DenseBincount
#include <math_ops.h>
Counts the number of occurrences of each value in an integer array.
Summary
Outputs a vector with length
size
and the same dtype as
weights
. If
weights
are empty, then index
i
stores the number of times the value
i
is counted in
arr
. If
weights
are non-empty, then index
i
stores the sum of the value in
weights
at each index where the corresponding value in
arr
is
i
.
Values in
arr
outside of the range [0, size) are ignored.
Args:
-
scope: A
Scope
object
-
input: 1D or 2D int
Tensor
.
-
size: non-negative int scalar
Tensor
.
-
weights: is an int32, int64, float32, or float64
Tensor
with the same shape as
arr
, or a length-0
Tensor
, in which case it acts as all weights equal to 1.
Optional attributes (see
Attrs
):
-
binary_output: bool; Whether the kernel should count the appearance or number of occurrences.
Returns:
-
Output
: 1D
Tensor
with length equal to
size
or 2D
Tensor
with [batch_size,
size
]. The counts or summed weights for each value in the range [0, size).
