Network security has been seriously threatened to a certain extent, and network security technology has also attracted more and more attention from the public. As a security protection technology for actively monitoring network data, intrusion detection technology effectively compensates for the defects of traditional security protection technologies such as firewalls and data encryption, and has become an important research field in network security. Based on this, it is very important to design the security mechanism of the system to prevent unauthorized access to system resources and data. This paper uses a DBSCAN algorithm for anomaly detection clustering algorithm. Algorithms that can be used for massive data processing have become a research hotspot in anomaly detection. Normal behavior profiles are formed on audit records and adjusted in time as program behavior changes. Experimental results show that, compared with other algorithms, anomaly detection based on the DBSCAN algorithm can improve the detection rate of the data set, and significantly improve the accuracy of anomaly detection.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124075080","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}

However, there are still some bottlenecks in the existing cross-modal audio and image retrieval methods: 1. How to establish an effective correlation between voice and image to improve the retrieval accuracy; 2. How to reduce the storage of large-scale cross-modal data and accelerate the retrieval speed. In order to solve the above problems, this paper proposes a new deep collaborative hashing cross modal audio image retrieval method (ssch), which can generate hash codes with low storage capacity and fast retrieval. In particular, ssch can use the similarity of deep features to establish the semantic relationship between speech and image, and ssch method can fuse image feature vector and audio feature vector to learn hash code cooperatively. In addition, for hash code learning, our method tries to maintain the semantic similarity of binary code and reduce the information loss generated by binary code. Experimental results show that ssch algorithm has better retrieval performance than other advanced cross modal retrieval methods.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122053586","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}

This paper studies the Unbalanced Connected Subgraphs problem, referred to as UBCS problem. Given a graph with nodes belonging to different categories, the objective of UBCS problem is to find the maximum connected subgraph in which the number and proportion of nodes in certain categories can meet given requirements, respectively. This problem has many real-world applications, for example, to find the largest subgraph of a social network in which the proportion of people who likes a specific product is not less than a given value. This paper introduces the formal definition of UBCS problem, studies its computational complexity and proves that it is NP-hard in planar graphs. A mixed integer programming model based on network flow is proposed to formulate this problem. Moreover, a simple and fast heuristic algorithm is designed to solve UBCS problem in large-scale sparse graphs. Through numerical experiments, the advantages and disadvantages of the heuristic are verified and compared with the optimization solver IBM ILOG CPLXE.","PeriodicalId":178054,"journal":{"name":"2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128569705","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}

The increase of TBOX can improve frequency characteristics. However, the increase of TBOX will affect the stability of the device.
