چکیده
Understanding the interconnected relationships of large-scale information networks like social, scholar and Internet Things is vital for tasks recommendation fraud detection. The vast majority real-world are inherently heterogeneous dynamic, containing many different types nodes edges can change drastically over time. dynamicity heterogeneity make it extremely challenging to reason about network structure. Unfortunately, existing approaches inadequate in modeling real-life dynamical as they either have strong assumption a given stochastic process or fail capture structure, all require extensive computational resources. We introduce Lime , better approach dynamic networks. designed extract high-quality representation with significantly lower memory resources time state-of-the-arts. Unlike prior work that uses vector encode each node, we exploit semantic among multiple similar semantics shared vectors. By using fewer node vectors, our reduces required space encoding To effectively trade sharing reduced footprint, employ recursive neural (RsNN) carefully optimization strategies explore novel cuboid space. then go further by showing, first time, how an effective incremental learning be developed – help RsNN, set techniques allow framework quickly efficiently adapt constantly evolving network. evaluate applying three representative network-based tasks, classification, clustering anomaly detection, performing on datasets. compare against eleven state-of-the-art representation. Our experiments demonstrate not only footprint 80 percent processing 2x when but also delivers comparable performance downstream tasks. show method boost up 20x without compromising quality learned

On the effect of low-quality node observation on learning over incremental adaptive networks
In this paper, we study the impact of low-quality node on the performance of incremental least mean square (ILMS) adaptive networks. Adaptive networks involve many nodes with adaptation and learning capabilities. Low-quality mode in the performance of a node in a practical sensor network is modeled by the observation of pure noise (its observation noise) that leads to an unreliable measurement....
متن کاملDistributed Incremental Least Mean-Square for Parameter Estimation using Heterogeneous Adaptive Networks in Unreliable Measurements
Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...
متن کاملFabrication of low cost in-house slab homogeneous and heterogeneous phantoms for lung radiation treatment
Background: The heterogeneous composition of the human body presents numerous tissue types and cavities with widely differing radiologic properties. The aim of the present work was to develop a low cost homogeneous and heterogeneous phantom and the absorbed dose were measured by ionization chamber for different radiotherapy treatment techniques and compared with treatment planning syst...
متن کاملFarmLime: Low-cost lime for small-scale farming
In the less developed parts of southern Africa, where agriculture is crucial in daily survival, agricultural lime is often difficult to obtain. This is due to the scarcity of production sites, high transport costs and inadequate support for farmers from government extension services. In Zambia there are upwards of 700,000 small-scale farmers who struggle to farm on acid soils and as a result ha...
متن کاملdynamic investment model under heterogeneous information and probability beliefs:
since the rate of return on different opportunities for investment is random, the optimal distribution of ones capital is put foreward as a stochastic control problem. in this paper, using modem techniques in the theory of random functions and the stochsatic calculus, the problem is discussed for the case when the information possessed by the different investors, as well as their probability be...
