Gordon Lee et al introduce a data-driven and model-agnostic approach for computing conditional expectations. The new method combines classical techniques with machine learning methods, in particular Gaussian process regression and kernel density estimation stabilised with a control variate. The method is applied to pricing and hedging of (multidimensional) exotic options for different models, including the rough Bergomi model
