Machine Learning with Weka

Machine Learning Using Weka

Aim of Course:

Weka is a powerful, open-source machine learning tool. Its users can import data and train many available algorithms to build classification or regression models. This class is a hands-on tutorial that will teach students how to use the Weka platform. We will cover the basics of machine learning including how to choose the right algorithms for your data, and then learn how to format data and import it into Weka, how to build models, and how to analyze and interpret the results.  

In this course, the focus is on learning the Weka tool, in contrast to other courses where the focus is on a more detailed study of the data mining methods.

Anticipated learning outcomes - you will be able to:

  • Navigate Weka, read in data and work with appropriate data formats
  • Use Weka to implement basic data mining algorithms
    • Trees
    • Rule Systems
    • Bayesian Networks
    • Neural Networks
  • Apply appropriate algorithms to classification and regression
  • Assess model results with appropriate metrics
  • Use Weka to classify documents

 

 

This course may be taken individually (one-off) or as part of a certificate program.
