When bursty events occur, detecting the bursty events timely and proactively can improve resource scheduling efficiency, connection rate, and customer satisfaction. The existing bursty events detection methods are mainly dependent on human experience, which detect events untimely and incompletely. In this paper, an unsupervised approach of detecting bursty events based on speech-to-text data is proposed, which makes good use of multiple dimensional features of the field to detect and track bursty events. Using our method, we achieve performances of 90.46%, 86.22% and 86.15% w.r.t. the average precision, recall and F1 score respectively. The experimental results demonstrate that the proposed method is effective to detect bursty events among considerable speech-to-text data.","PeriodicalId":414908,"journal":{"name":"Proceedings of the 2021 5th International Conference on Computer Science and Artificial Intelligence","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122199998","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}

We believe that it is more important for anomaly detection to extract crucial representation from normal samples rather than more information, so we propose a semi-supervised method named LCR-GAN. We conducted extensive experiments on four image datasets and 15 tabular datasets to demonstrate the effectiveness of the proposed method.

In Enhanced-YOLOv3-tiny, we propose a new backbone named GhostDarkNet based on DarkNet53 and Ghost Module for decreasing the model parameters, which helps to get more representative features compared with YOLOv3-tiny. Furthermore, we put forward a new Multiscale Head, which adds three more heads and includes Ghost Module in each head to fuse multi-scale features.

A few researchers have proposed deep learning-based solutions such as ResidualNet, GrowNet and EnsembleNet. The latter two methods are both boost methods, which are more suitable for shallow network, and the model performance is basically determined by the first model, with limited effect of subsequent boosting steps. We propose a method based on self-distillation and bagging, which selects the well-performing base model and distills several student models by appropriate regression distillation algorithm. Finally, the output of these student models is averaged as the final result. This integration method can be applied to any form of network.

However, the biggest problem in online teaching is that it is difficult to predict students' academic performance. Therefore, it is necessary to design an effective method to predict students' academic performance more accurately. In this paper, a student academic level prediction method based on stacking model fusion is proposed. Logistic regression, random forest, XGBoost, and Naive Bayes are selected as base learners according to optimal fusion criteria and model properties. Furthermore, the structure and distribution of the features of the dataset are optimized by data preprocessing, feature coding, and feature selection, and the upper limit of the model expression is effectively raised. On this basis, according to the features of dataset and model performance, we select the appropriate model for model fusion, and further improve the prediction effect. Experiments are conducted on OULAD and xAPI datasets, and the results show that the prediction accuracy of the proposed method is better than that of traditional prediction methods. Finally, we analyze the factors that affect academic performance and give some specific suggestions.","PeriodicalId":414908,"journal":{"name":"Proceedings of the 2021 5th International Conference on Computer Science and Artificial Intelligence","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128727897","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}

However, the image data that can be used for computer vision training is very limited, so it is necessary to find an effective method to expand the datasets based on the existing image data. In this paper, we study methods to collect more training data from existing datasets and compare detectors’ performance trained with datasets generated by different methods. One method is to perform sampling-based on statistical properties of feature descriptors. For every feature, the underlying assumption is that a probability density function (PDF) exists, such PDF is approximated with existing training examples and new training examples are sampled from the approximated PDF. The other method is simply to expand the existing datasets by flipping each training example along its symmetric axis. Locally Adaptive Regression Kernel (LARK) feature is used in this paper because it is robust against illumination changes and noise. Our experimental results demonstrate that an expanded training dataset is not always preferable, even if the expanded dataset includes all original training data.","PeriodicalId":414908,"journal":{"name":"Proceedings of the 2021 5th International Conference on Computer Science and Artificial Intelligence","volume":"45 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126277872","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}

However, mining the potential explanatory factors or semantic associations behind data, rather than simply representing the superficial co-occurrence of words, remains a non-trivial challenge. To this end, we seek inspiration from the Quantum Entanglement (QE) which can effectively provide a complete description for the nature of realities and a globally-determined intrinsic correlation of considered objects, thus proposing a novel representation learning hypothesis called the Latent Semantic Correlation (LSC), namely the implicit internal coherence between the semantic space and its corresponding category space. To construct a multi-granularity representation from sememes to words, phrases, sentences, and higher-level LSC, we implement a QE-inspired Network (QEN) under the constraints of quantum formalism and propose the Local Semantic Measurement (LSM) and Extraction (LSE) for effectively capturing probability distribution information from the entangled state of a bipartite quantum system, which has a clear geometrical motivation but also supports a well-founded probabilistic interpretation. Experimental results conducted on several benchmarking classification tasks prove the validity of the LSC hypothesis and the superiority of QEN.","PeriodicalId":414908,"journal":{"name":"Proceedings of the 2021 5th International Conference on Computer Science and Artificial Intelligence","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127757912","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}
