The model completes self-supervised learning through two positive-and-negative case-based constrastive learning tasks clotfilling prediction and subsequence prediction. Firstly, the algorithm masks a individual item and subsequence of the user interaction respectively according to the corresponding task requirements, and then predicts the missing items through the encoding layer and the self-attention layer. During the process, the model automatically constructs the positive and negative examples of the prediction results, and completes the training according to the constrastive learning loss function corresponding to the task, so as to learn the correct semantic feature representation and space vector coding. Secondly, the model utilizes the trained upstream item coding for the downstream prediction. Finally, the model can obtain user-satisfactory recommended results. By comparison of experimental results on Beauty, Toys and LastFM, the CLSRec works better on multiple metrics.","PeriodicalId":345703,"journal":{"name":"2022 International Symposium on Advances in Informatics, Electronics and Education (ISAIEE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126666148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of the single traditional experimental teaching mode and students' passive coping, this paper proposes an experimental teaching method based on the combination of virtual reality and the integration of science and education. First of all, it introduces the importance of the combination of virtual reality and the integration of science and education to the development of students; Secondly, taking the electrical experimental teaching as an example, on the basis of making full use of the existing experimental equipment, build a new experimental platform to discuss the experimental teaching methods; Finally, through students' experimental teaching cases, it shows the usefulness of the experimental teaching method, which has a good role in promoting the cultivation of students' innovative ability.

Especially affected by the COVID-19 epidemic, online learning has become a very effective learning means. However, a large number of learning platforms and massive online teaching resources have the following three problems: 1) The quality of these courses is uneven and the evaluation standards are different; 2) There are so many similar courses that it is difficult for learners to distinguish them; 3) These classes are lack of unity and integration, and it is hard to recommend any hierarchical, coherent and systematic course resources to learners. Therefore, a recommendation model based on TF-IDF algorithm is designed to extract personalized-featured courses, use the nearest neighbor similarity to cluster the similarity of similar courses, and conduct the featured portrait of learners to realize online courses recommendation. Combined with the model design, this paper presents a tag-based online course resource recommendation system, which can fully explore learners' explicit and implicit preferences according to course tags, and recommend satisfactory MOOC resources for them with good application value.","PeriodicalId":345703,"journal":{"name":"2022 International Symposium on Advances in Informatics, Electronics and Education (ISAIEE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122973161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
