A hybrid anomaly detection method for high dimensional data [PDF]

open access: yesPeerJ Computer Science, 2023
Anomaly detection of high-dimensional data is a challenge because the sparsity of the data distribution caused by high dimensionality hardly provides rich information distinguishing anomalous instances from normal instances. To address this, this article

Telescope indexing for k-nearest neighbor search algorithms over high dimensional data & large data sets [PDF]

open access: yesScientific Reports
When k-Nearest-Neighbors ( $$k$$ -NN) was conceived more than 70 years ago, computation, as we use it now, would be hardly recognizable. Since then, technology has improved by orders of magnitude, including unprecedented connectivity.

Artificial Neural Network Model with Astrocyte-Driven Short-Term Memory

open access: yesBiomimetics, 2023
In this study, we introduce an innovative hybrid artificial neural network model incorporating astrocyte-driven short-term memory. The model combines a convolutional neural network with dynamic models of short-term synaptic plasticity and astrocytic ...

Information Encoding in Bursting Spiking Neural Network Modulated by Astrocytes

open access: yesEntropy, 2023
We investigated a mathematical model composed of a spiking neural network (SNN) interacting with astrocytes. We analysed how information content in the form of two-dimensional images can be represented by an SNN in the form of a spatiotemporal spiking ...

Deep forecasting of translational impact in medical research

open access: yesPatterns, 2022
Summary: The value of biomedical research—a $1.7 trillion annual investment—is ultimately determined by its downstream, real-world impact, whose predictability from simple citation metrics remains unquantified. Here we sought to determine the comparative

Features Clustering Around Latent Variables for High Dimensional Data [PDF]

open access: yesE3S Web of Conferences, 2021
Clustering of variables is the task of grouping similar variables into different groups. It may be useful in several situations such as dimensionality reduction, feature selection, and detect redundancies.

Discriminant methods for high dimensional data [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
The main purpose of discriminant analysis is to enable classification of new observations into one of g classes or populations. Discriminant methods suffer when applied to high dimensional data because the sample covariance matrix is singular.

High-Dimensional Separability for One- and Few-Shot Learning

open access: yesEntropy, 2021
This work is driven by a practical question: corrections of Artificial Intelligence (AI) errors. These corrections should be quick and non-iterative. To solve this problem without modification of a legacy AI system, we propose special ‘external’ devices,
