报告题目：Variational inference of the drift function for stochastic differential equations driven by Lévy processes.
报告摘要：In this talk, we consider the nonparametric estimation problem of the drift function of stochastic differential equations driven by α-stable Lévy motion. First, the Kullback-Leibler divergence between the path probabilities of two stochastic differential equations with different drift functions is optimized. The variational formula based on the stationary Fokker-Planck equation is constructed via the Lagrangian multiplier. Then combined with the data information, the empirical distribution is used to replace the stationary density, and the drift function is estimated non-parametrically from the perspective of the process.
