aliran tensor:: operasi:: StringToHashBucketFast
#include <string_ops.h> Mengonversi setiap string di Tensor masukan menjadi mod hashnya sebanyak beberapa keranjang.
Ringkasan
Fungsi hash bersifat deterministik pada konten string dalam proses dan tidak akan pernah berubah. Namun, ini tidak cocok untuk kriptografi. Fungsi ini dapat digunakan ketika waktu CPU terbatas dan input dipercaya atau tidak penting. Ada risiko musuh menyusun masukan yang semuanya di-hash ke keranjang yang sama. Untuk mencegah masalah ini, gunakan fungsi hash yang kuat dengan tf.string_to_hash_bucket_strong .
Contoh:
tf.strings.to_hash_bucket_fast(["Halo", "TensorFlow", "2.x"], 3).numpy() array([0, 2, 2])
Argumen:
- ruang lingkup: Objek Lingkup
- input: String untuk menetapkan keranjang hash.
- num_buckets: Jumlah keranjang.
Pengembalian:
-
Output : Tensor dengan bentuk yang sama dengan input string_tensor .

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`.\n\nExamples:\n\ntf.strings.to_hash_bucket_fast(\\[\"Hello\", \"TensorFlow\", \"2.x\"\\], 3).numpy() array(\\[0, 2, 2\\])\n\nArguments:\n\n- scope: A [Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- input: The strings to assign a hash bucket.\n- num_buckets: The number of buckets.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): A [Tensor](/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) of the same shape as the input `string_tensor`.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n| [StringToHashBucketFast](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1aeb05e5b10fdc6f834f05a653d410f7f7)`(const ::`[tensorflow::Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.3/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` input, int64 num_buckets)` ||\n\n| ### Public attributes ||\n|--------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|\n| [operation](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1a0952b49db809f413e63d82b3f012df4f) | [Operation](/versions/r2.3/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation) |\n| [output](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1a18fa68753ab137a6da6fdd02e1eca30f) | `::`[tensorflow::Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) |\n\n| ### Public functions ||\n|--------------------------------------------------------------------------------------------------------------------------------------|------------------------|\n| [node](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1ae3368d6c128d5c8bd06c2ba972391f6e)`() const ` | `::tensorflow::Node *` |\n| [operator::tensorflow::Input](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1adc1ece493cd1b706ea7d316631c56148)`() const ` | ` ` ` ` |\n| [operator::tensorflow::Output](#classtensorflow_1_1ops_1_1_string_to_hash_bucket_fast_1a0a330a80b9f8aa32ee15556dd3e68aa4)`() const ` | ` ` ` ` |\n\nPublic attributes\n-----------------\n\n### operation\n\n```text\nOperation operation\n``` \n\n### output\n\n```text\n::tensorflow::Output output\n``` \n\nPublic functions\n----------------\n\n### StringToHashBucketFast\n\n```gdscript\n StringToHashBucketFast(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input input,\n int64 num_buckets\n)\n``` \n\n### node\n\n```gdscript\n::tensorflow::Node * node() const \n``` \n\n### operator::tensorflow::Input\n\n```gdscript\n operator::tensorflow::Input() const \n``` \n\n### operator::tensorflow::Output\n\n```gdscript\n operator::tensorflow::Output() const \n```"]]
