Exemple d'indicateurs d'équité FaceSSD Colab

Aperçu

Dans cette activité, vous utiliserez des indicateurs d'équité pour explorer les prédictions FaceSSD sur les faces étiquetées dans l'ensemble de données Wild . Les indicateurs d'équité sont une suite d'outils basés sur l'analyse du modèle TensorFlow qui permettent une évaluation régulière des mesures d'équité dans les pipelines de produits.

À propos de l'ensemble de données

Dans cet exercice, vous allez travailler avec l'ensemble de données de prédiction FaceSSD, environ 200 000 prédictions d'image différentes et vérités fondamentales générées par l'API FaceSSD.

À propos des outils

TensorFlow Model Analysis est une bibliothèque permettant d'évaluer les modèles d'apprentissage automatique TensorFlow et non TensorFlow. Il permet aux utilisateurs d'évaluer leurs modèles sur de grandes quantités de données de manière distribuée, de calculer dans le graphique et d'autres mesures sur différentes tranches de données et de les visualiser dans des cahiers.

TensorFlow Data Validation est un outil que vous pouvez utiliser pour analyser vos données. Vous pouvez l'utiliser pour rechercher des problèmes potentiels dans vos données, tels que des valeurs manquantes et des déséquilibres de données, qui peuvent entraîner des disparités d'équité.

Grâce aux indicateurs d'équité , les utilisateurs pourront:

  • Évaluer les performances du modèle, réparties entre des groupes d'utilisateurs définis
  • Ayez confiance en vos résultats avec des intervalles de confiance et des évaluations à plusieurs seuils

Importation

Exécutez le code suivant pour installer la bibliothèque fairness_indicators. Ce package contient les outils que nous utiliserons dans cet exercice. Le redémarrage du Runtime peut être demandé mais n'est pas nécessaire.

pip install -q fairness-indicators

Téléchargez et comprenez les données

Labeled Faces in the Wild est un ensemble de données de référence public pour la vérification des visages, également appelé appariement de paires. LFW contient plus de 13 000 images de visages collectées sur le Web.

Nous avons exécuté des prédictions FaceSSD sur cet ensemble de données pour prédire si un visage est présent dans une image donnée. Dans ce Colab, nous découperons les données en fonction du sexe pour observer s'il existe des différences significatives entre les performances du modèle pour différents groupes de genre.

S'il y a plus d'un visage dans une image, le sexe est étiqueté comme "MANQUANT".

Nous avons hébergé l'ensemble de données sur Google Cloud Platform pour plus de commodité. Exécutez le code suivant pour télécharger les données de GCP, les données prendront environ une minute à télécharger et à analyser.

data_location = tf.keras.utils.get_file('lfw_dataset.tf', 'https://storage.googleapis.com/facessd_dataset/lfw_dataset.tfrecord')

stats = tfdv.generate_statistics_from_tfrecord(data_location=data_location)
tfdv.visualize_statistics(stats)

Rendre les indicateurs d'équité

Rendez le widget Indicateurs d'équité avec les résultats d'évaluation exportés.

Ci-dessous, vous verrez des graphiques à barres affichant les performances de chaque tranche de données sur les métriques sélectionnées. Vous pouvez ajuster la tranche de comparaison de base ainsi que le ou les seuils affichés à l'aide des menus déroulants en haut de la visualisation.

Une métrique pertinente pour ce cas d'utilisation est le taux de vrais positifs, également appelé rappel. Utilisez le sélecteur sur le côté gauche pour choisir le graphique pour true_positive_rate. Ces valeurs métriques correspondent aux valeurs affichées sur la carte modèle .

Pour certaines photos, le sexe est étiqueté comme jeune au lieu d'homme ou de femme, si la personne sur la photo est trop jeune pour être annotée avec précision.
