Evaluating English Language Teaching Quality in Classrooms Using OLAP and SVM Algorithms

Abstract

Currently, the existing techniques of evaluating quality of teaching quality colleges and universities within China are based on classical and statistical methods. However, these methods are unable to accurately reflect the real and actual evaluation of teaching quality. Furthermore, in this era of computerization, education has also revamped itself and is not limited to the conventional lecturing approach. Nowadays, English has become one of the most important skills for foreigners as countries move toward internationalization resulting in a huge amount of data being collected in educational databases, which remains unused. Powerful tools are required to improve the quality of English teaching and reap the benefits of big data generated in classrooms. In this paper, online analytical processing (OLAP) in combination with a support vector machine (SVM) classification algorithm is adopted, and then the algorithm constructs the linear optimal decision function in the feature space. Through the training of sample data by the SVM algorithm, relatively high-quality classification results can be obtained on the target object, especially for high-dimensional cases. The proposed approach has an extremely efficient application value. Compared with the existing methods, the error of evaluation results can be greatly improved, which leads to further improvement of accuracy in terms of evaluation results.

Classroom Behaviour of Talent Cultivation in Colleges and Universities Supported by Deep Learning Technology

“…This analysis presents the implementation of deep learning algorithms in basketball strategies and the basis of deep learning. Zhang et al [23] developed the linear optimum classification model in the feature space using online analytical processing (OLAP) in conjunction with a support vector machine (SVM) classification algorithm. Sui et al [24] examined the overabundance of graduates in a given time due to increased enrolment in different colleges and universities, as well as the sociological phenomena of short social positions.…”

Educational Practice Based on the Integration of Support Vector Machines and English Curricula

“…Z. Zhang et al (2022) used the OVR method, OVO method, and improved BT-SVM algorithm in their research and conducted 10 experiments in five selected data sets, respectively. The accuracy of the improved algorithm is two percentage points higher than that of the OVR and OVO algorithms in the best case.…”

Big data-based output-oriented teaching competency development for mathematics teacher trainees

“…This is when the optimal solution is 𝛼 * = (𝛼 1 * , 𝛼 2 * , … , 𝛼 𝑙 * ) 𝑇 , usually for most of the sample points 𝛼 𝑖 = 0, and only a very small fraction of the sample 𝑥 𝑖 corresponds to a non-zero 𝛼 𝑖 * . The sample points corresponding to 𝛼 𝑖 * ≠ 0 are called support vectors [17].…”
