Moreover, due to the subjective influence of people and the unstable return of traditional investment, more and more institutions gradually start to use the quantitative stock selection model in order to get higher return in pursuit of lower risk. As the most classic algorithm in quantitative stock selection, multi factor model is favored by many institutional investors. However, due to the difference of financial system between China and western countries, the existing quantitative model in western countries is not fully applicable in China. At the same time, the previous multi factor stock selection models have more subjective factors and less consideration of time series, so the earning rate is usually not so good. In order to pursue a higher earning rate, in this paper, by taking the impact of time series into consideration, a multi factor quantitative stock and transaction timing selection model has been proposed based on information coefficient (IC) mean value scoring. And by choosing constituent stocks in Shanghai and Shenzhen 300 (HS300) Stock Index have been chosen as the target, the effectiveness of proposed model has been analyzed and verified.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125844109","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}

Therefore, this paper conclusion MIMO-ISAR high-resolution imaging from three aspects, first summarizes the sub-band synthesis technology to achieve one-dimensional distance image high-resolution. Second, systematically expounds the basic method of Doppler blurring of MIMO-ISAR echo data.

However, the size of the pin itself is small, the characteristics of different angles vary greatly, and the surrounding environment may be complicated. The traditional manual inspection method is no longer suitable for the increasingly large transmission network. In response to the above problems, this paper proposes a detection method for bolt bolts of transmission towers based on the attention mechanism. First, preprocess the input pin image, and then scan the image with a perturbation neural network that includes an attention mechanism to get the most likely area, and cut and save the area for further processing. This can reduce The useless information on the image increases the proportion of the pins on the image. After multiple rounds of focusing, a pin image with obvious characteristics can be obtained. Secondly, the deconvolutional perturbation neural network is used to establish the feature mapping relationship from the whole to the partial pin image. Thirdly, according to the closed-loop control principle, the distinguishability evaluation index is used to obtain the difference of the extracted features in the feature space. According to the evaluation results, the feature space is layered, the images with large feature deviations are separated and recombined into a new data set, which is then used as the training set of the next level model to retrain the new model, and then based on the evaluation The result of the decision determines whether to continue to layer the training set, realize the multi-level feature space separation and self-optimization adjustment mechanism of the recognition structure, and establish a multi-level model recognition system with stronger generalization ability.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132599700","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}
