UGRWO-Sampling for COVID-19 dataset: A modified random walk under-sampling approach based on graphs to imbalanced data classification
Saeideh Roshanfekr, Shahriar Esmaeili, Hassan Ataeian +1
This paper proposes a new RWO-Sampling (Random Walk Over-Sampling) based on graphs for imbalanced datasets. In this method, two schemes based on under-sampling and over-sampling me…
Weighted second-order cone programming twin support vector machine for imbalanced data classification
Saeideh Roshanfekr, Shahriar Esmaeili, Hassan Ataeian +1
We propose a method of using a Weighted second-order cone programming twin support vector machine (WSOCP-TWSVM) for imbalanced data classification. This method constructs a graph b…
QLMC-HD: Quasi Large Margin Classifier based on Hyperdisk
Hassan Ataeian, Shahriar Esmaeili, Saeideh Roshanfekr +3
In the area of data classification, the different classifiers have been developed by their own strengths and weaknesses. Among these classifiers, we propose a method that is based…
Extraction of Active Regions and Coronal Holes from EUV Images Using the Unsupervised Segmentation Method in the Bayesian Framework
Saeid Arish, Mohsen Javaherian, Hossein Safari +1
The solar corona is the origin of very dynamic events that are mostly produced in active regions (AR) and coronal holes (CH). The exact location of these large-scale features can b…
An efficient parallel algorithm for computing determinant of non square matrices
Neda Abdollahi, Mohammad Jafari, Morteza Bayat +2
One of the most significant challenges in Computing Determinant of Rectangular Matrices is high time complexity of its algorithm. Among all definitions of determinant of rectangula…
Automatic Method for Identifying Photospheric Bright Points and Granules Observed by Sunrise
Mohsen Javaherian, Hossein Safari, Ali Amiri +1
In this study, we propose methods for the automatic detection of photospheric features (bright points and granules) from ultra-violet (UV) radiation, using a feature-based classifi…
