EGFAFS: A Novel Feature Selection Algorithm Based on Explosion Gravitation Field Algorithm

open access: yesEntropy, 2022
Feature selection (FS) is a vital step in data mining and machine learning, especially for analyzing the data in high-dimensional feature space. Gene expression data usually consist of a few samples characterized by high-dimensional feature space.

$d$-dimensional SYK, AdS Loops, and $6j$ Symbols [PDF]

open access: yes, 2019
We study the $6j$ symbol for the conformal group, and its appearance in three seemingly unrelated contexts: the SYK model, conformal representation theory, and perturbative amplitudes in AdS.

Symbolic Behavior in Regular Classrooms: A Specification of Symbolic and Non-Symbolic Behavior [PDF]

open access: yesFrontiers in Psychology, 2011
Students' capabilities to use symbolic information in classroom setting could be expected to influence their possibilities to be active and participating. The development of strategies for teachers to compensate for reduced capability need specific operational definition of symbolic behavior.

Overlapping Community Detection Based on Membership Degree Propagation

open access: yesEntropy, 2020
A community in a complex network refers to a group of nodes that are densely connected internally but with only sparse connections to the outside. Overlapping community structures are ubiquitous in real-world networks, where each node belongs to at least

LncMirNet: Predicting LncRNA–miRNA Interaction Based on Deep Learning of Ribonucleic Acid Sequences

open access: yesMolecules, 2020
Long non-coding RNA (LncRNA) and microRNA (miRNA) are both non-coding RNAs that play significant regulatory roles in many life processes. There is cumulating evidence showing that the interaction patterns between lncRNAs and miRNAs are highly related to ...
