Joint Communication and Inference User Allocation in LLM Native Networks
No full textLarge language models (LLMs) are game changers for future next-generation networks, unlocking new opportunities for disruptive and interactive services and applications. Edge computing enables deployment of LLMs closer to the users, allowing for the implementation of highly responsive intelligent systems. This paper proposes a matching theory-based algorithm to optimize the user-LLM association and considers both the communication and inference delay, in the presence of capacity-constrained edge nodes. The objective is to minimize end-to-end user delay, that is, the time elapsed between when a user submits a request and when the response is sent back. Therefore, a matching game is formulated between the users and the LLMs, assuming heterogeneous LLMs, specialized in different types of learning tasks. The scenario is modeled as a matching game with externalities and incomplete lists, which terminates in a stable configuration, leveraging monotonic user preference list metric, within the algorithm execution. A comparative performance evaluation against different state-of-the-art techniques confirms the advantages of adopting a joint communication and inference aware approach to orchestrate the user-LLM assignments
Virtual Functions Placement with Time Constraints in Fog Computing: a Matching Theory Perspective
Full text linkThis paper proposes two virtual function (VFs) placement approaches in a Fog domain. The considered solutions formulate a matching game with externalities, aiming at minimizing both the worst application completion time and the number of applications in outage, i.e., the number of applications with an overall completion time greater than a given deadline. The first proposed matching game is established between the VFs set and the Fog Nodes (FNs) set by taking into account the ordered sequence of services (i.e., chain) requested by each application. Conversely, the second proposed method overlooks the applications service chain structure in formulating the VF placement problem, with the aim at lowering the computation complexity without loosing the performance. Furthermore, in order to complete our analysis, the stability of the reached matchings has been theoretically proved for both the proposed solutions. Finally, performance comparisons of the proposed MT approaches with different alternatives are provided to highlight the superior performance of the proposed methods
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
An Efficient Resource Allocation Scheme for Applications in LR-WPANs based on a Stable Matching with Externalities Approach
No full textThis paper deals with an efficient resource allocation algorithm for Wide-Area Low Rate Wireless Personal Area Networks (LR-WPANs), based on the IEEE 802.15.4m standard.
The proposed scheme aims at lowering the spectrum congestion problems and optimizing performance in terms of data packets dropping probability for all the active clusters of end-devices.
The algorithm realizes a many-to-one mapping between the sets of LR-WPANs and available access bands (i.e., TV white space bands). It is based on a matching game with externalities
and involves two-side preferences, i.e., clusters over bands and bands over clusters, respectively. The procedure provides high resource reuse, adaptation to changes of system conditions,
and improvements on quality of service. Furthermore, a postmatching procedure is also discussed to ensure stability of the provided many-to-one matching. Finally, the good behavior of
the matching approach is validated by providing performance comparisons with alternative schemes based on the random assignment, the Brelaz graph coloring algorithm applied in a
modified form and potential game strategy
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
