Entraîner un modèle AutoML (API Vertex AI)

Cette page explique comment entraîner un modèle AutoML à l'aide de l'API d'IA Vertex.

Pour en savoir plus sur l'utilisation de la console Google Cloud afin d'entraîner un modèle AutoML, consultez la page Entraîner un modèle AutoML à l'aide de Google Cloud Console.

Avant de commencer

Avant d'entraîner un modèle, vous devez préparer vos données d'entraînement et créer un ensemble de données.

Entraîner un modèle AutoML à l'aide de l'API

Lorsque vous entraînez un modèle à l'aide de l'API, vous créez un objet TrainingPipeline, en spécifiant l'ensemble de données contenant vos données d'entraînement.

Sélectionnez votre type de données ci-dessous :

Image

Sélectionnez l'onglet correspondant à votre objectif :

Classification

Sélectionnez l'onglet correspondant à votre langage ou à votre environnement :

API REST et ligne de commande

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

LOCATION : région d'emplacement de l'ensemble de données et de création du modèle. Exemple : us-central1.
PROJECT : ID de votre projet
TRAININGPIPELINE_DISPLAYNAME : valeur obligatoire. Nom à afficher pour le trainingPipeline.
DATASET_ID : ID de l'ensemble de données à utiliser pour l'entraînement.
fractionSplit : facultatif. Une des nombreuses options de répartition possibles en cas d'utilisation de ML pour vos données. Pour fractionSplit, les valeurs doivent être égales à 1. Par exemple :
- {"trainingFraction": "0.7","validationFraction": "0.15","testFraction": "0.15"}
MODEL_DISPLAYNAME^* : nom à afficher pour le modèle importé (créé) par le TrainingPipeline.
MODEL_DESCRIPTION^* : description du modèle.
modelToUpload.labels^* : tout ensemble de paires clé/valeur pour organiser vos modèles. Exemple :
- "env" : "prod"
- "tier" : "backend"
MODELTYPE^† : type de modèle hébergé dans le cloud à entraîner. Vous disposez des options suivantes :
- CLOUD (par défaut)
NODE_HOUR_BUDGET^† : le coût réel de l'entraînement sera égal ou inférieur à cette valeur. Pour les modèles cloud, le budget doit être compris entre 8 000 et 800 000 milli-nœuds-heure (inclus). La valeur par défaut est de 192 000, ce qui correspond à une durée d'exécution d'une journée, en supposant que 8 nœuds sont utilisés.
PROJECT_NUMBER : numéro de votre projet

Sélectionnez l'onglet correspondant à votre langage ou à votre environnement :

API REST et ligne de commande

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

LOCATION : région d'emplacement de l'ensemble de données et de création du modèle. Exemple : us-central1.
PROJECT : ID de votre projet
TRAININGPIPELINE_DISPLAYNAME : valeur obligatoire. Nom à afficher pour le trainingPipeline.
DATASET_ID : ID de l'ensemble de données à utiliser pour l'entraînement.
fractionSplit : facultatif. Une des nombreuses options de répartition possibles en cas d'utilisation de ML pour vos données. Pour fractionSplit, les valeurs doivent être égales à 1. Par exemple :
- {"trainingFraction": "0.7","validationFraction": "0.15","testFraction": "0.15"}
MODEL_DISPLAYNAME^* : nom à afficher pour le modèle importé (créé) par le TrainingPipeline.
MODEL_DESCRIPTION^* : description du modèle.
modelToUpload.labels^* : tout ensemble de paires clé/valeur pour organiser vos modèles. Exemple :
- "env" : "prod"
- "tier" : "backend"
MODELTYPE^† : type de modèle hébergé dans le cloud à entraîner. Vous disposez des options suivantes :
- CLOUD-HIGH-ACCURACY-1 : modèle optimal pour une utilisation dans Google Cloud et impossible à exporter. Ce modèle doit générer une latence plus élevée, mais la qualité des prédictions est également censée être supérieure à celle des autres modèles cloud.
- CLOUD-LOW-LATENCY-1 : modèle optimal pour une utilisation dans Google Cloud et impossible à exporter. Ce modèle doit générer une faible latence, mais la qualité des prédictions peut s'avérer inférieure à celle des autres modèles cloud.
NODE_HOUR_BUDGET^† : le coût réel de l'entraînement sera égal ou inférieur à cette valeur. Pour les modèles cloud, le budget doit être compris entre 20 000 et 900 000 milli-nœuds-heure (inclus). La valeur par défaut est de 216 000, ce qui correspond à une durée d'exécution d'une journée, en supposant que 9 nœuds sont utilisés.
PROJECT_NUMBER : numéro de votre projet

Méthode HTTP et URL :

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT/locations/LOCATION/trainingPipelines

Sélectionnez un onglet pour votre langage ou environnement :

API REST et ligne de commande

Vous utilisez la commande trainingPipelines.create pour entraîner un modèle.

Entraîner le modèle

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

LOCATION : votre région.
PROJECT : ID de votre projet
TRAINING_PIPELINE_DISPLAY_NAME : nom à afficher du pipeline d'entraînement créé pour cette opération.
TRAINING_TASK_DEFINITION : méthode d'entraînement du modèle
- AutoML : un bon choix pour un large éventail de cas d'utilisation.
  gs://google-cloud-aiplatform/schema/trainingjob/definition/automl_forecasting_1.0.0.yaml
- Seq2Seq+ : un bon choix pour l'expérimentation. L'algorithme est susceptible de converger plus rapidement qu'AutoML, car son architecture est plus simple et il utilise un espace de recherche plus petit. Nos tests montrent que Seq2Seq+ offre de bons résultats avec un petit budget-temps et des ensembles de données dont la taille est inférieure à 1 Go.
  gs://google-cloud-aiplatform/schema/trainingjob/definition/seq2seq_plus_time_series_forecasting_1.0.0.yaml
TARGET_COLUMN : colonne (valeur) que le modèle doit prédire.
TIME_COLUMN : colonne Heure. En savoir plus
TIME_SERIES_IDENTIFIER_COLUMN : colonne de l'identifiant de série temporelle. En savoir plus
WEIGHT_COLUMN (facultatif) : colonne de pondération. En savoir plus
TRAINING_BUDGET : durée maximale pendant laquelle le modèle doit être entraîné, en milli-nœuds-heure (1 000 milli-nœuds-heure correspondent à un nœud-heure).
GRANULARITY_UNIT : unité à utiliser pour la précision de vos données d'entraînement, de l'horizon de prévision et de la fenêtre de contexte. Il peut s'agir de minute, hour, day, week, month ou year. Sélectionnez day si vous souhaitez utiliser la modélisation des effets des jours fériés. En savoir plus
GRANULARITY_QUANTITY : nombre d'unités de précision qui composent l'intervalle entre les observations dans vos données d'entraînement. Doit être égal à un pour toutes les unités sauf les minutes, pouvant correspondre à 1, 5, 10, 15 ou 30. En savoir plus
GROUP_COLUMNS : noms de colonne de votre table d'entrée d'entraînement qui identifient le regroupement au niveau de la hiérarchie. La ou les colonnes doivent être "time_series_attribute_columns". Apprenez-en plus.
GROUP_TOTAL_WEIGHT : pondération de la perte agrégée du groupe par rapport à la perte individuelle. Désactivée si la valeur est définie sur "0.0" ou n'est pas définie. Si la colonne de groupe n'est pas définie, toutes les séries temporelles seront traitées dans le même groupe et agrégées sur toutes les séries temporelles. En savoir plus
TEMPORAL_TOTAL_WEIGHT : pondération de la perte agrégée dans le temps par rapport à la perte individuelle. Désactivée si la valeur est définie sur "0.0" ou n'est pas définie. En savoir plus
GROUP_TEMPORAL_TOTAL_WEIGHT : pondération de la perte totale (groupe x temps) par rapport à la perte individuelle. Désactivée si la valeur est définie sur "0.0" ou n'est pas définie. Si la colonne de groupe n'est pas définie, toutes les séries temporelles seront traitées dans le même groupe et agrégées sur toutes les séries temporelles. En savoir plus
HOLIDAY_REGIONS : (facultatif) une ou plusieurs régions géographiques en fonction desquelles l'effet des jours fériés est appliqué dans la modélisation. Pendant l'entraînement, Vertex AI crée des caractéristiques catégorielles de jours fériés dans le modèle en fonction de la date de la colonne Heure et des régions géographiques spécifiées. Pour activer cette fonctionnalité, définissez GRANULARITY_UNIT sur day, puis spécifiez une ou plusieurs régions dans le champ HOLIDAY_REGIONS. Par défaut, la modélisation des effets des jours fériés est désactivée.
Les valeurs acceptées sont les suivantes :
- GLOBAL : détecte les jours fériés dans toutes les régions du monde.
- NA : détecte les jours fériés en Amérique du Nord
- JAPAC : détecte les jours fériés au Japon et en Asie-Pacifique
- EMEA : détecte les jours fériés en Europe, au Moyen-Orient et en Afrique
- LAC : détecte les jours fériés en Amérique latine et dans les Caraïbes
- Codes pays ISO 3166-1 : détecte les jours fériés des pays individuels.
FORECAST_HORIZON : taille de l'horizon de prévision, spécifiée en unités de précision. L'horizon des prévisions correspond à la période pour laquelle le modèle doit prévoir les résultats. En savoir plus
CONTEXT_WINDOW : nombre d'unités de précision que le modèle doit examiner pour les inclure au moment de l'entraînement. En savoir plus
OPTIMIZATION_OBJECTIVE : obligatoire uniquement si vous ne souhaitez pas atteindre l'objectif d'optimisation par défaut pour votre type de prédiction. En savoir plus
TIME_SERIES_ATTRIBUTE_COL : nom ou noms des colonnes qui sont des attributs de série temporelle. En savoir plus
AVAILABLE_AT_FORECAST_COL : nom ou noms des colonnes covariées dont la valeur est connue au moment de la prévision. En savoir plus
UNAVAILABLE_AT_FORECAST_COL : nom ou noms des colonnes covariées dont la valeur est inconnue au moment de la prévision. En savoir plus
TRANSFORMATION_TYPE : le type de transformation est fourni pour chaque colonne utilisée pour entraîner le modèle. En savoir plus
COLUMN_NAME : nom de la colonne avec le type de transformation spécifié. Chaque colonne utilisée pour entraîner le modèle doit être spécifiée.
MODEL_DISPLAY_NAME : nom à afficher du modèle nouvellement entraîné.
DATASET_ID : ID de l'ensemble de données d'entraînement.
Vous pouvez fournir un objet Split pour contrôler votre répartition des données. Pour en savoir plus sur le contrôle de la répartition des données, consultez la section Contrôler la répartition des données à l'aide de REST.
Vous pouvez fournir un objet windowConfig pour configurer une période de prévision. Pour en savoir plus, consultez la section Configurer l'intervalle de prévision à l'aide de REST.

Contrôler la répartition des données à l'aide de REST

Vous pouvez contrôler la manière dont vos données d'entraînement sont réparties entre les ensembles d'entraînement, de validation et de test. Lorsque vous utilisez l'API Vertex AI, déterminez la répartition des données à l'aide de l'objet Split. L'objet Split peut être inclus dans l'objet InputConfig sous la forme de plusieurs types d'objets, chacun offrant une manière différente de répartir les données d'entraînement. Vous ne pouvez sélectionner qu'une seule méthode.

Les méthodes que vous pouvez utiliser pour répartir vos données dépendent du type de données :

Image, texte, vidéo

FractionSplit :
- TRAINING_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble d'entraînement.
- VALIDATION_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble de validation. Non utilisé pour les données vidéo.
- TEST_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble de test.
Si l'une des fractions est spécifiée, elles doivent toutes être spécifiées. La somme des fractions doit être égale à 1,0. Les valeurs par défaut des fractions diffèrent selon le type de données. En savoir plus
```
"fractionSplit": {
  "trainingFraction": TRAINING_FRACTION,
  "validationFraction": VALIDATION_FRACTION,
  "testFraction": TEST_FRACTION
},
```
FilterSplit :
- TRAINING_FILTER : les éléments de données correspondant à ce filtre sont utilisés pour l'ensemble d'entraînement.
- VALIDATION_FILTER : les éléments de données correspondant à ce filtre sont utilisés pour l'ensemble de validation. La valeur doit être "-" pour les données vidéo.
- TEST_FILTER : les éléments de données correspondant à ce filtre sont utilisés pour l'ensemble de test.
Ces filtres peuvent être utilisés avec l'étiquette ml_use ou avec les étiquettes que vous appliquez à vos données. Découvrez comment filtrer vos données à l'aide de l'étiquette ml-use et d'autres étiquettes.

L'exemple suivant montre comment utiliser l'objet filterSplit avec l'étiquette ml_use, avec l'ensemble de validation inclus :
```
"filterSplit": {
  "trainingFilter": "labels.aiplatform.googleapis.com/ml_use=training",
  "validationFilter": "labels.aiplatform.googleapis.com/ml_use=validation",
  "testFilter": "labels.aiplatform.googleapis.com/ml_use=test"
}
```

Tabulaire

FractionSplit :
- TRAINING_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble d'entraînement.
- VALIDATION_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble de validation. Non utilisé pour les données vidéo.
- TEST_FRACTION : fraction des données d'entraînement à utiliser pour l'ensemble de test.
Si l'une des fractions est spécifiée, elles doivent toutes être spécifiées. La somme des fractions doit être égale à 1,0. Les valeurs par défaut des fractions diffèrent selon le type de données. En savoir plus
```
"fractionSplit": {
  "trainingFraction": TRAINING_FRACTION,
  "validationFraction": VALIDATION_FRACTION,
  "testFraction": TEST_FRACTION
},
```
L'objet fractionSplit n'est pas compatible avec les modèles de prévision.
PredefinedSplit :
- DATA_SPLIT_COLUMN : colonne contenant les valeurs de répartition des données (TRAIN, VALIDATION, TEST).
Spécifiez manuellement la répartition des données pour chaque ligne à l'aide d'une colonne fractionnée. En savoir plus
```
"predefinedSplit": {
  "key": DATA_SPLIT_COLUMN
},
```
TimestampSplit :
- TRAINING_FRACTION : pourcentage des données d'entraînement à utiliser pour l'ensemble d'entraînement. La valeur par défaut est 0,80.
- VALIDATION_FRACTION : pourcentage des données d'entraînement à utiliser pour l'ensemble de validation. La valeur par défaut est 0,10.
- TEST_FRACTION : pourcentage des données d'entraînement à utiliser pour l'ensemble de test. La valeur par défaut est 0,10.
- TIME_COLUMN : colonne contenant les horodatages.
Si l'une des fractions est spécifiée, elles doivent toutes être spécifiées. La somme des fractions doit être égale à 1,0. En savoir plus

L'objet TimestampSplit n'est pas compatible avec les modèles de prévision.

  "testFraction": TEST_FRACTION
  "key": TIME_COLUMN
}
