Abstract(in English) | The MDL estimator is defined by the minimizer of total code length of a two part code. The smaller the redundancy of the two part code which defines the MDL estimator is, the smaller upper bound of the risk of the MDL estimator is obtained. When the true density belongs to an known exponential family, a way of construction of a two part code with small redundancy is known. However, for non-exponential families, we need to improve the two part code under some assumptions. In this paper, we discuss this problem for Huber’s contamination models, which are an example of non-exponential families. |
