To reduce the execution delay, computation-intensive multimedia tasks can be offloaded from user equipments (UEs) to the MEC server. How to allocate the computational and wireless resources is one of the key issues to guarantee the quality of services, and is very challenging when tasks are generated dynamically. In this paper, we address the above problem. To minimize the sum execution delay of multiple users, we jointly optimize the offloading decision and the allocation of both computational and wireless resources. We propose a deep policy gradient (DPG) algorithm based on the deep reinforcement learning. Simulation results show that our proposed DPG method can achieve lower latency than the baselines under different numbers of users, computation capacities and wireless bandwidths.","PeriodicalId":150308,"journal":{"name":"Proceedings of the 12th EAI International Conference on Mobile Multimedia Communications, Mobimedia 2019, 29th - 30th Jun 2019, Weihai, China","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129968621","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, data stored on the cloud is vulnerable to unauthorized access during the sharing process. The traditional conditional proxy broadcast re-encryption solution is suitable for the above application scenarios but does not support flexible control of conditions. This article describes the concept of finegrained conditional proxy broadcast re-encryption (FGC-BPRE). The scheme utilizes an access tree to generate a re-encryption key. If the ciphertext keyword satisfies the conditions in the access tree, the proxy can convert the user's ciphertext into a new ciphertext for a group of users. In addition, this paper also constructs a fine-grained conditional proxy broadcast re-encryption scheme and verifies the security of selective ciphertext attacks without oracles.","PeriodicalId":150308,"journal":{"name":"Proceedings of the 12th EAI International Conference on Mobile Multimedia Communications, Mobimedia 2019, 29th - 30th Jun 2019, Weihai, China","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125682984","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, due to economic or fame reasons, dishonest people are employed to write fake reviews which is also called “opinion spamming” to promote or demote target products and services. Previous research has used text similarity, linguistics, rating patterns, graph relation and other behavior for spammer detection. It is difficult to find fake reviews by a glance of product reviews in time-descending order while It’s more easy to identify fraudulent reviews by checking the list of reviews of reviewers. We propose sieries of novel review grouping models to identify both positive and negative deceptive reviews. The review grouping algorithm can effectively split reviews of reviewer into groups which participate in building new model of review spamming detection. Several new features which are language independent based on group model are constructed. Additionally, we explore the collusion behavior between reviewers to build group collusion model. Experiments and evaluations show that the review group method and relevant models can effectivly improve the precision of 4%-7% in deceptive reviews detection task especially those posted by professional review spammers.","PeriodicalId":150308,"journal":{"name":"Proceedings of the 12th EAI International Conference on Mobile Multimedia Communications, Mobimedia 2019, 29th - 30th Jun 2019, Weihai, China","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124597049","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}

Signal is obtained by color channels separation of ROI and independent component analysis. Next we filter signal with bandpass filter and extract heart rate from the blood volume pulse via Fourier transform. Meanwhile, the trajectory is decomposed into a set of component motions by calculating the feature points at the chest and performing principal component analysis. The composition of the respiration that is most suitable for the calculation is then selected based on its time spectrum. Finally, the peak of the trajectory corresponding to the respiration is determined.

This paper proposes an adaptive filter fusion localization mechanism with LSTM network correction. Firstly, a data preprocessing method is designed to convert IMU data from the carrier coordinate system to the geographical coordinate system. Then, based on kinematics theory, the state equation and measurement equation of Adaptive Kalman Filter are established and the system state noise is obtained. Furthermore, the model adaptively to update the carrier coordinate, system state noise and measurement noise. Finally, the carrier trajectory coordinates predicted by the coupled LSTM model are used to obtain the final positioning results and complete the carrier trajectory filtering.
