The differential geometry of perceptual similarity [PDF]

open access: green, 2017
Human similarity judgments are inconsistent with Euclidean, Hamming, Mahalanobis, and the majority of measures used in the extensive literatures on similarity and dissimilarity. From intrinsic properties of brain circuitry, we derive principles of perceptual metrics, showing their conformance to Riemannian geometry. As a demonstration of their utility,

Analysing Textbook Treatment of Similarity in Plane Geometry

open access: yesAnnales de Didactique et de Sciences Cognitives, 2019
This study presents a specific analysis of the treatment of the topic “similarity” by several college textbooks, in this case six Indonesian textbooks. The choice of this mathematical topic is justified by the fact that it requires in the activity of the

Log-Aesthetic Curves: Similarity Geometry, Integrable Discretization and Variational Principles [PDF]

open access: greenComputer Aided Geometric Design, 2018
In this paper, we consider a class of plane curves called log-aesthetic curves and their generalization which are used in computer aided geometric design. We consider these curves in the framework of the similarity geometry and characterize them as invariant curves under the integrable flow on plane curves which is governed by the Burgers equation.

Riemannian geometry and molecular similarity II: Kähler quantization [PDF]

open access: hybridProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
Shape similarity between molecules is a concept used by chemists for virtual screening, with the goal of reducing the cost and duration of drug discovery campaigns. This paper reports an entirely novel shape descriptor as an alternative to the previously described descriptors (Hall et al.

The Learning Trajectories of Similarity in Mathematics Curriculum: An Epistemological Analysis of Hong Kong Secondary Mathematics Textbooks in the Past Half Century

open access: yesMathematics, 2021
The topic of similarity plays an essential role in developing students’ deductive reasoning. However, knowing how to teach similarity and understanding how to incorporate deductive reasoning and proof along with plane geometry remain a challenge to both ...

THE EFFECT OF THE EUCLIDEAN GEOMETRY SHORT LEARNING PROGRAMME USING THE WORKED-OUT EXAMPLES TEACHING APPROACH ON MATHEMATICS TEACHERS' PERFORMANCE

open access: yesJOHME: Journal of Holistic Mathematics Education, 2022
The studies on the worked-out examples teaching approach (WOETA) have been investigated globally and in South Africa, showing gains in learners' performance. This study reports on the Euclidean geometry short learning programme (EGSLP), which used worked-

Measure of Similarity between GMMs Based on Geometry-Aware Dimensionality Reduction

open access: yesMathematics, 2022
Gaussian Mixture Models (GMMs) are used in many traditional expert systems and modern artificial intelligence tasks such as automatic speech recognition, image recognition and retrieval, pattern recognition, speaker recognition and verification ...
