Monte Carlo Simulation of an American Option [PDF]

Journal of Systemics, Cybernetics and Informatics, 2007
We implement gradient estimation techniques for sensitivity analysis of option pricing which can be efficiently employed in Monte Carlo simulation. Using these techniques we can simultaneously obtain an estimate of the option value together with the ...

Condensed-gradient boosting

International Journal of Machine Learning and Cybernetics
Abstract This paper presents a computationally efficient variant of Gradient Boosting (GB) for multi-class classification and multi-output regression tasks. Standard GB uses a 1-vs-all strategy for classification tasks with more than two classes. This strategy entails that one tree per class and iteration has to be trained.
