New neural operator slashes financial model calibration time

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel neural operator designed to significantly speed up the calibration process for local-stochastic volatility (LSV) models in quantitative finance. This new method, implemented using Deep Operator Networks (DeepONet) and Fourier Neural Operators (FNO), can perform calibration in milliseconds, a drastic reduction from the previous 98.5 ms. The projection-consistent operator ensures static-arbitrage constraints and improves accuracy, reducing local-volatility root-mean-square error by 36% and leverage root-mean-square error by 7-16% in synthetic tests.

    Amortizing the Calibration Triple: A Projection-Consistent Neural Operator for Local-Stochastic Volatility

    arXiv:2608.01217v1 Announce Type: cross Abstract: Local-stochastic volatility (LSV) combines vanilla marginals with richer smile dynamics, but calibration requires a slow, noisy and sequential McKean--Vlasov fixed point. We learn a projection-consistent operator for the calibrati…
