In this paper we have collected a database of The MNIST DATABASE, we proposed nearest neighbor search in the database and can get a good result in an acceptable time. The experimental results show that our data structure is up to about 10 times faster than ordinary Locality-Sensitive Hashing when working on a database of 60000 samples. At the same time, the accuracy rate and recall rate are higher than earlier algorithms.","PeriodicalId":311451,"journal":{"name":"2015 10th International Conference on Computer Science & Education (ICCSE)","volume":"348 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115412284","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}

With the popularity of mobile intelligent terminal, the Wi-Fi based wireless transmission technology could make it easy to use the common Android mobile phone or iPad as the endoscopic receiver.

Interested students can use the ISES remote laboratory for experimenting as a unique educational tool to understand the desired phenomena. This is particularly useful for distant students, whom are often not enabled frequent experimental and laboratory courses. The main reason to deal with this issue is the absence of any detection technique of faults and any diagnostic system to help improving the administration. The diagnostic system is designed for those responsible for the ISES remote laboratory hardware functioning. The first chapter, the state of the art, aims to introduce the ISES remote laboratory concept. The next chapter presents the Runtime modules detection component used for the identifying and detecting connected ISES hardware modules by using two bit triplets and masks. The second part of this chapter describes the Rule-based methods exploiting heuristics to detect faults in these modules. The final chapter summarizes all the benefits brought for involved administrators of the ISES remote laboratories.","PeriodicalId":311451,"journal":{"name":"2015 10th International Conference on Computer Science & Education (ICCSE)","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132479469","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}
