Machine Learning Author: louwill Machine Learning Lab Although deep learning is currently dominant, Boosting algorithms represented by XGBoost, LightGBM, and CatBoost still have a wide range of applications. Excluding the unstructured data applications suitable for deep learning, such as images, text, speech, and video, Boosting algorithms remain the first choice for structured data with fewer … Read more
Source: I learned at Xuecheng This article is about 3400 words and is recommended to read in 5 minutes. It evaluates the performance of models from the perspectives of speed and accuracy. Boosting algorithms are a class of machine learning algorithms that build a strong classifier by iteratively training a series of weak classifiers (usually … Read more
Author: louwill Although deep learning is currently very popular, Boosting algorithms represented by XGBoost, LightGBM, and CatBoost still have a wide range of applications. Leaving aside the applications of deep learning suitable for unstructured data such as images, text, speech, and video, Boosting algorithms remain the first choice for structured data with fewer training samples. … Read more
This article provides an overview of the content: 1. Introduction to CatBoost CatBoost is a machine learning library open-sourced by the Russian search giant Yandex in 2017 and is a type of Boosting algorithm. CatBoost, along with XGBoost and LightGBM, is known as one of the three mainstream tools for GBDT, all of which are … Read more
1. Introduction In the field of machine learning, the interpretability of models has always been an important research direction. Today, we would like to introduce a powerful R package — explainer, which provides strong support for understanding complex classification and regression models. This package mainly achieves detailed interpretation of complex models through Shapley analysis, which … Read more
