of classification models. Learn how to derive different metrics such as accuracy, specificity, sensitivity, and precision with a practical problem - spam detection. Learn different ways to visualize confusion matrices and engage in exercises to build skills that are needed in classification problems. Join us on this journey to enhance your understanding of classification metrics and strengthen your ability to combat spam effectively.

This hands-on project is based on the Create a confusion matrix with Python tutorial. The guided project format combines the instructions of the tutorial with the environment to execute these instructions without the need to download, install, and configure tools.

A look at the project ahead

Tell your audience what they can expect to learn. Better yet, tell them what they will be able to do as a result of completing your project:
  • Use Python to create confusion matrices
  • Learn to derive different measures from a confusion matrix mathematically
  • Derive measured from a confusion matrix with sklearn

What you'll need

  • No installation required: Everything is available in the JupyterLab, including any Python libraries and data sets.
  • Basic understanding of Python: Some basic understanding of Python will be beneficial.
  • Some understanding of statistical concepts: It's helpful to have some understanding of statistic concepts, particularly terms like accuracy, specificity, and precision.
