Orthogonal Procrustes Analysis for Dictionary Learning in Sparse Linear Representation. [PDF]
PLoS One, 2017 In the sparse representation model, the design of overcomplete dictionaries plays a key role for the effectiveness and applicability in different domains. Recent research has produced several dictionary learning approaches, being proven that dictionaries

Deep Learning and Procrustes Analysis for Early Dysgraphia Risk Detection with a Tablet Application. [PDF]
Life (Basel), 2023 Dysgraphia is a neurodevelopmental disorder specific to handwriting. Classical diagnosis is based on the evaluation of speed and quality of the final handwritten text: it is therefore delayed as it is conducted only when handwriting is mastered, in ...

On Procrustes Analysis in Hyperbolic Space [PDF]
IEEE Signal Processing Letters, 2021 Congruent Procrustes analysis aims to find the best matching between two point sets through rotation, reflection and translation. We formulate the Procrustes problem for hyperbolic spaces, review the canonical definition of the center of point sets, and give a closed form solution for the optimal isometry for noise-free measurements.

Procrustes Analysis for High-Dimensional Data. [PDF]
Psychometrika, 2022 Abstract The Procrustes-based perturbation model (Goodall in J R Stat Soc Ser B Methodol 53(2):285–321, 1991) allows minimization of the Frobenius distance between matrices by similarity transformation. However, it suffers from non-identifiability, critical interpretation of the transformed matrices, and inapplicability in high ...

Hyperspectral Image-Based Variety Classification of Waxy Maize Seeds by the t-SNE Model and Procrustes Analysis. [PDF]
Sensors (Basel), 2018 Variety classification is an important step in seed quality testing. This study introduces t-distributed stochastic neighbourhood embedding (t-SNE), a manifold learning algorithm, into the field of hyperspectral imaging (HSI) and proposes a method for ...

A novel method for 3D face symmetry reference plane based on weighted Procrustes analysis algorithm. [PDF]
BMC Oral Health, 2020 Background We aimed to establish a novel method, using the weighted Procrustes analysis (WPA) algorithm, which assigns weight to facial anatomical landmarks, to construct a three-dimensional facial symmetry reference plane (SRP) for mandibular deviation ...

Using Generalized Procrustes Analysis for Evaluation of Sensory Characteristic Data of Lamb Meat
Turkish Journal of Agriculture: Food Science and Technology, 2019 Generalized Procrustes Analysis (GPA) is a multivariate statistic method that is used at the evaluation of sensory analyses in the food industry. GPA provides benefit in terms of decreasing the difference between the panellists and bringing the data ...

Generalized Procrustes Analysis
Psychometrika, 1975 Suppose Pi(i) (i = 1, 2, ..., m, j = 1, 2, ..., n) give the locations of mn points in p-dimensional space. Collectively these may be regarded as m configurations, or scalings, each of n points in p-dimensions. The problem is investigated of translating, rotating, reflecting and scaling the m configurations to minimize the goodness-of-fit criterion Σi ...
