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.

Causal Gradient Boosting: Boosted Instrumental Variable Regression

open access: yesProceedings of the 23rd ACM Conference on Economics and Computation, 2022
Recent advances in the literature have demonstrated that standard supervised learning algorithms are ill-suited for problems with endogenous explanatory variables. To correct for the endogeneity bias, many variants of nonparameteric instrumental variable regression methods have been developed.
