To select suitable knowledge graphs for use from many knowledge graphs, quality assessment is particularly important. As an important thing of quality assessment, completeness assessment generally refers to the ratio of the current data volume to the total data volume.When evaluating the completeness of a knowledge graph, it is often necessary to refine the completeness dimension by setting different completeness metrics to produce more complete and understandable evaluation results for the knowledge graph.However, lack of awareness of requirements is the most problematic quality issue. In the actual evaluation process, the existing completeness metrics need to consider the actual application. Therefore, to accurately recommend suitable knowledge graphs to many users, it is particularly important to develop relevant measurement metrics and formulate measurement schemes for completeness. In this paper, we will first clarify the concept of completeness, establish each metric of completeness, and finally design a measurement proposal for the completeness of knowledge graphs.展开更多

The geometric multiplicity and algebraic index of the eigenvalue are investigated. Furthermore, the algebraic multiplicity of the eigenvalue is obtained. Based on these properties, the concrete completeness formulation of the system of eigenvectors or root vectors of the Hamiltonian operator is proposed. It is shown that the completeness is determined by the system of eigenvectors of the operator entries. Finally, the applications of the results to some problems in the elasticity theory are presented.展开更多

Moreover, two constructions of resilient functions are provided, which have optimal degree of completeness, high nonlinearity, and high algebraic degree.展开更多

Roux & Bengio have proved that adding hidden units yield a strictly improved modeling power, and Restricted Boltzmann Machines (RBM) are universal approximators of discrete distributions. In this paper, we provide yet another proof. The advantage of this new proof is that it will lead to several new learning algorithms. We prove that the Deep Neural Networks implement an expansion and the expansion is complete. First, we briefly review the basic Boltzmann Machine and that the invariant distributions of the Boltzmann Machine generate Markov chains. We then review the θ-transformation and its completeness, i.e. any function can be expanded by θ-transformation. We further review ABM (Attrasoft Boltzmann Machine). The invariant distribution of the ABM is a θ-transformation;therefore, an ABM can simulate any distribution. We discuss how to convert an ABM into a Deep Neural Network. Finally, by establishing the equivalence between an ABM and the Deep Neural Network, we prove that the Deep Neural Network is complete.展开更多

We aimed to determine the rate of completeness and timeliness of hepatitis B vaccination among children under 15 years of age in Libreville. Methods: Cross-sectional study conducted over 9 months, including children randomly selected from vaccination centres, nurseries and kindergartens. We collected data on the child, socio-economic characteristics of the families, and dates of administration of hepatitis B vaccines. We determined the compliance of the vaccination dates according to the vaccination start pattern. Results: We included 453 children, of whom 236 were girls, for a sex ratio of 0.92. A total of 87% (95% CI [83.9% - 90.1%]) of children had started and completed their 3 doses of vaccine before the 12<sup>th</sup> month of age. 149 subjects had received their 3 doses on time according to the original vaccination schedule, i.e. 32.9% (95% CI [28.6% - 37.2%]). Factors significantly associated with completeness were vaccination in a public centre OR = 114 [47.2 - 347] p <sup>st</sup> dose OR = 3 [1.6 - 5.5] p < 0.001. Age at first dose was the predictor of timeliness aOR = 1.3 (95% CI [1.2 - 1.5] p 0.001). Conclusion: The respect for the vaccination deadlines is insufficient in our context, solutions exist to improve this situation.展开更多

It contains demographic details of the patient including full names, age and gender;the test required;location of the patient;date and time of request among other details. Incomplete and inaccurate filling of the request forms may cause errors which can impact on the quality of the patient care. Methodology: The study was a descriptive cross sectional where 289 laboratory request forms submitted consecutively to the haematology laboratory during the month of January 2018 were evaluated. Data was collected using a data collection form and analyzed by use of frequency table. Ethical clearance was sought from Institutional Research and Ethical Committee of Moi University and Moi Teaching and Referral Hospital. Results: Of all the 289 forms evaluated, only 1% (3/289) had all the required information. The parameters with the most information were patient’s name (100%), hospital number (100%), sex (99.7%), age (98.3%), investigation requested (97.6%), the location of the patient (96.9%), clinician’s name (96.9%) and signature (96.5%). The least information was recorded for clinical history (14.7%) and address of the patient (4.8%). Conclusion: The study showed that there were inadequacies in the recording of the required information in the laboratory request form. The parameters which were completely filled were the patient’s name and the hospital number, whereas the address and the clinical history had the least completion rates.展开更多
