Type SparseFeatureColumn

Namespace tensorflow.contrib.linear_optimizer

Parent PythonObjectContainer

Interfaces ISparseFeatureColumn

Represents a sparse feature column.

Contains three tensors representing a sparse feature column, they are example indices (`int64`), feature indices (`int64`), and feature values (`float`). Feature weights are optional, and are treated as `1.0f` if missing.

For example, consider a batch of 4 examples, which contains the following features in a particular `SparseFeatureColumn`:

* Example 0: feature 5, value 1 * Example 1: feature 6, value 1 and feature 10, value 0.5 * Example 2: no features * Example 3: two copies of feature 2, value 1

This SparseFeatureColumn will be represented as follows:

``` <0, 5, 1> <1, 6, 1> <1, 10, 0.5> <3, 2, 1> <3, 2, 1> ```

For a batch of 2 examples below:

* Example 0: feature 5 * Example 1: feature 6

is represented by `SparseFeatureColumn` as:

``` <0, 5, 1> <1, 6, 1>

```
