tf.contrib.distributions.Dirichlet.mode(name='mode')

Mode.

Additional documentation from Dirichlet:

Note that the mode for the Dirichlet distribution is only defined when alpha > 1. This returns the mode when alpha > 1, and NaN otherwise. If self.allow_nan_stats is False, an exception will be raised rather than returning NaN.
