Orthogonality and Dimensionality [PDF]
Axioms, 2013 In this article, we present what we believe to be a simple way to motivate the use of Hilbert spaces in quantum mechanics. To achieve this, we study the way the notion of dimension can, at a very primitive level, be defined as the cardinality of a maximal collection of mutually orthogonal elements (which, for instance, can be seen as spatial directions)

The Intrinsic Dimensionality of Attractiveness: A Study in Face Profiles [PDF]
, 2012 The study of human attractiveness with pattern analysis techniques is an emerging research field. One still largely unresolved problem is which are the facial features relevant to attractiveness, how they combine together, and the number of independent ...

Dimensionality reduction for probabilistic movement primitives [PDF]
, 2014 Humans as well as humanoid robots can use a large number of degrees of freedom to solve very complex motor tasks. The high-dimensionality of these motor tasks adds difficulties to the control problem and machine learning algorithms.

New approaches on dimensionality reduction in hyperspectral images for classification purposes [PDF]
, 2012 This paper presents a quasi-unsupervised methodology to detect endmembers within an hyperspectral scene and to derive a pixel-wise classification on its basis.

Ultrafast Charge Transfer Cascade in a Mixed-Dimensionality Nanoscale Trilayer [PDF]
, 2023 Innovation in optoelectronic semiconductor devices is driven by a fundamental understanding of how to move charges and/or excitons (electron-hole pairs) in specified directions for doing useful work, e.g. for making fuels or electricity.

Problem dimensionality reduction in design of optimal IIR filters [PDF]
, 2002 A typical design of a digital IIR filter that is optimal in the sense of the weighted least squares criterion is performed by using a numerical optimisation procedure capable of searching for local minima of highly non-linear functions of vector ...

Dimensionality Reduction by Weighted Connections between Neighborhoods [PDF]
, 2014 Dimensionality reduction is the transformation of high-dimensional data into a meaningful representation of reduced dimensionality. This paper introduces a dimensionality reduction technique by weighted connections between neighborhoods to improve K ...
