class_docstr: Encoder specifically for the EIPS (expected improvement per second) acquisition function.
docstr: Transform function response values. Transform the runtimes by a log transformation
  log(1. + runtime).
  
  Parameters
  ----------
  values : np.ndarray
      Response values to be transformed.
  
  Returns
  -------
  np.ndarray
