Abstract
The Heston-Dupire model is a well-established stochastic local volatility model that offers a non-parametric representation. This model is known to closely match the implied volatility surface of options observed in the market. However, due to its non-parametric local component, Monte Carlo simulation is the only viable numerical method for derivative pricing under this model. This article proposes a novel willow tree method to replace Monte Carlo simulation for pricing exotic options and VIX options under the Heston-Dupire model. We provide the convergence rate of this method and conduct several numerical experiments to demonstrate its accuracy and efficiency. Our proposed method offers an alternative numerical technique that can enhance the computational efficiency of pricing derivatives under the Heston-Dupire model.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
