SegmentProd

public final class SegmentProd

Computes the product along segments of a tensor.

Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.

Computes a tensor such that \\(output_i = \prod_j data_j\\) where the product is over `j` such that `segment_ids[j] == i`.

If the product is empty for a given segment ID `i`, `output[i] = 1`.

For example:

c = tf.constant([[1,2,3,4], [4, 3, 2, 1], [5,6,7,8]])
 tf.segment_prod(c, tf.constant([0, 0, 1]))
 # ==> [[4, 6, 6, 4],
 #      [5, 6, 7, 8]]
 

Constants

Returns the symbolic handle of the tensor.
static <T extends TType > SegmentProd <T>
create ( Scope scope, Operand <T> data, Operand <? extends TNumber > segmentIds)
Factory method to create a class wrapping a new SegmentProd operation.
Output <T>

Inherited Methods

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "SegmentProd"

Public Methods

public Output <T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static SegmentProd <T> create ( Scope scope, Operand <T> data, Operand <? extends TNumber > segmentIds)

Factory method to create a class wrapping a new SegmentProd operation.

Parameters
scope current scope
segmentIds A 1-D tensor whose size is equal to the size of `data`'s first dimension. Values should be sorted and can be repeated.
Returns
  • a new instance of SegmentProd

public Output <T> output ()

Has same shape as data, except for dimension 0 which has size `k`, the number of segments.
