This paper presents a visual saliency detection method based on visual center offset. On the basis of pre-segmentation of the image, the significant areas of the image are extracted by combining the color contrast, color distribution and location characteristics. Using visual center transfer to simulate the visual transfer process of human observation, the image is analyzed at multiple scales. The results indicate that this approach is efficient because ROC curve and Precision-Recall performed well.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"88 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114027307","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}

Recently, the mainstream indoor positioning technologies include WiFi positioning and Bluetooth positioning. Various positioning methods have their own advantages and disadvantages due to their different positioning technologies. This paper proposes an indoor positioning method based on WiFi, Bluetooth and PDR fusion positioning. Firstly, WiFi positioning and Bluetooth positioning are achieved by improving the weighted centroid method. The WiFi and Bluetooth positioning are integrated, and the positioning result is integrated by weight adaptive constraint, which solves the problem of WiFi signal instability. The fusion positioning result and PDR positioning fusion are used to achieve fusion positioning through UKF, which solves the problem of large cumulative error in PDR positioning. The experiment proves that the WiFi, Bluetooth and PDR fusion positioning results are higher than the positioning accuracy of the individual positioning, which solves the problem that the WiFi positioning signal is unstable and the PDR cumulative error is large.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114920440","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}

Mobile edge computing (MEC) technology has been applied in vehicular networks (VNs) in recent years to cope with high vehicle mobility and network topology change. In this paper, we propose a group-partitioned video caching strategy algorithm (GPC) in VNs. The algorithm first partitions the video requesters and then employs the Lagrange function and Lambert function to solve the cache probability matrix as optimization variable. Correspondingly, we choose caching hit ratio and latency as cache performance evaluation metrics we take the revenue function as optimization objective, and aim to maximize the revenue value. Experimental results show that that the dual influence of video file size and cache size is a significant factor in the probability of caching. Our GPC algorithm outperforms other existing algorithms in the revenue.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115121995","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 actual total factor productivity of high-tech industries also fluctuates based on potential total factor productivity.

Traffic signal control is a basic tool for urban traffic management. Traditionally, the optimization of traffic light schedule and the prediction of traffic flows are studied separately. In this paper, we aim to combine these two techniques together and propose an urban traffic signal control system based on traffic flow prediction. The objective is to minimize the total number of blocked vehicles at all signalized intersections in the road network. Firstly, a new framework of urban traffic control system including both traffic flow forecasting and signal control optimization is proposed. Secondly, an adaptive traffic light scheduling strategy is designed to alleviate congestion. To validate the proposed system, experiments are performed on the real-world traffic data provided by the Aliyun Tianchi platform. The comparison results show that the proposed system and the signal control optimization strategy perform well.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128049416","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}

Policy-makers hope to Figure out population factors such as birth rate, size, and demographic structure to make policies that are conducive to longterm development of a country. Therefore, population projection has always been highly valued by many government workers and scholars. Compared with other traditional population projection methods, the weights and structure determination (WASD) neuronet does not require a vast knowledge of demography to achieve excellent performance. In this work, we substantiate the WASD neuronet by numerical experiments, which show the excellent performance of the WASD neuronet. Then, we make short-term and mid-term projections of Germany population and also make comparisons with other mainstream population projection methods. Finally, this paper presents a reasonable tendency of Germany population, i.e., declining slightly in near future but growing gently in one decade.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126350463","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}

Conventional NMF approaches cannot achieve a subspace made up of binary codes from the high-dimensional data space. To address the above-mentioned problem, we propose a method based on nonnegative matrix factorization to generate a low-dimensional subspace made up of binary codes from the high-dimensional data. The problem can be mathematically expressed as a 0-1 integer mixed optimization problem. For this purpose, We put forward a method based on discrete cyclic coordination descent to obtain a local optimal solution. Experiments show that our means can obtain the better clustering ability than conventional non-negative matrix factorization and its variant approaches.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114585837","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}
