Deep Learning V2 Pytorch
Ce projet est une collection de supports de cours sur le deep learning avec PyTorch, composée de projets pratiques et d'exercices de programmation. Il se concentre sur l'implémentation d'architectures de réseaux de neurones et l'entraînement de modèles pour résoudre des problèmes de données complexes.
Le dépôt inclut une suite de projets de vision par ordinateur pour construire des classificateurs d'images, des auto-encodeurs et des applications de transfert de style. Il propose un laboratoire sur les réseaux antagonistes génératifs (GAN) pour créer des images synthétiques et des implémentations spécifiques pour le transfert d'apprentissage afin d'adapter des poids pré-entraînés à de nouvelles tâches.
La base de code couvre l'analyse de données séquentielles pour le traitement du langage naturel (NLP) en utilisant des réseaux de neurones récurrents et des plongements de mots (word embeddings). Des capacités supplémentaires incluent le prétraitement des données d'image, l'évaluation des performances des modèles et le déploiement de modèles entraînés sur une infrastructure cloud.
Les supports sont fournis sous forme de série de Jupyter Notebooks.
