Both the government and consumers are paying more and more attention to the inspection of the hygienic quality and safety of seafood. Freshness is an important indicator of the quality of seafood products, and it is very important to the final quality of the products.

At present, there are still two important problems to be solved. One is that the chaos degree of chaotic sequence is not enough due to improper selection of initial parameters and the other is easy to solve by using chaotic encryption and decryption alone. In this paper, a digital image encryption and decryption algorithm based on optimization and fusion strategy is proposed. Firstly, the parameters of chaos parameters are optimized by genetic algorithm to obtain a better chaotic Logistic mapping encryption relationship. Then, the fusion encryption is carried out by two-level permutation and one-level diffusion technology. Finally, the corresponding decryption algorithm is given in this paper.

It has powerful feature extraction and learning capabilities. Because of its various advantages, it has been applied in many fields. Object detection is an important technology in deep learning, and object detection based on deep learning has also been studied by many people. With the gradual improvement of people's living standards, pets have gradually received people's love, among which pet dogs occupy the majority. Different types of pet dogs will bring different problems. For example, large pets may be more aggressive and cause problems for city management. If dangerous pets can be distinguished in time, it can bring more security to people and avoid some people being bitten by pet dogs. In the deep learning algorithm, YOLOv3 has better object detection performance, but it only targets different species and objects, and the classification of different categories of specific species is not good enough. In daily life, the body of the pet dog is sometimes hidden by the complicated background, which makes it difficult to extract the overall characteristics of the pet dog. At this time, the facial features of the pet dog can be fully utilized to distinguish the pet dog. In order to solve this problem, this paper proposes an improved yolov3 model for face detection and categorization of pet dogs. This paper establishes a data set of 8 different kinds of pet dogs. The data set is divided into training set and a test set, and the training set is sent to the established model for training. Finally, we use the test set to verify the effect of the model. This paper establishes a data set of 8 different kinds of pet dogs. Pet dog types include Akita, Golden Retriever, Poodle, Pomeranian, Samoyed, Corg, Pug, and Husky. Experiments show that this paper can realize the detection and classification of pet dogs with high detection speed and accuracy, and mAP(mean Average Precision) can reach 94.91%.","PeriodicalId":236797,"journal":{"name":"2020 13th International Symposium on Computational Intelligence and Design (ISCID)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452125","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}

It is a crucial step in information extraction from unstructured data and building a Knowledge Graph (KG). The performance of deep learning methods for RE, like Recurrent Neural Network (RNN) and Convolutional Neural Network (CNN), heavily depends on the quality and scale of the training set. Recently, pre-training models like BERT and ERNIE, have achieved State-Of-The-Art (SOTA) results in many NLP tasks, because they can obtain the prior semantic knowledge during the procedure of pre-training. Therefore, it is interesting to know whether the performance of RE can be improved utilizing the pre-training models. In this paper, we propose a method of RE using two kinds of pre-training models: BERT and ERNIE. First, in the input sequence, unique symbols are appended around the entities. RE is then regarded as a text classification task, and the prior semantic knowledge obtained by pre-training models is used to improve the performance. Experiments are carried on the SemEval 2010 Task 8 dataset. Results demonstrate that the method we proposed improves the performance of RE compared with previous approaches.","PeriodicalId":236797,"journal":{"name":"2020 13th International Symposium on Computational Intelligence and Design (ISCID)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125993551","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}
