Ce dépôt fournit une collection d'algorithmes de machine learning implémentés à partir de zéro en Python pur. Il sert de ressource pédagogique conçue pour démontrer la logique interne et les fondements mathématiques des modèles prédictifs sans dépendre de frameworks de machine learning externes ou de bibliothèques « boîte noire ». Le projet se distingue en mappant directement les implémentations de code à leurs formules statistiques et calculatoires sous-jacentes. Chaque modèle est construit en utilisant des primitives de langage de base et une optimisation manuelle par descente de gradient, permettant aux utilisateurs d'observer les mécanismes des dérivées partielles et des mises à jour de poids pendant le processus d'entraînement. Les implémentations utilisent des composants modulaires et des calculs vectorisés sur tableaux pour simuler la structure des opérations d'algèbre linéaire de haut niveau. Cette approche facilite la recherche sur l'architecture algorithmique et soutient le développement de compétences en science des données en exposant le raisonnement étape par étape nécessaire pour traiter les données et minimiser les fonctions de perte. Le dépôt consiste en une série de Jupyter Notebooks qui documentent la dérivation et la construction de ces modèles.
