title: How to implement a Common spectral pattern (CSP) in the real-time application?
body: <p>I am trying to implement &quot;Common Spatial Pattern (CSP)&quot; as a feature extraction method.
  But most of the implementation of CSP that available is in binary or multiclass (input: minimum requirement two-class). So, If I want to use it in a real-time application, how can I implement this? (At that time, we will put a single observation for the testing purpose that contain a single class).
  I will be grateful if anyone help to understand the logic of CSP in the real-time application.</p>
