Sometimes the same covariance is shared for all the clusters. This assumption is very restricted and it might be more meaningful that each cluster will be defined not only by its centroid but also with the covariance matrix. However, its use for k-means algorithm is not appropriate for optimization. It might lead to a good and meaningful clustering, but this is a fact of empirical observation and is not due to the algorithm’s convergence. In this study we will show that the overall distance may not decrease from one iteration to another, and that, to ensure convergence, some constraints must be added. Moreover, we will show that in an unconstrained clustering, the cluster covariance matrix is not a solution of the optimization process, but a constraint.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121474556","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}

This is due to the finite speed of signal propagation which cannot exceed the speed of light at vacuum, which in turn means that when summing the total force in the system the force does not add up to zero. This was demonstrated in a specific example of two current loops with time dependent currents, the above analysis led to suggestion of a relativistic engine [2], [3]. Since the system is effected by a total force for a finite period of time this means that the system acquires mechanical momentum and energy, the question then arises if we need to abandon the law of momentum and energy conservation. The subject of momentum conversation was discussed in [4], while the subject of electric energy conservation was discussed in [5]. Here some preliminary aspects of the exchange of energy between the mechanical part of the relativistic engine and the magnetic field are discussed and the methods to distinguish between mutual inductance energy terms which are unrelated to the motion of the engine and magnetic terms which are the result of the motion.

Unlike fractional Brownian motion (fBm) governed by a unique parameter (Hurst exponent), p-fBm is defined by three parameters: the Hurst exponent in low frequencies, the Hurst exponent in high frequencies and the threshold frequency, which separates the two regimes. In this paper, we present a synthesis method that generates a finite approximation of p-fBm series. Moreover, we analyze the synthesized p-fBm series and test the Gaussianity of both p-fBm and p-fGn. We test the stationarity of the first order increments (p-fGn) and explore an approach to estimation of the process Hurst parameters. Our contribution is relevant to modeling and analysis of certain textures that are characteristic of certain medical and other natural images.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134268644","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}

A combination of beam forming and scheduling can thus improve the performance of multi-user MIMO systems. Furthermore, in realistic conditions, data packets have both priority and deadlines beyond which they become obsolete. In this paper we propose a simple scheduling algorithm which takes priorities and deadlines into account and allocates users to resource blocks and spatial beams. We demonstrate the merits of the proposed technique compared to other state-of-the-art scheduling methods through simulations.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133126969","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 employ machine learning classification algorithms to recognize the smartphone modes (e.g. pocket or swing) and thereby enabling the choice of a proper gain value to improve PDR positioning accuracy. In particular, we focus on two classification approaches: 1) tree based approaches: random forest, gradient boosting and CatBoost 2) neural network approaches: convolutional neural network, recurrent neural networks with long short-term memory units, gated recurrent unit and residual recurrent neural networks. Experimental results obtained using thirteen participates walking in an inhomogeneous environments and smartphone modes show successes of more than 97% in classifying the smartphone modes using neural network approaches.","PeriodicalId":254455,"journal":{"name":"2018 IEEE International Conference on the Science of Electrical Engineering in Israel (ICSEE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122340232","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}
