An online learner can generate a multitude of learning analytics indicators that can be used to improve these learning systems using artificial intelligence algorithms. Nevertheless, the use of a large number of learning indicators causes overfitting that degrades the performance of machine learning algorithms. Therefore, in this paper, we will focus on the implementation of dynamic optimization of the number of learning indicators, based on the type of the considered task. This optimization will be done through two different machine learning algorithms: Naive Bayes Classifier for the classification tasks and Regression Decision Trees for the regression task. The adaptation of these two algorithms with various scenarios provides convincing results that demonstrate a significant improvement in the predictions made.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122084172","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}

Moreover, these ones can be used in any area such as service composition, business process construction, creating a complex service…Etc. In our work, we focused on the cloud services use for business process construction. But the problems that arise are firstly, the multitude of similar services for a business process construction and secondly, the divergence in the resource consumption of these services. In this paper we have chosen to use a formal model to describe, verify business process construction by using cloud services and to calculate for each business process activity the resource consumption of all similar services, in order to select the best services (which have a low resource consumption) for the business process construction. In such a way that selection of cloud services is done on the basis of a formal model to prove the correct execution and to achieve formal verification of the business process with a resources representation. In other words, it enables the selection of best similar cloud services based on re-source consumption and this is done through a transformation from a business process model to a formal model.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116754537","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}

The concept of goal is an important BDI agent’s component that plays a central role in this flexibility of behavior. Besides, as the concept of motive is another relevant one for the agent’s behavioral flexibility and as the BDI model originally does not include motives, some extensions of the BDI agent, with a new component for expressing the motive, have been proposed. In a recent work, it has been shown that the concept of motive can be specified via the goal concept, so it is not required to add a new component to express a motive. In this paper, we further explore this idea at the architectural level of a BDI agent. In particular, we look at how the added values of incorporating motives in BDI agents, can be obtained via the goal concept.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134519359","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}

In such a mission, it is essential to assign a unique identifier or label to each tracked object, regardless of the area, time of appearance, or detector camera, to distinguish it from other objects and to conserve as much information as possible about the tracked objects with the same label. This conservation is a significant issue, especially in largescale video surveillance systems, due to the linear complexity of the sequential search to find the labels of detected objects in data increasing with time, the number of tracked objects, and the number of active cameras in the network. To overcome this problem, we propose a new automatic multi-object labeling solution for efficient real-time tracking based on an indexing mechanism. This mechanism organizes the massive metadata of objects extracted during tracking into a tree-based indexing structure. The main advantage of this structure in a tracking system is its logarithmic search complexity, which implicitly reduces the search response time, and its quality of research results, which ensure coherent labeling of the tracked objects. This paper discusses the effectiveness of the label search algorithms and the tracking quality compared to other recent tracking systems on real-world datasets. Experimental results showed good performance in reducing search time and improving tracking quality.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131819130","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}

In this paper, we propose a novel model for NoSQL database access control that we aim that it will be dynamic. To be able to design such model, we have considered the Trust concept to compute the reputation degree for a given user that plays a given role.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115073962","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 introduce in this paper a collective technique for DDoS detection in wide network areas. Entropy of the distances traveled by the packets is calculated and exchanged between routers in order to locally decide if there is an ongoing DDoS or not. Contrary to most of the similar methods in the literature, that are based on the entropy of source addresses, we have opted for the entropy of the distances traveled by the packets in order to prevent IP spoofing techniques. Collective detection consists in combining decisions within local neighborhoods. Experiments using the platform OMNet++ show the potential of the new technique for efficient collective detection of DDoS attacks.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125490857","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, create and perform a single CL able to achieve multi-attributes self-adaptation is difficult. So, the system must include many CLs to ensure separation of concerns. The major challenge is that how multiple CL entities can interact with each other to coordinate the system management? On the other hand, how concerns can separate among different CLs? In this paper, we propose HCLs (Hierarchical Control Loops), a pattern for the manager sub-system, with benefits from the leveraging of the hierarchical and dynamic component model, Fractal. The proposed approach allows managing the complexity of self-adaptation by separating concerns using Fractal component model in the form of an hierarchy of MAPE loops. Furthermore, we distinguish three types of adaptations as following: Local Adaptation, Regional Adaptation, and Superior Adaptation in order to achieve multi-level adapting.","PeriodicalId":284572,"journal":{"name":"2021 International Conference on Theoretical and Applicative Aspects of Computer Science (ICTAACS)","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124589176","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}
