Computes the percentage of values less than the given threshold.
tf.contrib.metrics.streaming_percentage_less(
values, threshold, weights=None, metrics_collections=None,
updates_collections=None, name=None
)
The streaming_percentage_less
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
|
An optional Tensor whose shape is broadcastable to values .
|
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.
