The recommendation system based on knowledge graph assistance has more advantages than the traditional recommendation system, mainly reflected in: accurate, efficient and explainable. Most of the recommendation methods of existing studies use knowledge graph representation learning for information mining of entity features, but some of them ignore the neighborhood information of knowledge graph entities, resulting in the loss of high-order feature information. Considering the above problem, this study proposes a recommendation method based on graph neural network for the problem that the existing recommendation methods ignore the overall information in the process of knowledge graph entity information mining. The graph attention network is introduced to carry out neighborhood information aggregation to make up for the neighborhood information of missing entities in the process of extracting the features of the knowledge graph in existing research. In this study, the prediction experiments of click rate and top-k recommendation scenarios were carried out on the data under the four backgrounds of movies, books, online courses and music, and the influence of some key parameters and structures in the model on the model was analyzed, compared and discussed. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Lithology identification serves as a crucial foundation for the precise exploration and safe exploitation of geological resources. However, challenges arise from the inherent imbalance and overlap present in logging data, making the accurate identification of lithology a complex task. Addressing these challenges effectively, this paper introduces a novel algorithm, the Error Correcting Output Code algorithm based on Hierarchical Clustering(HC-ECOC). The proposed algorithm initially formulates a coding matrix using distance and overlap measures between class clusters. Subsequently, it extends the length of the coding matrix by considering both the accuracy of the integrated classifier and the diversity among base classifiers. To evaluate the efficacy of the proposed method, comparisons were conducted with alternative algorithms using UCI datasets and an authentic lithology dataset. The results unequivocally demonstrate the superior performance of our algorithm. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

Recent advancements in Novel View Synthesis using neural radiance fields and 3D Gaussian splatting have demonstrated promising results. However, these methods conventionally rely on accurate initial poses and point clouds from the model of structure from motion, which poses challenges in sparse input views. To addressing these drawbacks, we introduces an novel method for view synthesis based on 3D Gaussian splatting. Our approach operates on sparse input views without the prerequisite of pose priors, achieving reconstruction and real-time rendering of novel perspectives. For the deficiency of camera poses and point cloud, we employ an end-to-end deep learning model to recover the 3D structure from a few of 2D images to initialize the 3D Gaussian point cloud. In addressing the issue with few-shot, we utilize the differentiable rasterization module to render depth map and apply regulation on it. Additionally, we incorporate supervision between input views by interpolating to generate novel perspectives during training. Experimental results demonstrate that our proposed method significantly enhances the capabilities of 3D Gaussian splatting for novel view synthesis in sparse views and without the necessity of camera pose priors. © 2024 IEEE.

Developing improved measures of non-Gaussianity and Gaussianity for quantum states based on normalized Hilbert–Schmidt distance

Non-Gaussianity of quantum states is a very important source for quantum information technology and can be quantified by using the known squared Hilbert–Schmidt distance recently introduced by Genoni et al.(Phys. Rev. A 78 042327(2007)). It is, however, shown that such a measure has many imperfects such as the lack of the swapping symmetry and the ineffectiveness evaluation of even Schr?dinger-cat-like states with small amplitudes. To deal with these difficulties, we propose an improved measure of non-Gaussianity for quantum states and discuss its properties in detail. We then exploit this improved measure to evaluate the non-Gaussianities of some relevant single-mode non-Gaussian states and multi-mode non-Gaussian entangled states. These results show that our measure is reliable. We also introduce a modified measure for Gaussianity following Mandilara and Cerf(Phys. Rev. A 86 030102(R)(2012)) and establish a conservation relation of non-Gaussianity and Gaussianity of a quantum state.

Threshold selection for thresholding segmentation methods is a critical issue in vision-based detection of surface mount devices (SMDs). The thresholds in actual industrial equipments rely on manual adjustment in SMDs applications, which depends on the experience and ability of an operator. We propose a novel method based Q-Learning to automatically learn the threshold using a segmentation metric instead of manual adjustment, making the threshold adjustment process more intelligent. This framework regards 256 thresholds as state sets. A threshold list with a reasonable step is selected as actions set simulating an operator's threshold adjustment process. The metric difference of SMDs before and after threshold adjustment forms the reward/punishment of Q-Learning framework. Finally, a new strategy that determines the search direction according to previous reward is proposed to improve search efficiency. We conducted experiments on different chips and lights, and the results show that the proposed Q-Learning method performed better on search efficiency and segmentation than the traditional methods. © 2023 IEEE.

Among the MEMS gyroscopes, MEMS disk gyroscopes exhibit high performance potential and broad development prospects. However, due to the small mass and detection capacitance of the MEMS gyroscopes, the detection sensitivity and the signal-to-noise ratio of the gyroscope are low. Moreover, the structural coupling and errors introduced by the manufacturing processing errors of the gyroscope can interfere with the angular rate detection. Parametric excitation is proposed as a kind of excitation scheme, involving periodic modulation of stiffness, which can effectively improve the quality factor and enhance the detection sensitivity and signal-to-noise ratio of gyroscope. Therefore, this dissertation takes the independently designed MEMS disk gyroscope as the object, and proposes and establishes the dual-modal parametric excitation dynamic equations of stiffness coupling and damping coupling. Based on the above analysis, a dual-modal parametric excitation control system for the MEMS disk resonator gyroscope is established, and the influence of parametric excitation on the drive signal and the sense mode is verified. Compared with the open-loop detection and control scheme without parametric excitation, the main performance of the gyroscope has been significantly improved, including a 6.4-fold increase in the quality factor amplification gain for the drive mode, a 4.9 -fold improvement in open-loop detection sensitivity, and a 2.5-fold enhancement of bias instability. The bias instability is increased from 20.18/h to 8.04/*** angle random walk is increased from 1.65/h to 0.59/h © 2024 IEEE.
