# tensorflow::ops::DenseBincount Class Reference

# tensorflow::ops::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.

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- input: 1D or 2D int `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor`.
- size: non-negative int scalar `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor`.
- weights: is an int32, int64, float32, or float64 `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` with the same shape as `arr`, or a length-0 `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor`, in which case it acts as all weights equal to 1.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r2.3/api_docs/cc/struct/tensorflow/ops/dense-bincount/attrs#structtensorflow_1_1ops_1_1_dense_bincount_1_1_attrs`):

- binary_output: bool; Whether the kernel should count the appearance or number of occurrences.

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: 1D `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` with length equal to `size` or 2D `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` with \[batch_size, `size`\]. The counts or summed weights for each value in the range \[0, size).
