How human and nature shake hands: The role of no-conspiracy in physical theories

No-conspiracy is the requirement that measurement settings should be probabilistically independent of the elements of reality responsible for the measurement outcomes. In this paper we investigate what role no-conspiracy generally plays in a physical theory; how it influences the semantical role of the event types of the theory; and how it relates to such other concepts as separability, compatibility, causality, locality and contextuality.

基于局部约束字典学习的非线性降维人脸识别

针对现有的非线性降维(NLDR)算法复杂度高而不能很好地处理现实世界大规模数据集的问题,提出了基于局部约束字典学习的非线性降维(LCDL-NLDR)方法。首先通过一些潜在的标志点重构极小的内在流形,并将训练数据和未知数据自然地嵌入到内部流形中;然后利用局部约束字典学习(LCDL)算法在非线性流形中学习由标志点组成的紧密原子集;最后利用最近邻分类器完成人脸的识别。在扩展的YaleB及CMU PIE两大人脸数据库上的实验验证了所提方法的有效性及鲁棒性,通过与几种先进的字典学习算法比较表明,所提算法提高了嵌入质量,取得了更高的识别率,同时也大大地降低了NLDR算法的复杂度。     

基于特征融合的KLPCCA及其在人脸识别中的应用

对发掘人脸图像中的高维非线性结构,将加核及典型相关分析两种思想同时引入局部保留投影算法中,提出了一种新的基于核的局部保持典型相关分析（Kemel base Locality Preserving Canonical Correction Analvsis,KLPCCA）非线性子空间人脸识别算法并给出了其推导过程。算法首先利用核的方法提取人脸图像中的非线性信息,然后通过局部保持投影算法做一线性映射,从而更简单准确的进行人脸识别。在ORL上的试验证明了该文所提算法的有效性。     

Squaring the circle: Gleb Wataghin and the prehistory of quantum gravity

The early history of the attempts to unify quantum theory with the general theory of relativity is depicted through the work of the Italian physicist Gleb Wataghin, who, in the context of quantum electrodynamics, has anticipated some of the ideas that the quantum gravity community is entertaining today.     

基于改进局部保持映射的图像特征提取算法

针对目前局部保持映射算法(LPP)因忽略类标识信息而造成的计算效率问题,提出了基于类标识信息的监督局部保持映射算法,并将其用于图像特征提取中,该算法通过用类标识信息指导最邻近图构造过程来提高算法的效率,仿真实验的结果表明,该方法可以有效提高传统局部保持映射算法的运算效率,提高图像特征提取性能.     

用于人脸识别的半监督优化局部保持投影

未充分利用大量未标注样本的非监督信息是监督的、优化的局部保持投影(简称SOLPP)在人脸识别应用中的主要问题。为此提出一种用于人脸识别的半监督的优化的局部保持投影(SSOLPP)。该算法在SOLPP的基础上,通过加权平衡参数融合了未监督的主成分析(PCA)降维算法,使得投影后的数据保持了高维数据中的未标注样本的、全局的散布结构信息和监督的优化局部结构信息。在YaleB和AR人脸数据集上的实验验证了所提算法的有效性。     

地域归真的语境编织：石碇小镇历史空间参与设计的修补式实践①

面对着二战后一系列的现代性冲击,诸如石碇这般位于“全球都会区域”外围的历史地域正遭逢了地方魅力快速沦丧的严峻挑战。华梵大学建筑学系联合各界力量秉持着将规划设计视为一种“写本实践”的体认,既藉由涵盖自然、历史与社会等面向的参与式设计带入阅者语境以掌握“石碇性”,又透过重构地域脉络的修补式实践赋予石碇以具有深刻义蕴的魅力,奉行了在深度愿景指导下强调“语境编织”的异质空间规划设计方法论,动员了营造手法以重构功能并点化象征,希望让小镇能逐渐脱离地方庸俗化的困境,并迈向地域归真的坦途。对此实践作一回顾及初步检讨,期待能为海峡两岸同样受到现代性肆虐的地域空间提供可资参考的营造之途。     

基于局部保持投影和RBF神经网络的DOA估计

提出了一种有效的降维构建方法改善来波到达角（DOA）估计的性能。该方法利用局部保持投影（LPP）对DOA估计用的神经网络的训练样本进行降维,以降低神经网络的复杂度,加快神经网络的训练过程。与常用的协方差矩阵上三角特征相比,在不损失有效方位信息的基础上,可以使特征维数极大地降低。数值实验表明,基于局部保持投影和神经网络的方法具有良好的估计精度和效率,同时对噪声也有较强的适应能力,能够很好地满足波达方向估计实时性的要求。     

On the “negative utility” of Ernst Cassirer׳s philosophy of physics: An application to the EPR argument

This paper tries to reconstruct Ernst Cassirer's potential reception of the EPR argument, as exposed by Einstein in his letter to Cassirer of March 1937. It is shown that, in conformity with his transcendental epistemology taking the conditions of accessibility as constitutive of the quantum object, Cassirer would probably have rejected the argument. Indeed, Cassirer would probably not have subscribed to its separability/local causality presupposition (which goes against his interpretation of the quantum formalism as a self-sufficient condition constitutive of the quantum object, without any reliance on spatial intuition), nor to its completeness requirement (as his partial endorsement of Bohr's complementarity, and his rejection of the Kantian "idea of complete determination", illustrate). By rejecting both of its premises, Cassirer's philosophy of physics thus enables to escape the EPR dilemma, and exhibits what, in Kantian terms, might be called a "negative utility" with respect to physical science. A further investigation of the anti-reductionist utility of Cassirer's systematic philosophy with respect to physics and other "symbolic forms" is finally suggested.
