Il y a quelques années déjà, lorsque je travaillais pour l’Assurance Maladie française #CNAM (une des plus grosses bases de données santé au monde), c’est une conversation que nous avions eue avec les équipes en charge des requêtes (GDR). Aujourd’hui, les équipes de statisticiens ont changé, évolué (ce sont des #dataanalyst ou #datascientist), l’IA est apparue, mais la problématique demeure la même. La #requête, qu’elle soit en langage naturel ou dans un autre langage (en SQL, par exemple), ne permet d’obtenir des résultats exploitables que lorsque la base de données est : - à jour - sans redondance - et « propre », pour reprendre la description de Wickam (#tidydata).

Insight: Data Quality and Cleaning High-quality data is essential for effective AI analysis. Invest time in cleaning and preprocessing your data to remove errors, inconsistencies, and irrelevant information. Techniques such as normalization, handling missing values, and feature scaling will ensure that your AI models can produce accurate and reliable results.
