However, blurred clustering is inevitable due to the lack of overall clustering environment information, which means that no significant differences were observed between clusters. To address this issue, we propose a memory enhanced model for deep clustering with reinforcement strategy, where a Memory Cell is introduced as a storage unit for surrounding imformation. Specifically, the whole process of the model is divided into three parts. Firstly, the original high-dimensional image data is mapped to latent feature space thorugh the pre-training process, and the latent feature representation is obtained and stored in Memory Cell. Secondly, the traditional K-means algorithm is applied to initialize the clustering center on the latent representation. Finally, the reward regression strategy in reinforcement learning based on the Bernoulli distribution is adopted to fine-tune the results. ACC, ARI and NMI as evaluation metrics, the proposed model shows its competitiveness on MNIST and Fashion-MNIST dataset against recent state-of-art models.","PeriodicalId":338866,"journal":{"name":"The 2nd European Symposium on Computer and Communications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125694358","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}
