Le composant d'ingénierie des fonctionnalités de TensorFlow Extended (TFX)

Ce portable exemple COLAB fournit un exemple un peu plus avancé de la façon dont tensorflow Transformer ( tf.Transform ) peut être utilisé pour les données prétraiter en utilisant exactement le même code pour la formation d' un modèle et de servir des conclusions dans la production.

TensorFlow Transform est une bibliothèque de prétraitement des données d'entrée pour TensorFlow, y compris la création de fonctionnalités qui nécessitent un passage complet sur l'ensemble de données d'entraînement. Par exemple, en utilisant TensorFlow Transform, vous pouvez :

Normaliser une valeur d'entrée en utilisant la moyenne et l'écart type
Convertir des chaînes en nombres entiers en générant un vocabulaire sur toutes les valeurs d'entrée
Convertir des flottants en entiers en les affectant à des buckets, en fonction de la distribution des données observée

TensorFlow prend en charge les manipulations sur un seul exemple ou un lot d'exemples. tf.Transform étend ces capacités à l' appui complet passe sur le jeu de données de formation ensemble.

La sortie de tf.Transform est exportée sous forme de graphique de tensorflow que vous pouvez utiliser pour la formation et au service. L'utilisation du même graphique pour l'entraînement et la diffusion peut éviter le biais, car les mêmes transformations sont appliquées aux deux étapes.

Ce que nous faisons dans cet exemple

Dans cet exemple , nous allons le traitement d' un ensemble de données largement utilisé contenant des données de recensement , et la formation d' un modèle pour faire le classement. En chemin , nous allons transformer les données en utilisant tf.Transform .

Pip de mise à niveau

Pour éviter de mettre à niveau Pip dans un système lors de l'exécution locale, assurez-vous que nous exécutons dans Colab. Les systèmes locaux peuvent bien sûr être mis à niveau séparément.

try:
  import colab
  !pip install --upgrade pip
except:
  pass

Installer la transformation TensorFlow

pip install tensorflow-transform

Vérification Python, importations et globals

Nous allons d'abord nous assurer que nous utilisons Python 3, puis installer et importer les éléments dont nous avons besoin.

import sys

# Confirm that we're using Python 3
assert sys.version_info.major == 3, 'Oops, not running Python 3. Use Runtime > Change runtime type'

import math
import os
import pprint

import tensorflow as tf
print('TF: {}'.format(tf.__version__))

import apache_beam as beam
print('Beam: {}'.format(beam.__version__))

import tensorflow_transform as tft
import tensorflow_transform.beam as tft_beam
print('Transform: {}'.format(tft.__version__))

Prétraiter avec `tf.Transform`

Créer un `tf.Transform` preprocessing_fn

La fonction est prétraiter le concept le plus important de la tf.Transform. Une fonction de prétraitement est l'endroit où la transformation de l'ensemble de données se produit réellement. Il accepte et retourne un dictionnaire de tenseurs, où un tenseur signifie un Tensor ou SparseTensor . Il existe deux groupes principaux d'appels d'API qui constituent généralement le cœur d'une fonction de prétraitement :

Tensorflow Ops: Toute fonction qui accepte et retourne tenseurs, ce qui signifie généralement ops tensorflow. Celles-ci ajoutent au graphique des opérations TensorFlow qui transforment les données brutes en données transformées, un vecteur de caractéristiques à la fois. Ceux-ci fonctionneront pour chaque exemple, à la fois pendant l'entraînement et le service.
Tensorflow Transformer Analyzers: Tous des analyseurs fournis par tf.Transform. Les analyseurs acceptent et renvoient également les tenseurs, mais contrairement aux opérations TensorFlow, ils ne s'exécutent qu'une seule fois, pendant l'entraînement, et effectuent généralement un passage complet sur l'ensemble des données d'entraînement. Ils créent tenseur des constantes , qui sont ajoutés à votre graphique. Par exemple, tft.min calcule le minimum d'un tenseur sur l'ensemble de données de formation. tf.Transform fournit un ensemble fixe d'analyseurs, mais cela sera étendu dans les futures versions.

Transformer les données

Nous sommes maintenant prêts à commencer à transformer nos données dans un pipeline Apache Beam.

Transformez-le à l'aide d'un pipeline de prétraitement qui met à l'échelle les données numériques et convertit les données catégorielles des chaînes en indices de valeurs int64, en créant un vocabulaire pour chaque catégorie
Écrivez le résultat comme TFRecord de Example Protos, que nous utiliserons pour la formation d' un modèle plus tard

Terme clé: Apache faisceau utilise une syntaxe spéciale pour définir et Invoke transforme . Par exemple, dans cette ligne :

result = pass_this | 'name this step' >> to_this_call

La méthode to_this_call est invoquée et passé l'objet appelé pass_this , et cette opération sera appelée name this step de name this step dans une trace de pile . Le résultat de l'appel à to_this_call est retourné en result . Vous verrez souvent les étapes d'un pipeline enchaînées comme ceci :

result = apache_beam.Pipeline() | 'first step' >> do_this_first() | 'second step' >> do_this_last()

et depuis que cela a commencé avec un nouveau pipeline, vous pouvez continuer comme ceci :

next_result = result | 'doing more stuff' >> another_function()

Utiliser nos données prétraitées pour entraîner un modèle à l'aide de tf.keras

Pour montrer comment tf.Transform nous permet d'utiliser le même code pour la formation et le service, et éviter ainsi biais, nous allons former un modèle. Pour entraîner notre modèle et préparer notre modèle entraîné pour la production, nous devons créer des fonctions d'entrée. La principale différence entre notre fonction d'entrée d'entraînement et notre fonction d'entrée de service est que les données d'entraînement contiennent les étiquettes, contrairement aux données de production. Les arguments et les retours sont également quelque peu différents.

Ce que nous avons fait

Dans cet exemple , nous avons utilisé tf.Transform pour prétraiter un ensemble de données des données de recensement, et de former un modèle avec les données nettoyées et transformées. Nous avons également créé une fonction d'entrée que nous pourrions utiliser lorsque nous déployons notre modèle formé dans un environnement de production pour effectuer une inférence. En utilisant le même code pour l'entraînement et l'inférence, nous évitons tout problème d'asymétrie des données. En cours de route, nous avons appris à créer une transformation Apache Beam pour effectuer la transformation dont nous avions besoin pour nettoyer les données. Nous avons vu également comment utiliser ces données transformées pour former un modèle en utilisant soit tf.keras ou tf.estimator . Ce n'est qu'une petite partie de ce que TensorFlow Transform peut faire ! Nous vous encourageons à plonger dans tf.Transform et de découvrir ce qu'il peut faire pour vous.
