Membuat dan mengelola model

Anda membuat model kustom dengan melatihnya menggunakan set data yang telah disiapkan. Set data AutoML Translation menggunakan item dari set data untuk melatih model, mengujinya, dan evaluate performanya. Anda akan meninjau hasilnya, menyesuaikan set data pelatihan sesuai kebutuhan, dan melatih model baru menggunakan set data yang ditingkatkan.

Melatih model dapat memerlukan waktu beberapa jam untuk diselesaikan. AutoML API memungkinkan Anda untuk memeriksa status pelatihan.

Karena AutoML Translation membuat model baru setiap kali Anda memulai pelatihan, project Anda mungkin akan mencakup banyak model. Anda bisa mendapatkan daftar model dalam project dan dapat menghapus model yang tidak lagi Anda perlukan.

Melatih model

Jika memiliki set data dengan kumpulan pasangan kalimat pelatihan yang solid, Anda siap untuk membuat dan melatih model kustom.

UI web

Buka UI AutoML Translation.

Halaman Set data menampilkan set data yang tersedia untuk project saat ini.
Pilih set data yang ingin Anda gunakan untuk melatih model kustom.

Nama tampilan set data yang dipilih akan muncul di batang judul, dan halaman mencantumkan setiap item dalam set data bersama dengan label "Pelatihan", "Validasi", atau "Pengujian" masing-masing.
Setelah selesai meninjau set data, klik tab Latih tepat di bawah batang judul.
Klik Mulai Pelatihan.

Kotak dialog Latih model baru akan muncul.
Tentukan nama untuk model.
Klik Mulai Pelatihan untuk mulai melatih model kustom Anda.

Proses pelatihan model dapat memakan waktu beberapa jam untuk diselesaikan. Setelah model berhasil dilatih, Anda akan menerima pesan di alamat email yang Anda gunakan untuk mendaftar ke program.

REST

Sebelum menggunakan data permintaan apa pun, ganti nilai berikut ini:

project-id: project ID Google Cloud Platform Anda
model-name: nama model baru Anda
dataset-id: ID set data Anda. ID adalah elemen terakhir dari nama set data Anda. Misalnya, jika nama set data Anda adalah projects/434039606874/locations/us-central1/datasets/3104518874390609379, maka ID set data Anda adalah 3104518874390609379.

Metode HTTP dan URL:

POST https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models

Isi JSON permintaan:

Mendapatkan status operasi

Anda dapat memeriksa status tugas yang berjalan lama (mengimpor item ke set data atau melatih model) menggunakan ID operasi dari respons saat memulai tugas.

Anda hanya dapat memeriksa status operasi menggunakan AutoML API.

Untuk mendapatkan status operasi pelatihan, Anda harus mengirim permintaan GET ke resource operations. Berikut ini cara mengirim permintaan tersebut.

Sebelum menggunakan data permintaan apa pun, ganti nilai berikut ini:

operation-name: nama operasi seperti yang ditampilkan dalam respons terhadap panggilan asli ke API
project-id: project ID Google Cloud Platform Anda

Metode HTTP dan URL:

GET https://automl.googleapis.com/v1/operation-name

Untuk mengirim permintaan, luaskan salah satu opsi berikut:

curl (Linux, macOS, atau Cloud Shell)

Jalankan perintah berikut:

curl -X GET \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "x-goog-user-project: project-id" \
    "https://automl.googleapis.com/v1/operation-name"

PowerShell (Windows)

Jalankan perintah berikut:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://automl.googleapis.com/v1/operation-name" | Select-Object -Expand Content

Anda akan melihat respons JSON yang mirip dengan berikut ini:

{
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1.OperationMetadata",
    "createTime": "2019-10-01T22:13:48.155710Z",
    "updateTime": "2019-10-01T22:13:52.321072Z",
    ...
  },
  "done": true,
  "response": {
    "@type": "resource-type",
    "name": "resource-name"
  }
}

Membatalkan Operasi

Anda dapat membatalkan tugas impor atau pelatihan menggunakan ID operasi.

Sebelum menggunakan data permintaan apa pun, ganti nilai berikut ini:

operation-name: nama lengkap operasi. Nama lengkap menggunakan format projects/project-id/locations/us-central1/operations/operation-id.
project-id: project ID Google Cloud Platform Anda

Metode HTTP dan URL:

POST https://automl.googleapis.com/v1/operation-name:cancel

Untuk mengirim permintaan, luaskan salah satu opsi berikut:

curl (Linux, macOS, atau Cloud Shell)

Jalankan perintah berikut:

curl -X POST \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "x-goog-user-project: project-id" \
    -H "Content-Type: application/json; charset=utf-8" \
    -d "" \
    "https://automl.googleapis.com/v1/operation-name:cancel"

PowerShell (Windows)

Jalankan perintah berikut:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `

Menghapus model

Contoh berikut akan menghapus model.

UI web

Di UI AutoML Translation, klik ikon bola lampu di menu navigasi kiri untuk menampilkan daftar model yang tersedia.
Klik menu tiga titik di ujung kanan baris yang ingin Anda hapus, lalu pilih Hapus model.
Klik Hapus di kotak dialog konfirmasi.

REST

Sebelum menggunakan data permintaan apa pun, ganti nilai berikut ini:

model-name: nama lengkap model Anda. Nama lengkap model mencakup nama dan lokasi project Anda. Nama model mirip dengan contoh berikut: projects/project-id/locations/us-central1/models/model-id.
project-id: project ID Google Cloud Platform Anda

Metode HTTP dan URL:

DELETE https://automl.googleapis.com/v1/model-name

Untuk mengirim permintaan, luaskan salah satu opsi berikut:

curl (Linux, macOS, atau Cloud Shell)

Jalankan perintah berikut:

curl -X DELETE \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "x-goog-user-project: project-id" \
    "https://automl.googleapis.com/v1/model-name"

PowerShell (Windows)

Jalankan perintah berikut:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://automl.googleapis.com/v1/model-name" | Select-Object -Expand Content

Anda akan melihat respons JSON yang mirip dengan berikut ini:

{
  "name": "projects/project-number/locations/us-central1/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1beta1.OperationMetadata",
    "progressPercentage": 100,
    "createTime": "2018-04-27T02:33:02.479200Z",
