tf.math.zero_fraction

View source on GitHub

Returns the fraction of zeros in value.

Aliases:

• tf.compat.v1.math.zero_fraction
• tf.compat.v1.nn.zero_fraction
• tf.compat.v2.math.zero_fraction
• tf.compat.v2.nn.zero_fraction
• tf.nn.zero_fraction

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

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.compat.v1.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.
