Protest symbols [PDF]

open access: yesCurrent Opinion in Psychology, 2020
Recent research on social movements have shown the significant role protest symbols play in mobilizing action and constructing a shared identity for a group pressing for social change. The present article gives an overview of crowd and social movement theories that focus on how symbols form and maintain groups.

3D ROC Histogram: A New ROC Analysis Tool Incorporating Information on Instances

open access: yesIEEE Access, 2019
While Receiver Operator Characteristic (ROC) curves have been a standard tool in the design and evaluation of binary classification problems, they have sometimes been blamed for ignoring some vital information in the evaluation process, such as predicted

A Purely Symbol-Based Precoded and LDPC-Coded Iterative-Detection Assisted Sphere-Packing Modulated Space-Time Coding Scheme [PDF]

open access: yes, 2006
In this contribution, we propose a purely symbol-based LDPC-coded scheme based on a Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBCSP).

Overhead Analysis and Evaluation of Approaches to Host-Based Bot Detection

open access: yesInternational Journal of Distributed Sensor Networks, 2015
Host-based bot detection approaches discover malicious bot processes by signature comparison or behavior analysis. Existing approaches have low performance which has become a bottleneck blocking its wider deployment.

A Novel Multi-Thread Parallel Constraint Propagation Scheme

open access: yesIEEE Access, 2019
Constraint Programming (CP) is an efficient technique for solving combinatorial (optimization) problems. In modern constraint solver, a CP Model is defined over reversible variables that take values in domains and propagators which filter the domains of ...

On the optimality of symbol-by-symbol filtering and denoising [PDF]

open access: yesIEEE Transactions on Information Theory, 2004
This paper describes the optimality of symbol by symbol filtering and denoising and considers the problem of optimally recovering a discrete-time valued stochastic process from a noisy observation process. For binary Markov input process singlet filtering and denoising are optimal.

An Efficient v-Minimum Absolute Deviation Distribution Regression Machine

open access: yesIEEE Access, 2020
Support Vector Regression (SVR) and its variants are widely used regression algorithms, and they have demonstrated high generalization ability. This research proposes a new SVR-based regressor: v-minimum absolute deviation distribution regression (v-MADR)

A multi-task positive-unlabeled learning framework to predict secreted proteins in human body fluids

open access: yesComplex & Intelligent Systems, 2023
Body fluid biomarkers are very important, because they can be detected in a non-invasive or minimally invasive way. The discovery of secreted proteins in human body fluids is an essential step toward proteomic biomarker identification for human diseases.

DenSec: Secreted Protein Prediction in Cerebrospinal Fluid Based on DenseNet and Transformer

open access: yesMathematics, 2022
Cerebrospinal fluid (CSF) exists in the surrounding spaces of mammalian central nervous systems (CNS); therefore, there are numerous potential protein biomarkers associated with CNS disease in CSF.
