tf.multinomial(logits, num_samples, seed=None, name=None)
See the guide: Constants, Sequences, and Random Values > Random Tensors
Draws samples from a multinomial distribution.
Example:
# samples has shape [1, 5], where each value is either 0 or 1 with equal # probability. samples = tf.multinomial(tf.log([[10., 10.]]), 5)
logits
: 2-D Tensor with shape [batch_size, num_classes]
. Each slice [i, :]
represents the unnormalized log probabilities for all classes.num_samples
: 0-D. Number of independent samples to draw for each row slice.seed
: A Python integer. Used to create a random seed for the distribution. See tf.set_random_seed
for behavior.name
: Optional name for the operation.The drawn samples of shape [batch_size, num_samples]
