Boost-R: Gradient boosted trees for recurrence data [PDF]

open access: yesJournal of Quality Technology, 2021
Recurrence data arise from multi-disciplinary domains spanning reliability, cyber security, healthcare, online retailing, etc. This paper investigates an additive-tree-based approach, known as Boost-R (Boosting for Recurrence Data), for recurrent event data with both static and dynamic features.

Gradient boosting for quantitative finance

open access: yesThe Journal of Computational Finance, 2021
In this paper, we discuss how tree-based machine learning techniques can be used in the context of derivatives pricing. Gradient boosted regression trees are employed to learn the pricing map for a couple of classical, time-consuming problems in quantitative finance.

Gradient boosting with extreme-value theory for wildfire prediction

open access: yes, 2022
This paper details the approach of the team $\textit{Kohrrelation}$ in the 2021 Extreme Value Analysis data challenge, dealing with the prediction of wildfire counts and sizes over the contiguous US. Our approach uses ideas from extreme-value theory in a

Fusion and Classification of SAR and Optical Data Using Multi-Image Color Components with Differential Gradients

open access: yesRemote Sensing, 2023
This paper proposes a gradient-based data fusion and classification approach for Synthetic Aperture Radar (SAR) and optical image. This method is used to intuitively reflect the boundaries and edges of land cover classes present in the dataset.

Accelerating Gradient Boosting Machine

open access: yesCoRR, 2019
Gradient Boosting Machine (GBM) is an extremely powerful supervised learning algorithm that is widely used in practice. GBM routinely features as a leading algorithm in machine learning competitions such as Kaggle and the KDDCup. In this work, we propose Accelerated Gradient Boosting Machine (AGBM) by incorporating Nesterov's acceleration techniques ...
