Secondly, using the average pooling and max pooling characteristics in the feature map channel and space, we proposed the parameter-free attention module. Finally, the recognition rate was compared to the common attention module and the deeper residual network. The experimental results show that the recognition rate of Resnet18 network with the PFAM is superior to attention modules SE and CBAM and deeper residual networks, and the recognition rate on self-built infant facial expression dataset exceeds that of the ResNetl01, and the recognition rate on public facial expression dataset RAF-DB exceeds that of the ResNetl52.","PeriodicalId":231070,"journal":{"name":"2022 International Conference on Artificial Intelligence and Computer Information Technology (AICIT)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117150043","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}

With the expansion of food demand due to rapid population growth in recent years, many crops have been damaged by pests due to frequent natural disasters, which have caused serious damage to farmers’ economic development. As an important biological disaster in agricultural production in China and the world, crop pests and diseases are the biggest cause of sustainable and stable development of agricultural production, with a wide range of species, high impact and high potential for outbreaks becoming its label. Accurate detection of pests is therefore an urgent necessity for the excellent development of the crop industry. In this paper, the binary cross-entropy loss in YOLOX is changed to Focal loss, an attention mechanism is added to its backbone feature extraction network Backbone to make the model more edge-oriented, and a depth-separable convolution is introduced to reduce the number of parameters. The improved pest detection model obtained a recall of 93% and an average accuracy of 87.6%, which can be effectively applied in real life.","PeriodicalId":231070,"journal":{"name":"2022 International Conference on Artificial Intelligence and Computer Information Technology (AICIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127497155","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}

Aiming at the problem of excessive computational overhead of the Dynamic Time Warping algorithm(DTW), the algorithm divides the original sequence into several sequence segments, and defines the distance of the sequence segments according to their geometric characteristics. In the dynamic matching stage, sequence segments are used as the basic matching unit to solve the problem that the computation overhead caused by traditional point-by-point matching strategy is too high.

Although coping with huge scale differences and high inter-class similarity was made possible by multi-scale information fusion, the multiscale weight fusion technique neglected the impact of cross-scale on picture semantic feature extraction, leading to subpar detection performance. The performance of the delayed inference was caused by the rotating region proposal network, which produced high-quality ideas while expanding the network’s capacity. In this study, a cross-scale shift oriented object detection method was suggested. First, by creating a feature pyramid network, the multi-layer feature maps were successfully fused.

A cross-scale shift module was simultaneously introduced to FPN to enhance the correlation between multi-scale properties.
