    This report gives an overview of the literature on decision tables over the past 15 years. As much as possible, for each reference, an author supplied abstract, a number of keywords and a classification are provided. In some cases own comments are added. The purpose of these comments is to show where, how and why decision tables are used. The literature is classified according to application area, theoretical versus practical character, year of publication, country or origin (not necessarily country of publication) and the language of the document. After a description of the scope of the interview, classification results and the classification by topic are presented. The main body of the paper is the ordered list of publications with abstract, classification and comments.

    Persistent Homology of Attractors For Action Recognition

    Full text link
    In this paper, we propose a novel framework for dynamical analysis of human actions from 3D motion capture data using topological data analysis. We model human actions using the topological features of the attractor of the dynamical system. We reconstruct the phase-space of time series corresponding to actions using time-delay embedding, and compute the persistent homology of the phase-space reconstruction. In order to better represent the topological properties of the phase-space, we incorporate the temporal adjacency information when computing the homology groups. The persistence of these homology groups encoded using persistence diagrams are used as features for the actions. Our experiments with action recognition using these features demonstrate that the proposed approach outperforms other baseline methods.Comment: 5 pages, Under review in International Conference on Image Processin

    The aptness of tangible user interfaces for explaining abstract computer network principles

    The technological deployment of Tangible User Interfaces (TUI) with their intrinsic ability to interlink the physical and digital domains, have steadily gained interest within the educational sector. As a concrete example of Reality Based Interaction, such digital manipulatives have been successfully implemented in the past years to introduce scientific and engineering concepts at earlier stages throughout the educational cycle. With difference to literature, this research investigates the suitability and effectiveness of implementing a TUI system to enhance the learning experience in a higher education environment. The proposal targets the understanding of advanced computer networking principles by the deployment of an interactive table-top system. Beyond the mere simulation and modelling of networking topologies, the design presents students the ability to directly interact with and visualise the protocol execution, hence augmenting their ability to understand the abstract nature of such algorithms. Following deployment of the proposed innovate prototype within the delivery of a university undergraduate programme, the quantitative effectiveness of this novel methodology will be assessed from both a teaching and learning perspective on its ability to convey the abstract notions of computer network principles

    ImageNet Large Scale Visual Recognition Challenge

    The ImageNet Large Scale Visual Recognition Challenge is a benchmark in object category classification and detection on hundreds of object categories and millions of images. The challenge has been run annually from 2010 to present, attracting participation from more than fifty institutions. This paper describes the creation of this benchmark dataset and the advances in object recognition that have been possible as a result. We discuss the challenges of collecting large-scale ground truth annotation, highlight key breakthroughs in categorical object recognition, provide a detailed analysis of the current state of the field of large-scale image classification and object detection, and compare the state-of-the-art computer vision accuracy with human accuracy. We conclude with lessons learned in the five years of the challenge, and propose future directions and improvements.Comment: 43 pages, 16 figures. v3 includes additional comparisons with PASCAL VOC (per-category comparisons in Table 3, distribution of localization difficulty in Fig 16), a list of queries used for obtaining object detection images (Appendix C), and some additional reference
