A sensor orchestration is required to adapt to non-stationary environments, even if it is applied in streaming data scenarios where labelled data are scarce or not available. Without labels in dynamic environments, it is challenging to determine not only the accuracy of a classifier but also its reliability. This contribution proposes monitoring algorithms intended to support sensor orchestration in classification tasks in non-stationary environments. Proposed measures regard the relevance of features, the separability of classes, and the classifier's reliability. The proposed monitoring algorithms are evaluated regarding their applicability in the scope of a publicly available and synthetically created collection of datasets. It is shown that the approach (i) is able to distinguish relevant from irrelevant features, (ii) measures class separability as class representations drift through feature space, and (iii) marks a classifier as unreliable if errors in the drift-adaptation occur.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114175483","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 context, we propose a new dynamically adaptive processor design that is capable of delivering the best trade-off among these three axes according to the application at hand, or be tuned to optimize a specific metric. This is achieved by extending a polymorphic processor that can change its issue-width during runtime with specific mechanisms for fault tolerance, energy optimization, and performance enhancement. They are controlled by an optimization algorithm that evaluates and chooses which is the best configuration according to given requirements. Considering a metric that weighs all three axes, the proposed adaptive processor delivers a result that is 94.88% of the oracle processor on average, while a static configuration (defined at design time without runtime adaptation) only achieves 28.24% at most, which means that dynamic adaptation is required to cope with different application behaviors as there is not one specific configuration that fits all applications.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115298509","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}

Addressing the problem that harvested energy is unstable, nonvolatile processors (NVPs) have been proposed to hold intermediate data and avoid frequent program restarting from the beginning. However, NVPs often suffer a lot of waste on energy and system sources that can not be used for program execution owing to the frequent backup and recovery operations. To further improve the performance of NVPs, the paper proposes a dual-threshold method to maximize execution progress by enabling a system to hibernate to wait for power resumption instead of backing up data directly upon power interruptions. In particular, the optimal high and low thresholds, and the switches of system hibernation and backup, are discussed in details in order to achieve the goal of maximizing computation progress. The evaluation results show an average of up to 82.3% reduction on power failures and 1.5x speedup for forwarding progress by the proposed dual-threshold method compared to the conventional single threshold scheme.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126547097","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}

Three dimensional (3D) design, carbon nanotube materials, memristor based neuromorphic computing, and optical, RF and magneto-inductive (MI) wireless communication solutions are recently proposed. MI channels are non-radiative and non-interfering by forming coupled networks. They are future promising with capabilities of THz frequency, Tbit/s data rate, hundreds of zJ/bit and 109 W/mm2 communication and power transfer (PT) efficiencies, respectively. In addition, recently introduced network topology modulation (NTM) for MI channels provides network communication with low complexity, low latency and simultaneous wireless information and power transfer (SWIPT). In this article, unique advantages of THz MI channels, NTM design, nanoscale materials including graphene and single molecular magnets (SMMs), and 3D design are combined in a novel on-chip computing architecture denoted by MIComp by introducing fully efficient SWIPT for computing purposes. The system is theoretically modeled while the state space of the system obtained with nanoscale size coils and SMMs achieves 1010 to 1016 bits in each cycle and per mm3 volume of chip compared with the current transistor counts of on the orders of 109 per mm2. Furthermore, each MIComp cycle has ability to perform for multiple purposes consisting of computing operations, memory state implementations and on-chip communications. It promises a novel solution for communication, energy and space bottlenecks for on-chip computing design.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124853846","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}

We verify the MixColumn/MixNibble transformation using MDS matrices and propose reliability approaches for thwarting natural and malicious faults. We note that one other contribution of this work is to consider not only linear error detecting codes but also recomputation mechanisms as well as fault space transformation (FST) adoption for lightweight cryptographic algorithms. Our intention in this paper is to propose reliability and error detection mechanisms (through linear codes, recomputations, and FST adopted for lightweight cryptography) to consider the error detection schemes in designing beforehand taking into account such algorithmic security. We also posit that the MDS matrices applied in the MixColumn (or MixNibble) transformation of ciphers to protect ciphers against linear and differential attacks should be incorporated in the cipher design in order to reduce the overhead of the applied error detection schemes. Finally, we present a comparative implementation framework on ASIC to benchmark the VLSI hardware implementation presented in this paper.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115536515","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 present opportunistic named functions, a novel approach to operate ICN-DTNs during emergencies. Affected people and first responders use their mobile devices to specify their interests in particular content and/or application-specific functions that are then executed in the network on the fly, either partially or totally, in an opportunistic manner. Opportunistic named functions rely on user-defined interests and on locally optimal decisions based on battery lifetimes and device capabilities. In the presented emergency scenario, they are used to preprocess, analyze, integrate and transfer information extracted from images produced by smartphone cameras, with the aim of supporting the search for missing persons and the assessment of critical conditions in a disaster area. Experimental results show that opportunistic named functions reduce network congestion and improve battery lifetime in a network of battery-powered sensors, mobile devices, and mobile routers, while delivering crucial information to carry out situation analysis in disasters.","PeriodicalId":127096,"journal":{"name":"Proceedings of the 15th ACM International Conference on Computing Frontiers","volume":"253 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123683464","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}
