On the spark platform, users can adjust parameter configurations according to different job requirements and specific applications to optimize performance. This leads to a problem that we can’t ignore, Spark already has more than 180 parameters, and its huge combination of parameters means that we can’t rely on manual tuning to grasp the impact of all parameters on performance. In order to solve the problem of relying heavily on expert experience and manual operation, we propose Otterman, a parameters optimization approach based on the combination of Simulated Annealing algorithm and Least Squares method, which can help us dynamically adjust parameters according to job types to obtain optimal configuration to improve performance. Simulated Annealing can find the optimal solution, but has poor convergence. We make use of the Least Squares method to effectively improve the speed at which the former converges to the optimal solution. Otterman is simple and easy to perform, with no additional cost. The effectiveness of the approach is verified by experiments, the results show that Otterman’s average performance has increased by 30% compared to the default parameters configuration, with an accuracy of about 68%.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125150936","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}

Most of the existing 3D audio technologies reconstruct the original sound field at the center point, which makes the reconstruction effect at the center point is the best, but the reconstruction effect at the non- central point is poor. In order to solve this problem, a non-central pint 3D sound field reconstruction method is presented. The proposed method finds the location of virtual loudspeakers by constructing a virtual sphere. The signals of virtual loudspeakers are solved by traditional method. By keeping particle velocity at the non-central point constant, the signal of real loudspeaker can be obtained from the signal of virtual loudspeaker.
