We propose a new method, called DP-Thresholding, to achieve a non-trivial $l_{2}$-norm based error bound, which is significantly better than the existing ones from adding noise directly to the empirical covariance matrix. Experiments on the synthetic datasets show consistent results with our theoretical claims.","PeriodicalId":123696,"journal":{"name":"2019 53rd Annual Conference on Information Sciences and Systems (CISS)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122759129","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}

Closed form expressions for eigenvalues and eigenvectors of such Toeplitz matrix are available. Those eigenvectors are used to design the eigenportfolios of the model. The Sharpe ratios and PNL curves of eigenportfolios for stocks in Dow Jones Industrial Average (DJIA) index for the period from July 1999 to Nov. 2018 are calculated to validate the model. The proposed method provides eigenportfolios that closely mimic the eigenportfolios designed based on empirical correlation matrix generated from market data.

This paper develops a queuing model of such carsharing platforms where cars may be deployed for transportation services at a given price, but also for grid services during transportation-idle periods through energy price arbitrage. The model provides a characterization of revenue from each of these two streams. The paper further finds optimal pricing and battery splitting to maximize revenue for the carsharing platform, via an analysis of the reward structure and an optimization algorithm. Platform revenue is assessed for various system parameters under optimal operation.","PeriodicalId":123696,"journal":{"name":"2019 53rd Annual Conference on Information Sciences and Systems (CISS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122612013","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}

On the other hand, with stringent delay-bounded and error-rate-bounded QoS requirements for 5G applications, the traditional Shannon capacity is no longer appropriate to characterize the maximum achievable data transmission rate given the block error probability. Towards this end, the finite blocklength coding (FBC) technique has been developed to support the new type of Ultra-Reliable and Low Latency Communications (URLLC). However, since the existing approximations of the transmission rate are neither convex nor concave in terms of the transmit power in the finite blocklength regime, it is challenging to formulate and solve the resource allocation optimization problems for URLLC over various different wireless fading channels while guaranteeing the statistical delay-bounded QoS requirements. To overcome the aforementioned problems, we propose the energy efficient FBC based cross-layer design while guaranteeing the statistical delay-bounded QoS requirements for URLLC. In particular, we establish and analyze FBC based wireless network models. By taking into account the statistical delay-bounded QoS constraints, we formulate and solve the ε-effective energy efficiency optimization problem using FBC. Also conducted is a set of simulations which validate and evaluate our proposed FBC scheme under the statistical delay-bounded QoS constraints for URLLC.","PeriodicalId":123696,"journal":{"name":"2019 53rd Annual Conference on Information Sciences and Systems (CISS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127032814","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}

To this end, numerous online algorithms such as Receding Horizon Control and Online Balanced Descent have been designed. However it is difficult for cloud service providers to select the best control algorithm dynamically for resource provisioning when confronted with consumer resource demands that are notoriously unpredictable and volatile. Furthermore, it highly possible that it might not be the case for any one algorithm to consistently perform well over the months-long contract period. In this paper, we first exemplify the need to address non-stationarity in cloud computing by showcasing traces from MS Azure. We then develop a novel meta-algorithm that combines change point detection and online optimization. The new algorithm is shown to outperform existing solutions in real-world trace-driven simulations.","PeriodicalId":123696,"journal":{"name":"2019 53rd Annual Conference on Information Sciences and Systems (CISS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130739960","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}

After establishing that these hypotheses satisfy several properties, we employ results from general min-imax lower bound theory to obtain the desired k-monotone regression minimax lower bound.

The ability to store multiple bits of data in each floating-gate device for a long amount of time allows for ideal use as hardware accelerators for neural networks. However, current implementations of the technology are impeded by large peripheral circuit overhead. In this work, steps towards a fully-realized NVM-based VMM ASIC are taken. In the 55-nm process, a test array of embedded NOR-flash memory (ESF3) from SST was implemented and fabricated. Multi-bit storage has been demonstrated within the 2x2 array via voltage-mode programming. Secondly, behavioral emulation of the VMM is implemented on a Kintex-7 FPGA to prototype the digital periphery, algorithms, and configurations necessary to embed the NVM-based VMM in a system on chip (SoC).

This paper aims to study two principal gain mechanisms introduced in NR (compared to LTE) targeting spectral efficiency improvements -(i) high order MU-MIMO with up to 12 layer spatially multiplexed transmission and (ii) higher resolution of CSI feedback with Type II feedback mechanism. In order to perform a fair comparison between LTE and NR, we maintain the same overhead, sub-carrier spacing and antenna configurations among other parameters. Although it is known that NR can provide benefits over LTE in terms of deployment flexibility, spectral efficiency and latency using mechanisms like multiple numerology support, lower control channel and reference signal overhead or lower guard bands we believe that the gain mechanisms (i) and (ii) are fundamental and a quantification of this aspect is attractive to operators and vendors who may consider NR or LTE deployments in sub-6 GHz bands.","PeriodicalId":123696,"journal":{"name":"2019 53rd Annual Conference on Information Sciences and Systems (CISS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121851507","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}
