Visualizing Class Separability - Independent Component Analysis

The Independent component analysis (ICA) was able to separate each of the 5 classes very well. ICA was conducted for all the different loads as well. 

The figures below shows the class separability for our data. The classes are healthy, 1 BRB, 2 BRB, 3 BRB, 4 BRB.

Each figure displays a different set of load. These include:

  • 5Nm
  • 10Nm
  • 20Nm
  • 30Nm
  • 40Nm
