Definition of Gradient Boosting Gradient Boosting: Gradient boosting is a machine learning technique that combines a number of weaker models to produce a stronger model. It does this by constructing a model that takes into account the predictions of the weaker models, and uses this information to make its own predictions. What is Gradient Boosting…
Definition of Model A model is a representation of something in order to understand it or predict its behavior. In machine learning, a model is a mathematical function that is used to predict the value of a target variable, given a set of input variables. How is a Model used? A Model is a mathematical…
Definition of Quartile Quartile: A quartile is a statistic that divides a data set into four equal parts. The first quartile is the lowest 25% of the data, the second quartile is the lower 50% of the data, the third quartile is the upper 50% of the data, and the fourth quartile is the highest…
