A Gradient Boosting-Based Feature Selection Framework for Predicting Student Performance
In educational data mining, accurate prediction of student performance is important for supporting timely intervention for at-risk students. However, educational datasets often include irrelevant or redundant features that could reduce the performance of prediction models. To tackle this issue, this...

Dynamical Behavior of a Second-Order Exponential-Type Fuzzy Difference Equation with Quadratic Term
The paper discusses the dynamical characteristics of solutions to a model with quadratic term. More precisely, an exponential-type fuzzy difference equation is proposed as follows $$ a_{n+1}=\frac{D+Pe^{-a_n}}{T+a^2_{n-1}},\ \ n=0,1,\cdots ,$$ here $D, P, T$ and $a_0, a_{-1}$ belong to positive fuz...

Analysis of a Pest-Natural Enemy Model with Time Delay in Impulsive Releasing Natural Enemy
Releasing amount of natural enemy generally depends on its population data, while impulsive releasing natural enemy usually brings about a time delay after the data is observed in the practical pest management. Therefore, it is very important for pest managers to assess the impact of the time delay...

Mathematical Study of Generalized Chemically Reactive NonNewtonain (Eyring-Powell) Material Capturing Varying Thermal Aspect Developing Cattaneo-Christov Concept
This study investigates the effects of a nonlinear stretched surface in a two-dimensional Modified Eyring-Powell liquid due to a double stratified chemical reactive flow of non-Fourier heat flux. We study the flux model which is the generalized form of Fourier's classical expression with thermal rel...

Fast and Robust Copy-Move Forgery Detection Using BRIEF, FAST, and SIFT Feature Matching
This paper presents a novel hybrid copy–move forgery detection method that combines the efficiency of FAST-BRIEF (for rapid keypoint detection and binary descriptors) with the robustness of SIFT (for scale- and rotation-invariant feature matching). The proposed framework employs g2NN matching for ac...
