关于两样本Behrens-Fisher问题，该研究在高维检验问题中取得新的进展。在此问题中，Chen & Qin (2010)所提出的检验统计量具有广泛的影响力。然而，在本项工作之前，如何在一般的条件下控制住此统计量的检验水平是一个悬而未决的问题。本文作者针对Chen & Qin (2010)的检验统计量，给出了统计量在不同的条件下所有可能的分布，提出了一种新的近似随机化检验方法，并给出其理论性质...

融合Fisher线性判别分析的多维特征融合情景感知推荐方法
多特征融合 Fisher线性判别分析 属性偏好 时间衰减 情景感知推荐
2017/8/22
针对采用单维特征建立用户的偏好模型所导致的推荐结果无法有效覆盖用户潜在偏好特征而影响推荐质量的问题,提出了一种基于Fisher线性判别分析的多维特征融合情景感知推荐方法。该方法建立了包含时间衰减度、属性偏好、偏好可影响程度等多维特征的偏好样本空间;采用特征融合、投影变换等方法,在最佳鉴别矢量空间基于Fisher判别准则融合用户的多维特征;采用拉格朗日乘子法求解最优投影方向,建立起多维特征优化的偏好...
基于Fisher信息对称的信息完全测量研究进展
量子测量 Fisher信息对称 量子态
2021/9/1
量子测量，作为提取信息的基本手段，是量子信息论中一个基本而重要的概念。量子态层析是指通过对多份同一未知量子态进行量子测量，再利用测量获取的信息对量子态进行估计，以确定真实量子态的过程。如何选择量子测量以有效地获取量子态的信息是量子态层析中的一个核心问题。理想的量子测量方案中涉及的量子测量算子要尽可能少，并且在实验中要易于实现。
