\nBonjour ! J’ai un ensemble de donn\u00e9es contenant des informations sur diff\u00e9rents produits vendus dans un magasin, notamment leur nom, leur cat\u00e9gorie, leur prix d’achat, leur prix de vente, et la quantit\u00e9 vendue chaque mois pendant une ann\u00e9e. Je souhaiterais cr\u00e9er un mod\u00e8le pr\u00e9dictif, probablement en utilisant l’apprentissage automatique, pour estimer les ventes futures de chaque produit, en tenant compte des tendances saisonni\u00e8res et des relations potentielles entre les diff\u00e9rentes cat\u00e9gories de produits. Par exemple, est-ce que la vente d’un certain type de produit augmente g\u00e9n\u00e9ralement lorsque les ventes d’un autre produit augmentent \u00e9galement ? Y a-t-il des p\u00e9riodes de l’ann\u00e9e (No\u00ebl, soldes d’\u00e9t\u00e9, etc.) qui influencent particuli\u00e8rement les ventes de certains produits ? De plus, comment puis-je \u00e9valuer la performance de mon mod\u00e8le et d\u00e9terminer quels sont les produits pour lesquels la pr\u00e9diction est la plus pr\u00e9cise ou la moins pr\u00e9cise ? Quels algorithmes d’apprentissage automatique seraient les plus adapt\u00e9s pour ce type de probl\u00e8me de pr\u00e9diction de s\u00e9ries temporelles avec des variables cat\u00e9gorielles et potentiellement des relations entre les produits ? Enfin, est-ce qu’il existe des librairies Python sp\u00e9cifiques (comme Prophet, ARIMA, ou des mod\u00e8les bas\u00e9s sur des r\u00e9seaux de neurones r\u00e9currents) que vous me conseilleriez d’utiliser et comment je pourrais les impl\u00e9menter efficacement dans mon projet ? Je cherche une approche pragmatique et des conseils pratiques pour construire et \u00e9valuer un mod\u00e8le de pr\u00e9diction des ventes fiable. Merci d’avance pour votre aide !<\/p>\n
