GRADIENT BOOSTING [2 records]

Record 1 2026-04-13

English

Subject field(s)
  • Artificial Intelligence
DEF

... a machine learning technique that produces a prediction model in the form of an ensemble of weak prediction models.

CONT

Gradient boosting... produces accurate predictions by combining multiple decision trees into a single model. This algorithmic approach to predictive modeling... uses base models to build upon their strengths, correcting errors and improving predictive capabilities. By capturing complex patterns in data, gradient boosting excels at diverse predictive modeling tasks.

French

Domaine(s)
  • Intelligence artificielle
CONT

L'amplification du gradient permet de tenir compte de plusieurs modèles d'un algorithme traditionnel. Cette technique peut être utilisée avec différents algorithmes comme l'arbre de décision et les forêts aléatoires [...] L'objectif principal de l'amplification du gradient est d'unifier les modèles dits faibles, afin de les rendre plus forts ensemble.

English

Subject field(s)
  • Computer Mathematics
  • Artificial Intelligence
CONT

[The] gradient boosting algorithm is an ensemble learning method based on a combination of additive models(weak learners), which can gradually learn from the previous misclassifications to create a stronger learning model. This algorithm has been complemented with a feature selection process that increases the overall performance by extracting the most relevant features from the input data.

CONT

Par rapport à un seul arbre de décision [...], l'apprentissage d'ensemble génère plusieurs arbres de décision afin d'obtenir une grande précision dans la prédiction. [...] l'algorithme d'amplification du gradient [...] combine plusieurs apprenants faibles en un apprenant fort en ajoutant séquentiellement des prédicteurs pour corriger son prédécesseur. L'erreur résiduelle est minimisée par l'ajout d'arbres [...]
