Classification of data generated by radar using FFT I have time domain data which is having binary label in form of 0 and 1. I applied FFT to all the features and label as well. The problem is my output label is now not binary anymore. How to solve this classification problem?
If you are dealing with a classification problem, you should treat the $0$ and $1$ as labels. 

The goal of FFT is to convert time domain to frequency domain. 

You do not want to include the label as part of your FFT procedure.
