Error Metrics for Learning Reliable Manifolds from Streaming Data

, 2017
Spectral dimensionality reduction is frequently used to identify low-dimensional structure in high-dimensional data. However, learning manifolds, especially from the streaming data, is computationally and memory expensive.

Translational genetic modelling of 3D craniofacial dysmorphology: elaborating the facial phenotype of neurodevelopmental disorders through the prism of schizophrenia [PDF]

, 2017
Purpose of Review: In the context of human developmental conditions, we review the conceptualisation of schizophrenia as a neurodevelopmental disorder, the status of craniofacial dysmorphology as a clinically accessible index of brain ...

Perturbation Theory for Generalized Procrustes Analysis

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1985
SUMMARY Perturbation theory for Procrustes statistics is developed when both configurations are subject to independent normal errors. The total sum of squares is shown to partition into sums of squares for translation, rotation/reflection and scaling, plus a residual. These results are extended to generalized Procrustes analysis.

The relationship between form and function of the carnivore mandible

The Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Procrustes analysis of a shape of pediatric supracondylar humerus fractures

Scientific Reports
Shape of supracondylar fracture of the humeral of pediatric patients is analysed with Procrustes method. XR-images of fractures are considered both in anterio-posterior (AP) view and in a lateral (L) view.

Construction of a time-scaled topology map of indoor WiFi access points for human mobility analysis from WiFi log

Geo-spatial Information Science
This study proposes a heuristic approach for constructing time-scaled topology maps of indoor WiFi networks using only WiFi log data, without relying on access point (AP) coordinates or signal strength measurements.

Changes in the Sensory Odor Profile during Chorizo Maturation and Their Relationship with Volatile Compound Patterns by Partial Least Square Regression (PLS)

Foods, 2023
Odor is one of the most important attributes to determine the overall acceptance of a product. The aim of this investigation is to evaluate the changes in the odor profile and the volatile compounds during thirty-three days of ripening to obtain the ...

Manifold Matching using Shortest-Path Distance and Joint Neighborhood Selection

, 2017
Matching datasets of multiple modalities has become an important task in data analysis. Existing methods often rely on the embedding and transformation of each single modality without utilizing any correspondence information, which often results in sub ...

The qualitative assessment of responsiveness to environmental challenge in horses and ponies. [PDF]

, 2008
The responsiveness of 10 horses and 10 ponies to environmental challenge (represented by an open field test) was assessed using a qualitative approach based on free choice profiling methodology (FCP), which gives observers complete freedom to choose ...

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.
