Finds values and indices of the k
largest elements for the last dimension.
tf.raw_ops.TopKV2(
input,
k,
sorted=True,
index_type=tf.dtypes.int32
,
name=None
)
If the input is a vector (rank-1), finds the k
largest entries in the vector
and outputs their values and indices as vectors. Thus values[j]
is the
j
-th largest entry in input
, and its index is indices[j]
.
For matrices (resp. higher rank input), computes the top k
entries in each
row (resp. vector along the last dimension). Thus,
values.shape = indices.shape = input.shape[:-1] + [k]
If two elements are equal, the lower-index element appears first.
Args | |
---|---|
input
|
A Tensor . Must be one of the following types: float32 , float64 , int32 , uint8 , int16 , int8 , int64 , bfloat16 , uint16 , half , uint32 , uint64 .
1-D or higher with last dimension at least k .
|
k
|
A Tensor . Must be one of the following types: int16 , int32 , int64 .
0-D. Number of top elements to look for along the last dimension (along each
row for matrices).
|
sorted
|
An optional bool . Defaults to True .
If true the resulting k elements will be sorted by the values in
descending order.
|
index_type
|
An optional tf.DType from: tf.int16, tf.int32, tf.int64 . Defaults to tf.int32 .
|
name
|
A name for the operation (optional). |
Returns | |
---|---|
A tuple of Tensor objects (values, indices).
|
|
values
|
A Tensor . Has the same type as input .
|
indices
|
A Tensor of type index_type .
