SFA: Small Faces Attention Face Detector

IEEE Access, 2019
Tremendous strides have been made in face detection thanks to convolutional neural network. However, the performance of previous face detectors deteriorates dramatically as the face scale shrinks.

Understanding socialbot behavior on end hosts

International Journal of Distributed Sensor Networks, 2017
Server-side socialbot detection approaches can identify malicious accounts and spams in online social networks. However, they cannot detect socialbot processes, residing on user hosts, which control these accounts. Therefore, new approaches are needed to

Detection and Independent Validation of Model-Based Quantitative Transcriptional Regulation Relationships Altered in Lung Cancers

Frontiers in Bioengineering and Biotechnology, 2020
Differential expressions of genes are widely evaluated for the diagnosis and prognosis correlations with diseases. But limited studies investigate how transcriptional regulations are quantitatively altered in diseases.

MuscNet, a Weighted Voting Model of Multi-Source Connectivity Networks to Predict Mild Cognitive Impairment Using Resting-State Functional MRI

IEEE Access, 2020
The neurological disorder mild cognitive impairment (MCI) demonstrates minor impacts on the patient's daily activities and may be ignored as the status of normal aging.

The unpolarized and polarized single-mass three-loop heavy flavor operator matrix elements A gg,Q and ∆A gg,Q

Journal of High Energy Physics, 2022
We calculate the gluonic massive operator matrix elements in the unpolarized and polarized cases, A gg,Q (x, μ 2) and ∆A gg,Q (x, μ 2), at three-loop order for a single mass.

Symbolic Computation Software Composability [PDF]

, 2008
We present three examples of the composition of Computer Algebra Systems to illustrate the progress on a composability infrastructure as part of the SCIEnce (Symbolic Computation Infrastructure for Europe) project1. One of the major results of the project so far is an OpenMath based protocol called SCSCP (Symbolic Computation Software Composability ...

Computations for symbolic substitutions [PDF]

, 2017
We provide a survey of results from symbolic dynamics and algebraic topology relating to Grout, a new user-friendly program developed to calculate combinatorial properties and topological invariants of a large class of symbolic substitutions. We study their subshifts (and related spaces) with an emphasis on examples of computations.

Constrained Consistency Modeling for Attributed Network Embedding

IEEE Access, 2019
Network embedding has emerged as a fundamental approach to network analysis tasks. Its main purpose is to learn a suitable mapping function to convert nodes in networks into a low-dimensional representations.

The OCS-SVM: An Objective-Cost-Sensitive SVM With Sample-Based Misclassification Cost Invariance

IEEE Access, 2019
Studies on the traditional support vector machine (SVM) implicitly assume that the costs of different types of mistakes are the same and minimize the error rate.
