tf.contrib.distributions.Exponential.__init__(lam, validate_args=False, allow_nan_stats=True, name='Exponential')
Construct Exponential distribution with parameter lam.
Args:
lam: Floating point tensor, the rate of the distribution(s). lam must contain only positive values.
validate_args: Boolean, default False. Whether to assert that lam > 0, and that x > 0 in the methods prob(x) and log_prob(x). If validate_args is False and the inputs are invalid, correct behavior is not guaranteed.
