用傅里叶分析精确计算归一化最大似然码长

Exact Calculation of Normalized Maximum Likelihood Code Length Using Fourier Analysis

Atsushi Suzuki, Kenji Yamanishi

摘要:

规范化最大似然码长在模型选择中得到了广泛的应用,其良好的性质,如其一致性和其统计风险的上界已经得到了论证。提出了一种基于傅里叶分析的归一化最大似然码长计算方法。我们的方法提供了一个有效的指数族模型的非渐近计算公式和一般参数模型的渐近计算公式,与以前的工作相比,具有较弱的假设。

英文摘要:

The normalized maximum likelihood code length has been widely used in model selection, and its favorable properties, such as its consistency and the upper bound of its statistical risk, have been demonstrated. This paper proposes a novel methodology for calculating the normalized maximum likelihood code length on the basis of Fourier analysis. Our methodology provides an efficient non-asymptotic calculation formula for exponential family models and an asymptotic calculation formula for general parametric models with a weaker assumption compared to that in previous work.
