Galaxy Evolution with Manifold Learning [PDF]

open access: yesEntropy
Matter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and ...

On Manifold Learning in Plato's Cave: Remarks on Manifold Learning and Physical Phenomena. [PDF]

open access: yesInt Conf Sampl Theory Appl SampTA, 2023
Many techniques in machine learning attempt explicitly or implicitly to infer a low-dimensional manifold structure of an underlying physical phenomenon from measurements without an explicit model of the phenomenon or the measurement apparatus. This paper presents a cautionary tale regarding the discrepancy between the geometry of measurements and the ...

Contagion Dynamics for Manifold Learning [PDF]

open access: yesFrontiers in Big Data, 2022
Contagion maps exploit activation times in threshold contagions to assign vectors in high-dimensional Euclidean space to the nodes of a network. A point cloud that is the image of a contagion map reflects both the structure underlying the network and the

Multi-Manifold Learning Fault Diagnosis Method Based on Adaptive Domain Selection and Maximum Manifold Edge [PDF]

open access: yesSensors
The vibration signal of rotating machinery is usually nonlinear and non-stationary, and the feature set has information redundancy. Therefore, a high-dimensional feature reduction method based on multi-manifold learning is proposed for rotating machinery

Comparison of manifold learning algorithms for identifying geochemical anomalies associated with copper mineralization [PDF]

open access: yesScientific Reports
The Baiyin district, situated within the northern Qilian orogenic belt, hosts the largest concentration of copper mineral resources in Gansu Province, Northwestern China. Geochemical anomaly patterns are crucial indicators for mineral exploration in this

Curvature-aware manifold learning [PDF]

open access: yesPattern Recognition, 2018
Traditional manifold learning algorithms assumed that the embedded manifold is globally or locally isometric to Euclidean space. Under this assumption, they divided manifold into a set of overlapping local patches which are locally isometric to linear subsets of Euclidean space. By analyzing the global or local isometry assumptions it can be shown that

The Impact of Supervised Manifold Learning on Structure Preserving and Classification Error: A Theoretical Study

open access: yesIEEE Access, 2021
In recent years, a variety of supervised manifold learning techniques have been proposed to outperform their unsupervised alternative versions in terms of classification accuracy and data structure capturing. Some dissimilarity measures have been used in

Neural excursions from manifold structure explain patterns of learning during human sensorimotor adaptation

open access: yeseLife, 2022
Humans vary greatly in their motor learning abilities, yet little is known about the neural mechanisms that underlie this variability. Recent neuroimaging and electrophysiological studies demonstrate that large-scale neural dynamics inhabit a low ...
