- Prochain rendez-vous -

Jeudi 4 mars, 14h, Séquence 3 : Problématique des données creuses de dimensions variables, l'exemple des données textuelles. Stratégies d'évaluation des modèles.
Spécificités et traitement des données creuses/textuelles. Principes de l'Embedding (Keras, CBOW, Skip-Gram) Nous reviendrons également sur les stratégies d'évaluation des modèles. Validation simple, croisée (K-fold), itérative, randomisée. Exemple proposé : Analyse de sentiment avec une analyse de critiques de films.
Durée : 2h - Les paramètres de diffusion seront précisés la veille dans le wiki

About Fidle

This repository contains all the documents and links of the Fidle Training .
Fidle (for Formation Introduction au Deep Learning) is a 2-day training session
co-organized by the Formation Permanente CNRS and the Resinfo/SARI and DevLOG CNRS networks.

The objectives of this training are :

• Understanding the bases of Deep Learning neural networks
• Develop a first experience through simple and representative examples
• Understanding Tensorflow/Keras and Jupyter lab technologies
• Apprehend the academic computing environments Tier-2 or Tier-1 with powerfull GPU

For more information, you can contact Fidle team at :
Don't forget to look at the Wiki
