aliran tensor:: operasi:: SparseCross
#include <sparse_ops.h> Menghasilkan persilangan renggang dari daftar tensor renggang dan padat.
Ringkasan
Operasi ini mengambil dua daftar, satu dari 2D SparseTensor dan satu dari 2D Tensor , masing-masing mewakili fitur dari satu kolom fitur. Ini menghasilkan SparseTensor 2D dengan persilangan fitur-fitur ini secara batch.
Misalnya, jika masukannya adalah
inputs[0]: SparseTensor with shape = [2, 2]
[0, 0]: "a"
[1, 0]: "b"
[1, 1]: "c"
inputs[1]: SparseTensor with shape = [2, 1]
[0, 0]: "d"
[1, 0]: "e"
inputs[2]: Tensor [["f"], ["g"]]
maka outputnya adalah
shape = [2, 2]
[0, 0]: "a_X_d_X_f"
[1, 0]: "b_X_e_X_g"
[1, 1]: "c_X_e_X_g"
jika hashed_output=true maka outputnya akan menjadi
shape = [2, 2]
[0, 0]: FingerprintCat64(
Fingerprint64("f"), FingerprintCat64(
Fingerprint64("d"), Fingerprint64("a")))
[1, 0]: FingerprintCat64(
Fingerprint64("g"), FingerprintCat64(
Fingerprint64("e"), Fingerprint64("b")))
[1, 1]: FingerprintCat64(
Fingerprint64("g"), FingerprintCat64(
Fingerprint64("e"), Fingerprint64("c"))) Argumen:
- ruang lingkup: Objek Lingkup
- indeks: 2-D. Indeks setiap masukan
SparseTensor . - nilai: 1-D. nilai setiap
SparseTensor . - bentuk: 1-D. Bentuk setiap
SparseTensor . - input_padat: 2-D. Kolom diwakili oleh
Tensor yang padat. - hashed_output: Jika benar, mengembalikan hash tanda silang, bukan string. Ini akan memungkinkan kita menghindari manipulasi string.
- num_buckets: Digunakan jika hashed_output benar. output = hashed_valuenum_buckets jika num_buckets > 0 jika tidak hash_value.
- hash_key: Tentukan hash_key yang akan digunakan oleh fungsi
FingerprintCat64 untuk menggabungkan sidik jari silang.
Pengembalian:
-
Output keluaran_indeks: 2-D. Indeks dari gabungan SparseTensor . - Nilai keluaran
Output : 1-D. Nilai tidak kosong dari SparseTensor yang digabungkan atau di-hash. - Bentuk keluaran
Output : 1-D. Bentuk SparseTensor yang digabungkan.

It outputs a 2D `SparseTensor` with the batchwise crosses of these features.\n\nFor example, if the inputs are \n\n```text\ninputs[0]: SparseTensor with shape = [2, 2]\n[0, 0]: \"a\"\n[1, 0]: \"b\"\n[1, 1]: \"c\"\n\ninputs[1]: SparseTensor with shape = [2, 1]\n[0, 0]: \"d\"\n[1, 0]: \"e\"\n\ninputs[2]: Tensor [[\"f\"], [\"g\"]]\n```\n\n\u003cbr /\u003e\n\nthen the output will be \n\n```scdoc\nshape = [2, 2]\n[0, 0]: \"a_X_d_X_f\"\n[1, 0]: \"b_X_e_X_g\"\n[1, 1]: \"c_X_e_X_g\"\n```\n\n\u003cbr /\u003e\n\nif hashed_output=true then the output will be \n\n```text\nshape = [2, 2]\n[0, 0]: FingerprintCat64(\n Fingerprint64(\"f\"), FingerprintCat64(\n Fingerprint64(\"d\"), Fingerprint64(\"a\")))\n[1, 0]: FingerprintCat64(\n Fingerprint64(\"g\"), FingerprintCat64(\n Fingerprint64(\"e\"), Fingerprint64(\"b\")))\n[1, 1]: FingerprintCat64(\n Fingerprint64(\"g\"), FingerprintCat64(\n Fingerprint64(\"e\"), Fingerprint64(\"c\")))\n```\n\n\u003cbr /\u003e\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- indices: 2-D.

Columns represented by dense [Tensor](/versions/r2.1/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor).\n- hashed_output: If true, returns the hash of the cross instead of the string. This will allow us avoiding string manipulations.\n- num_buckets: It is used if hashed_output is true. output = hashed_valuenum_buckets if num_buckets \\\u003e 0 else hashed_value.\n- hash_key: Specify the hash_key that will be used by the `FingerprintCat64` function to combine the crosses fingerprints.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) output_indices: 2-D.
