Class LowerBound<U extends Number>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.LowerBound<U>

Type Parameters:

U - data type for output() output

All Implemented Interfaces:

Op, Operand<U>

public final class LowerBound<U extends Number>
extends PrimitiveOp
implements Operand<U>

Applies lower_bound(sorted_search_values, values) along each row.

Each set of rows with the same index in (sorted_inputs, values) is treated independently. The resulting row is the equivalent of calling `np.searchsorted(sorted_inputs, values, side='left')`.

The result is not a global index to the entire `Tensor`, but rather just the index in the last dimension.

A 2-D example: sorted_sequence = [[0, 3, 9, 9, 10], [1, 2, 3, 4, 5]] values = [[2, 4, 9], [0, 2, 6]]

result = LowerBound(sorted_sequence, values)

result == [[1, 2, 2], [0, 1, 5]]

Method Detail

create

public static <U extends Number,T> LowerBound<U> create(Scope scope,
                                                        Operand<T> sortedInputs,
                                                        Operand<T> values,
                                                        Class<U> outType)

Factory method to create a class to wrap a new LowerBound operation to the graph.

Parameters:

scope - current graph scope

sortedInputs - 2-D Tensor where each row is ordered.

values - 2-D Tensor with the same numbers of rows as `sorted_search_values`. Contains the values that will be searched for in `sorted_search_values`.

outType -

Returns:

a new instance of LowerBound

create

public static <T> LowerBound<Integer> create(Scope scope,
                                             Operand<T> sortedInputs,
                                             Operand<T> values)

Factory method to create a class to wrap a new LowerBound operation to the graph, using default output types.

Parameters:

scope - current graph scope

sortedInputs - 2-D Tensor where each row is ordered.

values - 2-D Tensor with the same numbers of rows as `sorted_search_values`. Contains the values that will be searched for in `sorted_search_values`.

Returns:

a new instance of LowerBound

output

public Output<U> output()

A `Tensor` with the same shape as `values`. It contains the first scalar index into the last dimension where values can be inserted without changing the ordered property.

asOutput

public Output<U> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a 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.

Specified by:

asOutput in interface Operand<U extends Number>
