In view of the existing problems in scalability, usability and other aspects of the solution in current researches, we propose the distributed dynamic cuckoo filter system based on Redis cluster. On one hand, we introduce an efficient hash indexing structure–dynamic cuckoo filter (DCF), which only stores the fingerprint information of data, and has the automatically scalable capacity to meet the demand of data storage on a dynamic scale. On the other hand, we use an improved consistent hashing algorithm to construct Redis cluster and use the thorough communication mechanism of Redis cluster to achieve the data sharing and efficient utilisation of multi-machine filters. The scheme proposed in this paper can take the time and space efficiency into account, greatly promote the retrieval performance of massive data, and improve the reliability and availability of Redis cluster.","PeriodicalId":45411,"journal":{"name":"International Journal of Parallel Emergent and Distributed Systems","volume":"35 1","pages":"340 - 353"},"PeriodicalIF":1.1,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17445760.2019.1599889","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46109067","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 algorithm simplifies particle updating formula, and uses logistic chaotic sequence to initialise the particle position, which can improve the global search ability of population; nonlinear decrease extreme disturbance strategy enhanced the diversity of the population and avoid the particles trapping in local optimum; a novel Cauchy mutation is used for the optimal particle variation to generate more optimal guiding particle movement. The experimental simulation on seven typical test functions shows that the proposed algorithm can effectively avoid falling into local optimal solution, the search speed and optimisation accuracy have improved significantly. The algorithm is suitable to solve the function optimisation problem.","PeriodicalId":45411,"journal":{"name":"International Journal of Parallel Emergent and Distributed Systems","volume":"35 1","pages":"236 - 245"},"PeriodicalIF":1.1,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17445760.2018.1455834","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49110346","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}

Traditional methods are based on the pipeline of pre-processing, feature extraction, dimensionality reduction and emotion classification. Previous studies have focussed on emotion recognition based on two different models: discrete model and continuous model. Both the speaker's age and gender affect the speech emotion recognition in the two models. Moreover, investigation results shown that the dimensional attributes of emotion such as arousal, valence and dominance are related to each other. Based on these observations, we propose a new attributes recognition model using Feature Nets, aims to improve the emotion recognition performance and generalisation capabilities. The method utilises the corpus to train the age and gender classification model, which will be transferred to the main model: a hierarchical deep learning model, using age and gender as the high level attributes of the emotion. The public databases EMO-DB and IEMOCAP have been conducted to evaluate the performance both in the classification task and regression task. Experiment results show that the proposed approach based on attributes transferring can improve the recognition accuracy, no matter transferring age or gender.","PeriodicalId":45411,"journal":{"name":"International Journal of Parallel Emergent and Distributed Systems","volume":"35 1","pages":"354 - 364"},"PeriodicalIF":1.1,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17445760.2019.1626854","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46819276","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 large-scale spatial interpolations, it is always needed to find a local set of data points for each interpolated point using the k Nearest Neighbor (kNN) search. To improve the efficiency of kNN, the uniform grid is commonly employed to fastly locate neighbours, and the size of grid cell could strongly affect the efficiency of kNN search. In this paper, we evaluate effects of the size of uniform grid cell on the efficiency of kNN search which is implemented on the CPU and GPU. We employ the Standard Deviation of points’ coordinates to measure the spatial distribution of scattered points. For irregularly distributed scattered points, we perform several series of kNN search in two- and three-dimensions. Benchmark results indicate that: for both the sequential version implemented on the CPU and the parallel version implemented on the GPU, with the increase of the Standard Deviation of points’ coordinates, the relatively optimal size of the grid cell decreases and eventually converges. Moreover, relationships between the Standard Deviation of scattered points’ coordinates and the relatively optimal size of grid cell are fitted.

In 2017, Zhang et al. proposed a new measure for the fault diagnosis of systems, namely, g-extra conditional diagnosability, which requires that every component of G−F has more than g vertices in the system.

In this work, we study architectural-level contributions to energy dissipation in an Artificial Neural Network (ANN)-based processor that is trained to perform edge-detection task. We compare the training and information processing cost of ANN to that of conventional architectures and algorithms using 64-pixel binary image. Our results reveal the inherent efficiency advantages of an ANN network trained for specific tasks over general-purpose processors based on von Neumann architecture. We also compare the proposed performance improvements to that of Cellular Array Processors (CAPs) and illustrate the reduction in dissipation for special purpose processors. Lastly, we calculate the change in dissipation as a result of input data structure and show the effect of randomness on energetic cost of information processing. The results we obtained provide a basis for comparison for task-based fundamental energy efficiency analyses for a range of processors and therefore contribute to the study of architecture-level descriptions of processors and thermodynamic cost calculations based on physics of computation.

Here, we focus on the topics of personal computers (PCs). We can see PCs produced in Japan have very unique features. They coevolved with some other related machines, e.g. word processing machines, game machines, etc. They also had several localised features such as capability of dealing with Japanese language. At the same time, developers of PCs struggled to find a good solution between localisation and globalisation. In the early stage of the history of PCs, their architectures were all different, and software had to be developed and tuned for each of them. Thus providing a common platform to all PCs on which every software can run was indispensable for globalisation. In this paper, how PCs in Japan have been evolved and how such problems were attacked are discussed based on the author's experiences of developing early PCs.
