Machine Learning with MATLAB: Getting Started with Classification

Richard Willey, MathWorks

Classification is used to assign items to a discrete group or class based on a specific set of features. Classification algorithms are a core component of statistical learning / machine learning.

In this webinar we introduce the classification capabilities included in Statistics and Machine Learning Toolbox.

Representative examples include:

  • Identifying vehicle type based on an acoustic signal or an image
  • Sorting manufactured goods using images (optical quality control)
  • Assigning a credit rating using information included in a financial statement
  • Predicting a tumor type based on a DNA profile
  • Filtering SPAM using the frequency of different words in an email

Applied examples using real world data sets are used to describe how you can:

  • Choose between classification algorithms (bagged decision trees, naïve Bayes classifiers, discriminant analysis, and logistic regression)
  • Train your classifier
  • Evaluate the accuracy of a classifier (confusion matrices, ROC curves, classification error)
  • Simplify your classification model
