Deep kernel hedging framework combines neural networks and kernel methods

Researchers have introduced a novel deep kernel hedging framework that merges deep learning's adaptability with the structural biases of kernel methods. This approach parameterizes the kernel through a neural network embedding of input features, minimizing regularized empirical risk. The framework can incorporate path-dependent information using signature features and includes a scalable random Fourier feature approximation to manage computational costs. Evaluations on synthetic and real data demonstrate competitive and robust hedging performance, especially in low-data scenarios, underscoring the synergy between neural representations and kernel methods.
