text: Title: Cao Initialisation for k-Prototype
  Body: Hi, 
  
  I've got a question regarding the Cao initialisation procedure. 
  I understand that for categorical data, the centroids are computed deterministically. In k-modes, the number of initialisations is hence set to 1.
  But when using k-prototype, the numerical aspects of the centroids are drawn from a normal distribution. Nonetheless, the number of initialisations is set to 1. Is there a way to do multiple initialisations for this case?
  
  Thanks!
  
  Best regards
