tf.nn.zero_fraction

tf.nn.zero_fraction(
    value,
    name=None
)

Defined in tensorflow/python/ops/nn_impl.py.

Returns the fraction of zeros in value.

If value is empty, the result is nan.

This is useful in summaries to measure and report sparsity. For example,

    z = tf.nn.relu(...)
    summ = tf.summary.scalar('sparsity', tf.nn.zero_fraction(z))

Args:

  • value: A tensor of numeric type.
  • name: A name for the operation (optional).

Returns:

The fraction of zeros in value, with type float32.
