Optimization by Gradient Boosting [PDF]

open access: yes, 2021
Gradient boosting is a state-of-the-art prediction technique that sequentially produces a model in the form of linear combinations of simple predictors---typically decision trees---by solving an infinite-dimensional convex optimization problem. We provide in the present paper a thorough analysis of two widespread versions of gradient boosting, and ...

Online Gradient Boosting

open access: yesCoRR, 2015
We extend the theory of boosting for regression problems to the online learning setting. Generalizing from the batch setting for boosting, the notion of a weak learning algorithm is modeled as an online learning algorithm with linear loss functions that competes with a base class of regression functions, while a strong learning algorithm is an online ...

Gradient boosting [PDF]

open access: yes, 2021
Tiivistelmä. Tässä tutkielmassa käsitellään Gradient boosting algoritmia. Algoritmi käsittelee ohjatun oppimisen menetelmin läpi dataa ja pyrkii tekemään tämän avulla luotettavia ennusteita. Tutkielmassa käydään läpi yleisesti ohjattua oppimista ja päätöspuita sekä verrataan mahdollisia muita samankaltaisia menetelmiä.

Gradient-Free Gradient Boosting [PDF]

open access: yes, 2020
Motivated by applications in fraud detection, this dissertation is concerned about model selection in predictive models where the correct ranking of observations has to be predicted. For this, the thesis starts by proving the asymptotic linearity of a whole family of regularized M-estimators which covers for example the Lasso.

Randomized Gradient Boosting Machine [PDF]

open access: yesSIAM Journal on Optimization, 2020
The Gradient Boosting Machine (GBM) introduced by Friedman [J. H. Friedman, Ann. Statist., 29 (2001), pp. 1189--1232] is a powerful supervised learning algorithm that is very widely used in practice---it routinely features as a leading algorithm in machine learning competitions such as Kaggle and the KDDCup.

Gradient boosted feature selection [PDF]

open access: yesProceedings of the 20th ACM SIGKDD international conference on Knowledge discovery and data mining, 2014
A feature selection algorithm should ideally satisfy four conditions: reliably extract relevant features; be able to identify non-linear feature interactions; scale linearly with the number of features and dimensions; allow the incorporation of known sparsity structure.

Gradient boosting to boost the efficiency of hydraulic fracturing [PDF]

open access: yesJournal of Petroleum Exploration and Production Technology, 2019
In this paper, we present a data-driven model for forecasting the production increase after hydraulic fracturing (HF). We use data from fracturing jobs performed at one of the Siberian oilfields. The data includes features, characterizing the jobs, and geological information.
