  • Edge-centric delegation of authorization for constrained devices in the Internet of Things
    Comput. Commun. (IF 2.816) Pub Date : 2020-06-29
    Elías Grande; Marta Beltrán

    Access management poses a significant challenge within the Internet of Things (IoT) given the constrained capabilities in terms of computing, memory, storage, bandwidth and energy available for most of the low-cost devices and things embedded in the physical world. In this scenario, Edge Computing can be considered a powerful opportunity to solve authorization issues, deploying edge devices near IoT

    Pattern Recogn. Lett. (IF 3.255) Pub Date : 2020-06-30
    Arnu Pretorius; Herman Kamper; Steve Kroon

    Recent work has established the equivalence between deep neural networks and Gaussian processes (GPs), resulting in so-called neural network Gaussian processes (NNGPs). The behaviour of these models depends on the initialisation of the corresponding network. In this work, we consider the impact of noise regularisation (e.g. dropout) on NNGPs, and relate their behaviour to signal propagation theory

    Michael A. Henning, Arti Pandey, Vikash Tripathi

    For a graph G = (V, E) with no isolated vertices, a set \(D\subseteq V\) is called a semipaired dominating set of G if (i)D is a dominating set of G, and (ii)D can be partitioned into two element subsets such that the vertices in each two element set are at distance at most two. The minimum cardinality of a semipaired dominating set of G is called the semipaired domination number of G, and is denoted

    The rapid increase in the number of cores on chips forced the designers to invent new communication methods such as Network-on-Chip (NoC) paradigm. Advances in integrated circuit fabrications even allowed three-dimensional NoC (3D-NoC) implementations. 3D-NoCs have more advantages than their 2D counterparts such as lower area, higher throughput, better performance, and less energy consumption. However

    NOA-AID (Network Overlays for Adaptive information Aggregation, Indexing and Discovery on the fog) is an approach for decentralized indexing, aggregation and discovery of data belonging to streams. It is organized on two network layers. The upper layer is in charge of delivering an information discovery approach by providing a distributed index structure. The lower layer is devoted to resource aggregation

  • Algebraic models of simple type theories: a polynomial approach
    arXiv.cs.LO Pub Date : 2020-06-30
    Nathanael Arkor; Marcelo Fiore

    We develop algebraic models of simple type theories, laying out a framework that extends universal algebra to incorporate both algebraic sorting and variable binding. Examples of simple type theories include the unityped and simply-typed $\lambda$-calculi, the computational $\lambda$-calculus, and predicate logic. Simple type theories are given models in presheaf categories, with structure specified

  • It's Time to Play Safe: Shield Synthesis for Timed Systems
    arXiv.cs.LO Pub Date : 2020-06-30
    Roderick Bloem; Peter Gjøl Jensen; Bettina Könighofer; Kim Guldstrand Larsen; Florian Lorber; Alexander Palmisano

    Erroneous behaviour in safety critical real-time systems may inflict serious consequences. In this paper, we show how to synthesize timed shields from timed safety properties given as timed automata. A timed shield enforces the safety of a running system while interfering with the system as little as possible. We present timed post-shields and timed pre-shields. A timed pre-shield is placed before

  • Neural Datalog Through Time: Informed Temporal Modeling via Logical Specification
    arXiv.cs.LO Pub Date : 2020-06-30
    Hongyuan Mei; Guanghui Qin; Minjie Xu; Jason Eisner

    Learning how to predict future events from patterns of past events is difficult when the set of possible event types is large. Training an unrestricted neural model might overfit to spurious patterns. To exploit domain-specific knowledge of how past events might affect an event's present probability, we propose using a temporal deductive database to track structured facts over time. Rules serve to

  • Frege's theory of types
    arXiv.cs.LO Pub Date : 2020-06-30
    Bruno Bentzen

    There is a widespread assumption in type theory that the discipline begins with Russell's efforts to resolve paradoxes concerning the naive notion of a class. My aim in this paper is to argue that Frege's sharp distinction between terms denoting objects and terms denoting functions on the basis of their saturation anticipate a simple type theory, although Frege vacillates between regarding functions

    In this paper, I revisit Frege's theory of sense and reference in the constructive setting of the meaning explanations of type theory, extending and sharpening a program--value analysis of sense and reference proposed by Martin-L\"of building on previous work of Dummett. I propose a computational identity criterion for senses and argue that it validates what I see as the most plausible interpretation

    In a computing context, cybersecurity is undergoing massive shifts in technology and its operations in recent days, and data science is driving the change. Extracting security incident patterns or insights from cybersecurity data and building corresponding data-driven model, is the key to make a security system automated and intelligent. To understand and analyze the actual phenomena with data, various

    The use of quantum computing in graph community detection and regularity checking related to Szemeredi's Regularity Lemma (SRL) are demonstrated with D-Wave Systems' quantum annealer and simulations. We demonstrate the capability of quantum computing in solving hard problems relevant to big data. A new community detection algorithm based on SRL is also introduced and tested.

  • A Compact Gated-Synapse Model for Neuromorphic Circuits
    arXiv.cs.ET Pub Date : 2020-06-29
    Alexander Jones; Rashmi Jha

    This work reports a compact behavioral model for gated-synaptic memory. The model is developed in Verilog-A for easy integration into computer-aided design of neuromorphic circuits using emerging memory. The model encompasses various forms of gated synapses within a single framework and is not restricted to only a single type. The behavioral theory of the model is described in detail along with a full
