The contradiction between group benefit and individual benefit hinders group cooperation and further is detrimental to group performance. Thus, when measuring or promoting group performance, how to predict and avoid hitchhiking has become a key issue. Classical game models are widely used as specific backgrounds to explore cooperation, which are relatively easy to explain but hard to apply. To find the commonly used methods to promote group performance, this paper abstracts the basic characteristics of group events, and then influence the strategic choices of the group members by adjusting event characteristics. So we can get the means to enhance cooperation and avoid the hitchhiking phenomenon. The results of this study are relatively universally applicable and are conducive to boost the performance of various group events.","PeriodicalId":357409,"journal":{"name":"Proceedings of the 2019 2nd International Conference on Algorithms, Computing and Artificial Intelligence","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125369604","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, there are still some practical problems affecting the robustness and accuracy of SLAM, including the impact of highly dynamic environments. In this paper, we propose a real-time SLAM system, named DOS-SLAM, which is specifically designed for dynamic environments. The system, based on ORB-SLAM2, adds two modules to achieve accurate in highly dynamic environments, dynamic object segmentation with instance segmentation and geometric constraint and static semantic octo-tree map to realize a static map without moving objects. TUM RGB-D Dataset is used to present the performance of DOS-SLAM, and it has been proved that DOS-SLAM has outstanding and superior performance in dynamic environment. Meanwhile, it can realize real-time computing. In addition, static semantics octo-tree map built by DOS-SLAM system occupies less memory and only contains static objects, which is more conducive to robot navigation and large-scale scene map generation.","PeriodicalId":357409,"journal":{"name":"Proceedings of the 2019 2nd International Conference on Algorithms, Computing and Artificial Intelligence","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114905972","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}

During the error back propagation, our model focus on the salient statistical structure by allowing a sub-network to approximate the nonzero sub-matrix. Finally, we trained our model on a public Wikipedia corpus and evaluated on word analogy, word similarity tasks and documents clustering and classification. The results show that our method yields almost 4% improvement on word analogy and nearly 3% improvement on word similarity tasks compared to state-of-the-art methods. The evidences demonstrate that SPC outperform baseline and the state-of-the-art methods on all tasks.","PeriodicalId":357409,"journal":{"name":"Proceedings of the 2019 2nd International Conference on Algorithms, Computing and Artificial Intelligence","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115330825","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, there is only little research in developing chatbot-hotel in Indonesia. Chatbot has many advantages for both hotel and mobile users to improve convenience, reduce service, sales and support costs, one-to-one marketing and new data collections. Using chatbot, customers using smartphone can reach a hotel anytime and anywhere with personalized services related to their needs. The customers can find out availability of rooms, price, booking and have a personal front office that provide the real-time and context-relevant information about hotel services. Therefore, we develop an interactive intelligent personalized chatbot-hotel by using AIML and Google Flutter. Flutter is used as it is easy to develop the chatbot-hotel in the cross-platform mobile application. The outcome of this work is a prototype chatbot-hotel on mobile platform especially for Indonesian users. This chatbot includes all services in the hotels and able to give the personalized services to the customers before arrive in the hotel.

It is a com- binatorial optimization problem, and this combinatorial optimiza- tion problem is NP-hard. Most existing pruning methods prune channels/neurons based on the assumption that they are indepen- dent in network. However, there exists dependency among chan- nels/neurons. We try to solve the combinatorial optimization problem by evolutionary algorithm (EA). However, the traditional EA can't be used directly into deep neural networks (DNNs) because the problem dimension is too high. Attention mechanism (AM) can help us get parameter important score to reduce prob- lem difficulty, making the architecture search process more effective. Therefore, combining EA and AM, we propose an Evolutionary NetArchitecture Search (EvoNAS) method to solve network pruning problem. We demonstrate the effectiveness of our method on common datasets with ResNet, ResNeXt, and VGG. For example, for ResNet on CIFAR-10, EvoNAS reduces 73.40% computing operations and 73.95% parameters with 0.13% test accuracy increasement. Compared with the state-of-the-art methods, EvoNAS increases 30% reduction ratio at least.","PeriodicalId":357409,"journal":{"name":"Proceedings of the 2019 2nd International Conference on Algorithms, Computing and Artificial Intelligence","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124015052","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}

Humanity crisis in countries such as Yemen and Syria led people to utilize Twitter as a crisis communication tool to overcome uncertainty. A variety of crisis-related messages is sent to enquire about different issues. The content of these messages is used by humanitarian organizations to form the response plan. However, most of these messages are in the Arabic language that covers information about the humanitarian crisis. Classifying their content relay on annotated corpus. Though, most of the crisis corpora available are in the English language and focusing on natural hazards. In this paper, we present the first humanity crisis corpus in the Arabic language using Twitter data which annotated data into five-crisis categories. Then, classification was performed through three different experiments using TFIDF, lexical, morphology and word embedding features. After that supervised learning algorithms were trained with and without word2vec models. Results indicate that classifiers are detecting more Arabic crisis-message classes when they are trained with skip-gram with TFIDF, lexical and morphology extracted features. Moreover, we generated Arabic crisis word embedding with similarity weighting trained by word2vec techniques in each crisis category. This paper is a baseline for Arabic crisis-message classification in social media and opens up prospects for future inspiring ideas in this field.","PeriodicalId":357409,"journal":{"name":"Proceedings of the 2019 2nd International Conference on Algorithms, Computing and Artificial Intelligence","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129723950","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}
