چکیده

Abstract Technological advances have significantly affected education, leading to the creation of online learning platforms such as virtual environments and massive open courses. While these offer a variety features, none them incorporates module that accurately predicts students’ academic performance commitment. Consequently, it is crucial design machine (ML) methods predict student identify at-risk students early possible. Graph representations data provide new insights into this area. This paper describes simple but highly accurate technique for converting tabulated graphs. We employ distance measures (Euclidean cosine) calculate similarities between construct graph. extract graph topological features ( GF ) enhance our data. allows us capture structural correlations among gain deeper than isolated analysis. The initial dataset DS can be used alone or jointly improve predictive power ML method. proposed method tested on an educational returns superior results. use compared with $$DS + GF$$ D S + G F in classification three classes: “failed”,“at risk”, “good”. area under receiver operating characteristic curve (AUC) reaches 0.948 using , 0.964 . accuracy case varies from 84.5 87.3%. Adding improves by 2.019% terms AUC 3.261% accuracy. Moreover, incorporating through convolutional network (GCN), prediction enhanced 0.5% 0.9% cosine matrix. With Euclidean matrix, adding GCN 3.7% 2.4%. By embedding models, identified 87.4% 0.97 AUC. solution provides tool detection students. will benefit universities their performance, improving both effectiveness reputation.

Learning Graph Topological Features via GAN

Inspired by the generation power of generative adversarial networks (GANs) in image domains, we introduce a novel hierarchical architecture for learning characteristic topological features from a single arbitrary input graph via GANs. The hierarchical architecture consisting of multiple GANs preserves both local and global topological features and automatically partitions the input graph into r...

Introducing a method for extracting features from facial images based on applying transformations to features obtained from convolutional neural networks

In pattern recognition, features are denoting some measurable characteristics of an observed phenomenon and feature extraction is the procedure of measuring these characteristics. A set of features can be expressed by a feature vector which is used as the input data of a system. An efficient feature extraction method can improve the performance of a machine learning system such as face recognit...
