Launching into Machine Learning en Français (Coursera)

À partir de l'histoire du machine learning, nous examinons les raisons pour lesquelles les réseaux de neurones fonctionnent si bien de nos jours dans différents problèmes liés à la science des données. Nous évoquons ensuite la façon d'aborder un problème d'apprentissage supervisé et le moyen d'y répondre en utilisant la descente de gradient. Cela implique de créer des ensembles de données menant à une généralisation ; nous évoquons les méthodes pour y parvenir de façon reproductible en utilisant l'expérimentation.

Course 2 of 5 in the Machine Learning with TensorFlow on Google Cloud en Français Specialization.

Syllabus

WEEK 1
Présentation du cours
Dans ce cours, vous acquerrez des connaissances de base sur le machine learning pour comprendre la terminologie que nous employons tout au long de la spécialisation. Nos professionnels Google du machine learning vous montreront également des conseils pratiques et les pièges à éviter, et vous donneront les codes et les connaissances nécessaires pour démarrer vos propres modèles de machine learning.

WEEK 2
Améliorer la qualité des données et l'analyse exploratoire des données
Dans ce module, nous allons présenter les problèmes liés à la qualité des données et les méthodes pour l'améliorer. Nous évoquerons ensuite les analyses exploratoires des données.

WEEK 3
Machine learning en pratique
Dans ce module, nous allons présenter certains des principaux types de machine learning. Nous passerons également en revue l'histoire du ML, ainsi que les événements l'ayant mené à ce système de pointe qui vous permet de développer rapidement vos connaissances en tant qu'utilisateur du ML.

WEEK 4
Optimisation
Dans ce module, nous vous expliquerons comment optimiser vos modèles de machine learning.

WEEK 5
Généralisation et échantillonnage
À présent, il est temps de répondre à une question plutôt étrange : dans quelle situation le modèle de ML le plus précis n'est-il pas le meilleur choix ? Comme indiqué dans le dernier module sur l'optimisation, la raison repose simplement sur le fait suivant : si un modèle dispose d'une métrique de perte de 0 pour l'ensemble de données d'entraînement, cela ne signifie pas qu'il fonctionnera correctement sur de nouvelles données dans le monde réel. Vous apprendrez à créer des ensembles de données d'entraînement, d'évaluation et de test reproductibles et à établir des références en matière de performances.

Advanced Algorithms and Complexity (Coursera)

You've learned the basic algorithms now and are ready to step into the area of more complex problems and algorithms to solve them. Advanced algorithms build upon basic ones and use new ideas. We will start with networks flows which are used in more typical applications such as optimal matchings, finding disjoint paths and flight scheduling as well as more surprising ones like image segmentation in computer vision.

Process Mining: Data science in Action (Coursera)

Process mining is the missing link between model-based process analysis and data-oriented analysis techniques. Through concrete data sets and easy to use software the course provides data science knowledge that can be applied directly to analyze and improve processes in a variety of domains. Data science is the profession of the future, because organizations that are unable to use (big) data in a smart way will not survive. It is not sufficient to focus on data storage and data analysis. The data scientist also needs to relate data to process analysis.
