Memeriksa kualitas data untuk rekomendasi media

Konsol

Untuk memeriksa kualitas data rekomendasi media Anda, ikuti langkah-langkah berikut:

1. Di konsol Google Cloud , buka halaman AI Applications.

   Aplikasi AI

2. Klik nama aplikasi rekomendasi media yang ingin Anda periksa kualitas datanya.

3. Di menu navigasi, klik Kualitas data, lalu klik tab Pengoptimalan. Halaman ini menampilkan status berbagai metrik untuk data yang terkait dengan aplikasi Anda.

4. Tinjau status Kualitas umum dan Kualitas khusus aplikasi di bagian atas halaman. Status ringkasan di bagian atas halaman ditampilkan sebagai peringatan jika satu atau beberapa metrik telah melampaui nilai minimumnya.

   Dua tabel metrik (Kualitas umum dan Kualitas khusus aplikasi) mencantumkan metrik individual.

   

5. Di tabel metrik, klik Lihat detail untuk mengetahui informasi selengkapnya tentang metrik apa pun dalam status peringatan.

6. Opsional: Jika Anda ingin melihat nilai minimum untuk metrik yang mematuhi kebijakan, klik Lihat Detail. Nilai minimum untuk metrik yang mematuhi kebijakan tidak ditampilkan dalam tabel metrik.

REST

Gunakan metode requirements:checkRequirement untuk memeriksa kualitas data rekomendasi media Anda, seperti yang ditunjukkan.

Untuk memeriksa kualitas dari command line, ikuti langkah-langkah berikut:

1. Temukan ID penyimpanan data Anda. Jika Anda sudah memiliki ID penyimpanan data, lanjutkan ke langkah berikutnya.

   1. Di konsol Google Cloud , buka halaman AI Applications dan di menu navigasi, klik Data Stores.

      Buka halaman Data Stores

   2. Klik nama penyimpanan data Anda.

   3. Di halaman Data untuk penyimpanan data Anda, dapatkan ID penyimpanan data.

2. Jalankan perintah curl berikut untuk mengetahui apakah rekomendasi media Anda memenuhi nilai minimum untuk metrik umum:

3. Tinjau output:

   1. Cari nilai result:

      • Jika nilainya SUCCESS, berarti data Anda memenuhi persyaratan umum; lanjutkan ke langkah 4.

      • Jika nilainya WARNING, lanjutkan ke langkah b.

      • Jika Anda tidak melihat result di output, ada beberapa kemungkinan penyebabnya:

        • PROJECT_ID atau DATA_STORE_ID dalam permintaan salah.

        • Beberapa nilai metrik tidak tersedia. Coba lagi dalam 6 jam atau hubungi customer engineer untuk mendapatkan bantuan.

   2. Cari ekspresi (requirement.Condition.Expression): Jika ekspresi ini dievaluasi ke salah (false), berarti ada masalah dengan data Anda.

      Nilai metrik ada di kolom requirementCondition.metricResults.value. Nilai ambang batas peringatan ada di kolom thresholdBindings.thresholdValues. Kolom description dapat membantu Anda memahami tujuan metrik.

      Misalnya, nilai doc_with_same_title_percentage adalah 30.47 dan nilai minimum peringatan untuk doc_with_same_title_percentage_threshold adalah 1. Ada masalah data yang menyebabkan begitu banyak judul di penyimpanan data yang sama, dan hal ini perlu diselidiki.

4. Jika kombinasi model dan tujuan yang digunakan untuk aplikasi rekomendasi Anda muncul dalam tabel ini, Anda juga perlu memanggil metode persyaratan pemeriksaan, yang diperbarui dengan nilai untuk model dan tujuan Anda:

5. Tinjau output:

   1. Cari nilai result:

      • Jika nilainya SUCCESS, berarti data Anda sudah cukup baik.

      • Jika nilainya WARNING, lanjutkan ke langkah b.

      • Jika Anda tidak melihat result di output, ada beberapa kemungkinan penyebabnya:

        • Beberapa nilai metrik tidak tersedia. Coba lagi dalam 6 jam atau hubungi customer engineer untuk mendapatkan bantuan.

   2. Lihat ekspresi (requirement.Condition.Expression). Jika ekspresi ini bernilai salah (false), berarti ada masalah dengan data Anda.

      Nilai metrik dapat ditemukan di kolom requirementCondition.metricResults.value, dan nilai batas peringatan, di kolom thresholdBindings.thresholdValues. Kolom description dapat membantu Anda memahami tujuan metrik.
