The Study on the Text Classification Based on Graph Convolutional Network and BiLSTM

Applied Sciences, 2022
Graph Convolutional Neural Network (GCN) is widely used in text classification tasks. Furthermore, it has been effectively used to accomplish tasks that are thought to have a rich relational structure.

Generalized Reich-Moore R-matrix approximation

EPJ Web of Conferences, 2017
A conventional Reich-Moore approximation (RMA) of R-matrix is generalized into a manifestly unitary form by introducing a set of resonant capture channels treated explicitly in a generalized, reduced R-matrix.

Acoustic Signal Imaging Method Based on Synthetic Aperture Focusing and Full Matrix Capture

Highlights in Science, Engineering and Technology, 2022
In order to observe and understand the effect of acoustic signal detection more intuitively, imaging analysis is needed to obtain clearer detection results, and the detection situation is analyzed manually. The commonly used imaging method is B-scan imaging, which is also widely used in medical imaging.

Smooth Non-negative Low-Rank Graph Representation for Clustering [PDF]

Jisuanji kexue yu tansuo
The existing low-rank graph representation algorithms fail to capture the global representation structure of data accurately, and cannot make full use of the valid information of data to guide the construction of the representation graph, then the ...

Renormalization of the weak hadronic current in the nuclear medium [PDF]

, 2000
The renormalization of the weak charge-changing hadronic current as a function of the reaction energy release is studied at the nucleonic level. We have calculated the average quenching factors for each type of current (vector, axial vector and induced ...

Partition Functions of Matrix Models as the First Special Functions of String Theory I. Finite Size Hermitean 1-Matrix Model

, 2018
Even though matrix model partition functions do not exhaust the entire set of tau-functions relevant for string theory, they seem to be elementary building blocks for many others and they seem to properly capture the fundamental symplicial nature of ...

Warm dark matter sterile neutrinos in electron capture and beta decay spectra [PDF]

, 2016
We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture spectra, with a global perspective.
