MULTI-SYMPLECTIC FOURIER PSEUDOSPECTRAL METHOD FOR A HIGHER ORDER WAVE EQUATION OF KDV TYPE

引用

Journal of Computational Mathematics 2015年第4期33卷 379-395页

作者： junjie wang Mathematics and Statistical Institute Pu Er University Pu Er 665000 China Mathematics Department of Northwest University Xidn 710127 China

The higher order wave equation of KdV type, which describes many important physical phenomena, has been investigated widely in last several decades. In this work, multi- symplectic formulations for the higher order wave equation of KdV type are presented, and the local conservation laws are shown to correspond to certain well-known Hamiltonian functionals. The multi-symplectic discretization of each formulation is calculated by the multi-symplectic Fourier pseudospectral scheme. Numerical experiments are carried out, which verify the efficiency of the Fourier pseudospectral method.

在小数据集上从零开始训练时,视觉Transformer无法与同规模的卷积神经网络媲美。基于图像的局部注意力方法,可以显著提高ViT的数据效率,但是会丢失距离较远但相关的补丁之间的信息。为了解决上述问题,提出一种双向并行局部注意力视觉Transformer的方法。该方法首先在特征层面上对补丁进行分组,在组内执行局部注意力,以利用特征空间中补丁之间的关系弥补信息丢失。其次,为了有效融合补丁之间的信息,将基于语义的局部注意力和基于图像的局部注意力并行结合起来,通过双向自适应学习来增强ViT模型在小数据上的性能。实验结果表明,该方法在计算量为15.2 GFLOPs和参数量为57.2 M的情况下,分别在CIFAR-10和CIFAR-100数据集上实现了97.93%和85.80%的准确性。相比于其他方法,双向并行局部注意力视觉Transformer在增强局部引导能力的同时,保持了局部注意力所需属性的有效性。

A Cross-Domain Ontology Semantic Representation Based on NCBI-BlueBERT Embedding

引用

Chinese Journal of Electronics 2022年第5期31卷 860-869页

作者： ZHAO Lingling wang junjie wang Chunyu GUO Maozu Faculty of Computing Harbin Institute of Technology Department of Medical Informatics School of Biomedical Engineering and InformaticsNanjing Medical University Beijing Key Laboratory of Intelligent Processing for Building Big Data School of Electrical and Information Engineering Beijing University of Civil Engineering and Architecture

A common but critical task in biological ontologies data analysis is to compare the difference between ontologies. There have been numerous ontologybased semantic-similarity measures proposed in specific ontology domain, but it still remains a challenge for crossdomain ontologies comparison. An ontology contains the scientific natural language description for the corresponding biological aspect. Therefore, we develop a new method based on natural language processing(NLP) representation model bidirectional encoder representations from transformers(BERT) for cross-domain semantic representation of biological ontologies. This article uses the BERT model to represent the word-level of the ontologies as a set of vectors, facilitating the semantic analysis or comparing the biomedical entities named in an ontology or associated with ontology terms. We evaluated the ability of our method in two experiments: calculating similarities of pair-wise disease ontology and human phenotype ontology terms and predicting the pair-wise of proteins interaction. The experimental results demonstrated the comparative performance. This gives promise to the development of NLP methods in biological data analysis.
