In order to ensure the normal and stable delivery of artistic lighting systems to the actual high-altitude icy/snowy areas, methods such as theoretical research, experimental analysis, modeling, algorithm improvement, and case study are adopted to study the delivery of artistic lighting systems in high-altitude cold conditions. Based on the actual demand for the delivery of artistic lighting systems to high-altitude icy/snowy areas, the Fuzzy Time-Windows constraint is formulated; the objective functions for maximizing customer satisfaction with artistic light shows and minimizing the total cost of the delivery of lighting systems are designed; customer satisfaction with light shows is converted into a constraint and thus a single objective function is established. Based on the single objective function, a static initial model with time window constraints is constructed. The Shennongjia International Ski Resort in Hubei Province is selected for empirical analysis. Based on the static initial model and dynamic model constructed by using the genetic algorithms for nonlinear programming, three analyses are completed. According to the analyses, the cost of a single light show using the artistic lighting systems is relatively low, and as the places in need of lighting systems increase, the cost of artistic lighting systems will be increasingly lower than that of fixed light sources.","PeriodicalId":222463,"journal":{"name":"2021 International Conference on Culture-oriented Science & Technology (ICCST)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116351470","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}

Using the existing algorithm and the LPSV in this paper, the speaker power in the cultural complex is calculated respectively, and the total power of the loudspeaker required in the hall can be directly obtained by using the LPSV through the volume of the hall. The 3D model of the hall is established by EASE, which is used to calculate and simulate the sound reinforcement technical parameters such as analogical pressure level, articulation loss, and rapid speech transmission index. In the aspects of maximum sound pressure level, sound field nonuniformity, and transmission frequency characteristics, according to the above analysis of the data, it meets the “Design specification of hall sound amplification system” (GB50371-2006).

Even in many practical application scenarios of the recommendation system, there is only implicit feedback without explicit feedback Based on implicit feedback to recommend there has been a problem, that is usually implicit feedback provides only reflect the noise signal of user preferences, because although the observed interactions at least reflect the user’s interest in the item, but not observed the interaction may be missing data, and is not necessarily negative samples, so it’s natural lack of negative feedback In this work, this paper improves the neural colla-borative filtering algorithm (NCF) by extracting the popularity characteristics as the basis for extracting negative samples from implicit feedback data. To a certain extent, it solves the problem that negative sampling introduces a lot of noise in previous work. At the same time, we found that the gradient vanishing in the training process when using the traditional loss function Binary Cross Entropy (BCE). In order to solve this problem, a new loss function, BCE-Max, was proposed in this paper. Based on the above improvements, we proposed a neural collaborative filtering recommendation algorithm (PNCF) based on popularity characteristics. By comparing the performance of PNCF, NCF, traditional collaborative filtering and some matrix factorization recommendation algorithms in the evaluation indexes such as HR@10, NDCG@10 and avg_popularity@10, we find that PNCF has certain advantages over these recommendation algorithms. Meanwhile, We found that compared with NCF, the experimental results of PNCF improved by about 1.2% and 2% onHR@10 and NDCG@10 respectively, and even improved by about 2% on HR@1 and NDCG@I.","PeriodicalId":222463,"journal":{"name":"2021 International Conference on Culture-oriented Science & Technology (ICCST)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124259166","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}
