本文研究了一种正则化方法在泊松噪声干扰下的反问题中的性质,该方法以Kullback-Leibler散度为数据项。根据Morozov型原理选择正则化参数。我们表明,这种方法的参数的选择是明确的。这种后验选择导致收敛的正则化方法。当源条件满足时,给出了正则化参数后验选择的收敛速度。
We study the properties of a regularization method for inverse problems corrupted by Poisson noise with Kullback-Leibler divergence as data term. The regularization parameter is chosen according to a Morozov type principle. We show that this method of choice of the parameter is well-defined. This a posteriori choice leads to a convergent regularization method. Convergences rates are obtained for this a posteriori choice of the regularization parameter when some source condition is satisfied.
