Researchers have developed a novel hybrid methodology to enhance the accuracy of the SABR implied volatility formula by integrating machine learning with analytical structures. This approach augments neural network inputs with geometric features from the SABR model's stochastic differential equations and trains the network to correct residual errors from Hagan's approximation. The resulting model offers improved accuracy and robustness over traditional methods, making it suitable for real-time financial applications. AI
