本文提出了一种自适应算法，迭代更新混合重要抽样密度的权值和分量参数，以优化用熵准则度量的重要抽样性能。结果表明，该方法适用于重要抽样密度的广泛类别，其中特别包括多元学生t分布的混合。在人工和实际的例子中研究了该方案的性能，特别强调了一种新的Rao-Blackwellisation设备的优点，该设备可以很容易地结合在更新方案中。

英文摘要：
  In this paper, we propose an adaptive algorithm that iteratively updates both the weights and component parameters of a mixture importance sampling density so as to optimise the importance sampling performances, as measured by an entropy criterion. The method is shown to be applicable to a wide class of importance sampling densities, which includes in particular mixtures of multivariate Student t distributions. The performances of the proposed scheme are studied on both artificial and real examples, highlighting in particular the benefit of a novel Rao-Blackwellisation device which can be easily incorporated in the updating scheme.
