About Khaled

Bonjour,

Freelance Data Scientist, Diplômé en master statistiques desprocessus aléatoires et intervenant en Data Science à l'université Mentouri de Constantine Algérie. Ayant déjà travailler sur des projets de machine learning, analyse des données et natura language processing notamment un "fake news detector", je souhaite apporter mon expertise pour vous accompagner sur les problématiques liées à l'analyse et au traitement de vos données.

Mon expertise :

- Data Science : création de modèles prédictifs de type régression/classification/text mining/NLP
- Analyse fonctionnelle: compréhension et formalisation du besoin dans un langage clair et concis
- Données : web scraping, extraction, mise en forme, exploitation des données

Mes principaux outils de travail :
- Python avec les librairies Scikit Learn pour les algorithmes prédictifs de type Machine Learning, Pandas pour l'extraction des données/exploitation des données, Matplotlib & Seaborn pour la visualisation.
- Le langage SQL pour interroger vos base de données


Je me ferai un plaisir d'échanger avec vous sur vos problématiques.

Khaled.
