tf.strings.to_hash_bucket_fast
Stay organized with collections Save and categorize content based on your preferences.
Converts each string in the input Tensor to its hash mod by a number of buckets.
tf.strings.to_hash_bucket_fast(
input: Annotated[Any, _atypes.String], num_buckets: int, name=None
) -> Annotated[Any, _atypes.Int64]
Used in the notebooks
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.
Examples:
tf.strings.to_hash_bucket_fast(["Hello", "TensorFlow", "2.x"], 3).numpy()
array([0, 2, 2])
Args |
|---|
input | A Tensor of type string. The strings to assign a hash bucket. |
num_buckets | An int that is >= 1. The number of buckets. |
