class_docstr: Random Interval Spectral Ensemble (RISE).
  
  Input: n series length m
  For each tree
      - sample a random intervals
      - take the ACF and PS over this interval, and concatenate features
      - build tree on new features
  Ensemble the trees through averaging probabilities.
  
  Parameters
  ----------
  n_estimators : int, default=200
      The number of trees in the forest.
  min_interval : int, default=16
      The minimum width of an interval.
  acf_lag : int, default=100
      The maximum number of autocorrelation terms to use.
  acf_min_values : int, default=4
      Never use fewer than this number of terms to find a correlation.
  n_jobs : int, default=1
      The number of jobs to run in parallel for both `fit` and `predict`.
      ``-1`` means using all processors.
  random_state : int, RandomState instance or None, default=None
      If int, random_state is the seed used by the random number generator;
      If RandomState instance, random_state is the random number generator;
      If None, the random number generator is the RandomState instance used
      by `np.random`.
  
  Attributes
  ----------
  n_classes_ : int
      The number of classes.
  classes_ : list
      The classes labels.
  intervals_ : array of shape = [n_estimators][2]
      Stores indexes of start and end points for all classifiers.
