Des données brutes aux caractéristiques

L'extraction de caractéristiques est souvent la phase la plus longue et la plus difficile du développement de votre projet de ML. Dans le processus d'extraction de caractéristiques, vous partez de vos données brutes et utilisez votre propre connaissance du domaine pour créer des caractéristiques qui feront fonctionner vos algorithmes de ML. Dans ce module, nous explorerons ce qui constitue une bonne caractéristique et découvrirons comment la représenter dans votre modèle de ML.

Extraction de caractéristiques

Ce module examine les différences entre le machine learning et les statistiques, et comment effectuer une extraction de caractéristiques dans BigQuery ML et Keras. Nous aborderons également certaines pratiques avancées d'extraction de caractéristiques.

Prétraiter et créer des caractéristiques

Dans ce module, vous en apprendrez plus sur Dataflow, une technologie complémentaire d'Apache Beam. Grâce à ces deux technologies, vous pouvez créer et accéder à des fonctionnalités de prétraitement et d'extraction de caractéristiques.

Croisements de caractéristiques – TensorFlow Playground

Dans le machine learning traditionnel, les croisements de caractéristiques ne jouent pas un rôle très important, mais dans les méthodes modernes, ils constituent un outil à la valeur inestimable. Dans ce module, vous apprendrez à reconnaître les types de problèmes pour lesquels les croisements de caractéristiques constituent un outil puissant aidant les machines à apprendre.

Présentation de TensorFlow Transform

TensorFlow Transform (tf.Transform) est une bibliothèque de prétraitement des données avec TensorFlow qui est utile pour les prétraitements nécessitant un passage complet des données, comme : - la normalisation d'une valeur d'entrée par la moyenne et l'écart type - la conversion de chaînes en nombres entiers en générant un vocabulaire sur toutes les valeurs d'entrée - la mise en buckets des entrées basées sur la distribution des données observées Dans ce module, nous allons explorer les cas d'utilisation de tf.Transform.

Reviews summary

Feature engineering course

There is only one review for this course, and the tone is decidedly negative. The reviewer takes particular issue with the labs in this course. Given the lack of additional reviews, we are unable to give a confident summary of this course.

The labs are a “nightmare”.
