我们研究了一个随机过程的强化,它的发展以下的动态一个给定的扩散过程在一个有界的区域,并根据其占领措施时,它到达边界重新采样。我们表明,其占领措施收敛到唯一的准平稳分布的扩散过程中吸收的边界的域。我们的证明使用准平稳分布理论和随机逼近技术的最新成果。
We study a random process with reinforcement, which evolves following the dynamics of a given diffusion process in a bounded domain and is resampled according to its occupation measure when it reaches the boundary. We show that its occupation measure converges to the unique quasi-stationary distribution of the diffusion process absorbed at the boundary of the domain. Our proofs use recent results in the theory of quasi-stationary distributions and stochastic approximation techniques.
