Class StringToHashBucketFast

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.StringToHashBucketFast

All Implemented Interfaces:

Op, Operand<Long>

@Operator
public final class StringToHashBucketFast
extends PrimitiveOp
implements Operand<Long>

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the process and will never change. However, it is not suitable for cryptography. This function may be used when CPU time is scarce and inputs are trusted or unimportant. There is a risk of adversaries constructing inputs that all hash to the same bucket. To prevent this problem, use a strong hash function with `tf.string_to_hash_bucket_strong`.

Method Detail

create

public static StringToHashBucketFast create(Scope scope,
                                            Operand<String> input,
                                            Long numBuckets)

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

Parameters:

scope - current graph scope

input - The strings to assign a hash bucket.

numBuckets - The number of buckets.

Returns:

a new instance of StringToHashBucketFast

output

public Output<Long> output()

A Tensor of the same shape as the input `string_tensor`.

asOutput

public Output<Long> 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<Long>
