Mengelola dan menemukan fitur

Pelajari cara mengelola dan menemukan fitur.

Membuat fitur

Buat satu fitur untuk jenis entity yang ada. Untuk membuat beberapa fitur dalam satu permintaan, lihat Membuat fitur secara massal.

UI Web

  1. Di bagian Vertex AI pada Konsol Google Cloud, buka halaman Features.

    Buka halaman Fitur

  2. Pilih region dari menu drop-down Region.
  3. Dalam tabel fitur, lihat kolom Jenis entity lalu klik jenis entity yang ingin ditambah fitur.
  4. Klik Tambahkan fitur untuk membuka panel Tambahkan fitur.
  5. Tentukan nama, jenis nilai, dan (opsional) deskripsi untuk fitur.
  6. Untuk mengaktifkan pemantauan nilai fitur (Pratinjau), di bagian Pemantauan fitur, pilih Ganti konfigurasi pemantauan jenis entity, lalu masukkan jumlah hari antar-snapshot. Konfigurasi ini akan mengganti konfigurasi pemantauan yang sudah ada atau yang akan datang pada jenis entity fitur tersebut. Untuk mengetahui informasi selengkapnya, lihat Pemantauan nilai fitur.
  7. Untuk menambahkan fitur lainnya, klik Tambahkan fitur lainnya.
  8. Klik Save.

REST

Untuk membuat fitur untuk jenis entity yang sudah ada, kirim permintaan POST menggunakan metode featurestores.entityTypes.features.create.

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

  • LOCATION_ID: Region tempat featurestore berada, seperti us-central1.
  • PROJECT_ID: Project ID Anda.
  • FEATURESTORE_ID: ID featurestore.
  • ENTITY_TYPE_ID: ID jenis entity.
  • FEATURE_ID: ID untuk fitur.
  • DESCRIPTION: Deskripsi fitur.
  • VALUE_TYPE: Jenis nilai fitur.

Metode HTTP dan URL: 

POST https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID?featureId=FEATURE_ID

Isi JSON permintaan: 

{
  "description": "DESCRIPTION",
  "valueType": "VALUE_TYPE"
}

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID?featureId=FEATURE_ID"

PowerShell

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID?featureId=FEATURE_ID" | Select-Object -Expand Content

Anda akan melihat output yang mirip dengan berikut ini: Anda dapat menggunakan OPERATION_ID sebagai respons untuk mendapatkan status operasi.

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.CreateFeatureOperationMetadata",
    "genericMetadata": {
      "createTime": "2021-03-02T00:04:13.039166Z",
      "updateTime": "2021-03-02T00:04:13.039166Z"
    }
  }
}

Fitur pembuatan secara massal

Membuat fitur secara massal untuk jenis yang sudah ada. Untuk permintaan pembuatan batch, Vertex AI Feature Store (Lama) dapat membuat beberapa fitur sekaligus, dan cara ini lebih cepat untuk membuat fitur dalam jumlah besar dibandingkan dengan metode featurestores.entityTypes.features.create.

UI Web

Lihat membuat fitur.

REST

Untuk membuat satu atau beberapa fitur jenis entity yang sudah ada, kirim permintaan POST menggunakan metode featurestores.entityTypes.features.batchCreate seperti yang ditunjukkan dalam contoh berikut.

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

  • LOCATION_ID: Region tempat featurestore berada, seperti us-central1.
  • PROJECT_ID: Project ID Anda.
  • FEATURESTORE_ID: ID featurestore.
  • ENTITY_TYPE_ID: ID jenis entity.
  • PARENT: Nama resource jenis entity tempat membuat fitur. Format yang diperlukan:
    projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID
  • FEATURE_ID: ID untuk fitur.
  • DESCRIPTION: Deskripsi fitur.
  • VALUE_TYPE: Jenis nilai fitur.
  • DURATION: (Opsional) Durasi interval antar-snapshot dalam hitungan detik. Nilai harus diakhiri dengan `s`.

Metode HTTP dan URL: 

POST https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID/features:batchCreate

Isi JSON permintaan: 

{
  "requests": [
    {
      "parent" : "PARENT_1",
      "feature": {
        "description": "DESCRIPTION_1",
        "valueType": "VALUE_TYPE_1",
        "monitoringConfig": {
          "snapshotAnalysis": {
            "monitoringInterval": "DURATION"
          }
        }
      },
      "featureId": "FEATURE_ID_1"
    },
    {
      "parent" : "PARENT_2",
      "feature": {
        "description": "DESCRIPTION_2",
        "valueType": "VALUE_TYPE_2",
        "monitoringConfig": {
          "snapshotAnalysis": {
            "monitoringInterval": "DURATION"
          }
        }
      },
      "featureId": "FEATURE_ID_2"
    }
  ]
}

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID/features:batchCreate"

PowerShell

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://LOCATION_ID-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/entityTypes/ENTITY_TYPE_ID/features:batchCreate" | Select-Object -Expand Content

Anda akan melihat output yang mirip dengan berikut ini: Anda dapat menggunakan OPERATION_ID sebagai respons untuk mendapatkan status operasi.

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION_ID/featurestores/FEATURESTORE_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.BatchCreateFeaturesOperationMetadata",
