However, advertisers usually have no sufficient knowledge to determine the optimal budget for each temporal slot, because there exist much uncertainty in search advertising markets. In this paper, we present a stochastic model for budget distribution over a series of sequential temporal slots under a finite time horizon, assuming that the best budget is a random variable. We study some properties and feasible solutions for our model, taking the best budget being characterized by either normal distribution or uniform distribution, respectively. Furthermore, we also make some experiments to evaluate our model and identify strategies with the real-world data collected from practical advertising campaigns. Experimental results show that a) our strategies outperform the baseline strategy that is commonly used in practice; b) the optimal budget is more likely to be normally distributed than uniformly distributed.","PeriodicalId":191638,"journal":{"name":"Proceedings of 2014 IEEE International Conference on Service Operations and Logistics, and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129221899","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}

Firstly, the fog-degraded image is segmented into blocks and low-rank decomposition is carried out for these blocks. Then the block with the minimal sparsity is selected for the local transfer function computation. And the global transfer function is derived from the super-resolution reconstruction based on the double-cubic interpolation. Finally, the enhanced image is obtained by deconvolution of the fog-degraded image and the global transfer function. Our proposed method is conducted based on the traffic videos obtained under the same view and angle. Moreover, our proposed method is compared with several state-of-the-art enhancement methods including notch filter, BM3D and Retinex Model. And the enhanced images are applied for vehicle tracking by the means of BWH mean shift. The experimental results illustrate that our proposed method can effectively eliminate the fog, preserve the useful information and achieve a better performance in terms of both information-entropy index and visual qualities.","PeriodicalId":191638,"journal":{"name":"Proceedings of 2014 IEEE International Conference on Service Operations and Logistics, and Informatics","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114121049","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}

Unlike the guaranteed display advertising, it utilizes programmatic instantaneous auction to price and sell ad inventory on a per-impression basis. RTB enbales advertisers to target audiences at demographic, psychographic or behavioral levels across a wide range of websites. In RTB markets, information about target audiences is usually disclosed to advertisers, while information about publishers (e.g. website ranking, advertising page) are typically not avaliable for advertisers, especially in real-time setting. This leads to a serious information asymmetry problem in RTB markets, which has significant influence on both advertisers' bidding strategies and publishers' revenues. In this paper, we study the information disclosure strategies of publishers in case when the disclosure may incur an extra cost. We address this information asymmetry problem by first formulating the RTB auction as an second-price sealed-bid game, then discussing equilibrium information disclosure strategies for publishers and also investigating advertisers' bidding strategies in the three information disclosure cases: all disclosed, non-disclosed, and partially disclosed. We find that non-disclosed and partially disclosed strategies may lead to an adverse selection effect, and high-quality publishers will be forced to quit the RTB markets.","PeriodicalId":191638,"journal":{"name":"Proceedings of 2014 IEEE International Conference on Service Operations and Logistics, and Informatics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114502638","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}
