tf.compat.v1.metrics.percentage_below

tf.metrics.percentage_below(
    values, threshold, weights=None, metrics_collections=None,
    updates_collections=None, name=None
)

The percentage_below function creates two local variables, total and count that are used to compute the percentage of values that fall below threshold. This rate is weighted by weights, and it is ultimately returned as percentage which is an idempotent operation that simply divides total by count.

For estimation of the metric over a stream of data, the function creates an update_op operation that updates these variables and returns the percentage.

If weights is None, weights default to 1. Use weights of 0 to mask values.

Args
values	A numeric Tensor of arbitrary size.
threshold	A scalar threshold.
weights	Optional Tensor whose rank is either 0, or the same rank as values, and must be broadcastable to values (i.e., all dimensions must be either 1, or the same as the corresponding values dimension).
metrics_collections	An optional list of collections that the metric value variable should be added to.
updates_collections	An optional list of collections that the metric update ops should be added to.
name	An optional variable_scope name.

Returns
percentage	A Tensor representing the current mean, the value of total divided by count.
update_op	An operation that increments the total and count variables appropriately.

Raises
ValueError	If weights is not None and its shape doesn't match values, or if either metrics_collections or updates_collections are not a list or tuple.
RuntimeError	If eager execution is enabled.
