CatBoost [6] is an open-source software library developed by Yandex. It provides a gradient boosting framework which, among other features, attempts to solve for categorical features using a permutation-driven alternative to the classical algorithm. [ 7 ]
LightGBM, short for Light Gradient-Boosting Machine, is a free and open-source distributed gradient-boosting framework for machine learning, originally developed by Microsoft.
Friedman introduced his regression technique as a "Gradient Boosting Machine" (GBM). [4] Mason, Baxter et al. described the generalized abstract class of algorithms as "functional gradient boosting". [ 5 ] [ 6 ] Friedman et al. describe an advancement of gradient boosted models as Multiple Additive Regression Trees (MART); [ 18 ] Elith et al ...
Provides classification and regression datasets in a standardized format that are accessible through a Python API. Metatext NLP: https://metatext.io/datasets web repository maintained by community, containing nearly 1000 benchmark datasets, and counting. Provides many tasks from classification to QA, and various languages from English ...
Soon after, the Python and R packages were built, and XGBoost now has package implementations for Java, Scala, Julia, Perl, and other languages. This brought the library to more developers and contributed to its popularity among the Kaggle community, where it has been used for a large number of competitions.
From January 2008 to December 2012, if you bought shares in companies when Woodrow A. Myers Jr., MD joined the board, and sold them when he left, you would have a 48.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
Stochastic gradient descent has been used since at least 1960 for training linear regression models, originally under the name ADALINE. [ 25 ] Another stochastic gradient descent algorithm is the least mean squares (LMS) adaptive filter.
