+    Given the nature of EEMD, each time you decompose a signal you will obtain a different set of components.
+    That's the expected consequence of adding noise which is going to be random.
+    To make the decomposition reproducible, one needs to set a seed for the random number generator used in EEMD.
+    This is done using :func:`PyEMD.EEMD.noise_seed` method on the instance.
