Learning Picture Languages Using Dimensional Reduction

open access: yesInteligencia Artificial, 2023
One-dimensional (string) formal languages and their learning have been studied in considerable depth. However, the knowledge of their two-dimensional (picture) counterpart, which retains similar importance, is lacking.

Dimensional Reduction and Hadronic Processes

open access: yes, 2008
We consider the application of regularization by dimensional reduction to NLO corrections of hadronic processes. The general collinear singularity structure is discussed, the origin of the regularization-scheme dependence is identified and transition ...

Dynamics of dimensional reduction

open access: yesPhysics Letters B, 1980
In d-dimensional unified theories that, along with gravity, contain an antisymmetric tensor field of rank s-1, preferential compactification of d-s or of s space-like dimensions is found to occur. This is the case in 11-dimensional supergravity where s = 4.

Mixing Autoencoder With Classifier: Conceptual Data Visualization

open access: yesIEEE Access, 2020
In this paper, a neural network that is able to form a low-dimensional topological hidden representation is explained. The neural network can be trained as an autoencoder, as a classifier or as a mixture of both and produces a different low-dimensional ...

Shape-Informed Dimensional Reduction in Airfoil/Hydrofoil Modeling

open access: yesJournal of Marine Science and Engineering, 2023
Parametric models have been widely used in pertinent literature for reconstructing, modifying and representing a wide range of airfoil and/or hydrofoil profile geometries.

Limitations on quantum dimensionality reduction [PDF]

open access: yesInternational Journal of Quantum Information, 2011
The Johnson–Lindenstrauss Lemma is a classic result which implies that any set of n real vectors can be compressed to O( log n) dimensions while only distorting pairwise Euclidean distances by a constant factor. Here we consider potential extensions of this result to the compression of quantum states. We show that, by contrast with the classical case,

Binary Codes Based on Non-Negative Matrix Factorization for Clustering and Retrieval

open access: yesIEEE Access, 2020
Traditional non-negative matrix factorization methods cannot learn the subspace from the high-dimensional data space composed of binary codes. One hopes to discover a compact parts-based representation composed of binary codes, which can uncover the ...

Visualizing the quality of dimensionality reduction [PDF]

open access: yesNeurocomputing, 2013
The growing number of dimensionality reduction methods available for data visualization has recently inspired the development of formal measures to evaluate the resulting low-dimensional representation independently from the methods' inherent criteria. Many evaluation measures can be summarized based on the co-ranking matrix.

Dimensional Reduction of Cobordism and K-theory

open access: yesJournal of High Energy Physics, 2023
It has been proposed that cobordism and K-theory groups, which can be mathematically related in certain cases, are physically associated to generalised higher-form symmetries.
