| 1 | 一种新型的局部连接BP网络模型及应用显示文摘局部连接神经网络简化了网络结构,提升了网络收敛速度和减少了网络训练复杂度,可用于函数逼近和系统建模.为了采用直观的建模方式对实际系统网络拓扑逼近,对此文章提出一种新型的局部连接BP网络模型(local BP neural network,LBPNN).该模型的网络结构可以模拟任意前馈型网络拓扑结构,其网络模型中的连接权和神经元与被模拟的网络拓扑中的边和节点一一对应.传统带约束的非线性规划和智能优化算法,其参数辨识受限条件多和算法代价较大,同时提出了与LBPNN模型相应的一种新型的带约束的随机梯度下降法(constrained stochastic gradient descent,CSGD)对其权值参数进行训练.通过算例仿真验证了CSGD训练算法的有效性,稳定性和鲁棒性. | 钱坤 王天真 马斌 汤天浩 CLARAMUNT Christophe | 2014 | 系统科学与数学2014,34,7: | 3 |

| 3 | 基于灰色预测的粒子滤波算法显示文摘针对标准粒子滤波(SPF)算法在目标机动时跟踪滤波性能不高的问题,引入灰色预测理论,提出了一种基于灰色预测的粒子滤波(PFGF)算法,给出了算法的具体描述和运算流程。当预先建立的状态模型不再适用于目标的真实运动状态时,该方法具有良好的预估性能,减少了对事先假定目标状态模型的依赖性。与SPF方法进行了蒙特卡洛仿真比较分析,实验结果证明,PFGF算法在不增加计算复杂度的情况下,提高了跟踪精度,能够很好地克服粒子退化现象。 | 王天真 汤天浩 张圣杰 Christophe Claramunt | 2012 | 高技术通讯2012,22,4: | 2 |

| 5 | A graph-based approach for the structural analysis of road and building layouts显示文摘A better understanding of the relationship between the structure and functions of urban and suburban spaces is one of the avenues of research still open for geographical information science.The research presented in this paper develops several graph-based metrics whose objective is to characterize some local and global structural properties that reflect the way the overall building layout can be cross-related to the one of the road layout.Such structural properties are modeled as an aggregation of parcels,buildings,and road networks.We introduce several computational measures(Ratio Minimum Distance,Minimum Ratio Minimum Distance,and Metric Compactness)that respectively evaluate the capability for a given road to be connected with the whole road network.These measures reveal emerging sub-network structures and point out differences between less-connective and moreconnective parts of the network.Based on these local and global properties derived from the topological and graph-based representation,and on building density metrics,this paper proposes an analysis of road and building layouts at different levels of granularity.The metrics developed are applied to a case study in which the derived properties reveal coherent as well as incoherent neighborhoods that illustrate the potential of the approach and the way buildings and roads can be relatively connected in a given urban environment.Overall,and by integrating the parcels and buildings layouts,this approach complements other previous and related works that mainly retain the configurational structure of the urban network as well as morphological studies whose focus is generally limited to the analysis of the building layout. | Mathieu Domingo Rémy Thibaud Christophe Claramunt | 2019 | Geo-Spatial Information Science2019,22,1: | 2 |
