We propose a method for optimizing the parameters (magnetic field, current, and damping constant) of the LLG equation, which describes the dynamics of a spin torque oscillator, using the gradient descent method. We then apply this method to parameter estimation tasks and image recognition tasks (MNIST, CIFAR-10) to demonstrate that tuning the parameters of the LLG equation improves accuracy.
