Data Science
La data science, et plus généralement l'Intelligence Artificielle (IA), se distingue de la programmation et de l'analyse traditionnelle par sa capacité à extraire des connaissances à partir de données et modifier son comportement (c’est-à-dire apprendre) sans programmation spécifique. Alors que les logiciels traditionnels prédéfinissent la logique qui régit leurs processus, les algorithmes de data science construisent et découvrent des modèles et sont en capacité de les améliorer continuellement.
La data science regroupe un ensemble de compétence incluant le Machine Learning, le traitement automatique du langage naturel (NLP pour Natural Language Processing), ou encore la reconnaissance de la parole, des images et des visages (entre autres applications). Dans certaines applications, les algorithmes vont jusqu'à simuler l’intelligence humaine.
Points clés essentiels
- Les data scientists construisent, entrainent, et valident les modèles pour prendre des décisions critiques.
- Les Data Scientists gèrent l'accès aux données, la reproductibilité et la collaboration afin de créer rapidement des modèles déployables à grande échelle.
- Adaltas permet aux Data Scientists de créer, mettre à l'échelle et déployer facilement des modèles de machine learning en quelques minutes, contribuant ainsi à stimuler l'innovation dans l'ensemble de l'entreprise.
