Webed using effective hierarchical random walk networks, denot-ed as HRWN. The proposed HRWN jointly optimizes dual-tunnel CNN, pixelwise afnity and seeds map via a novel random walk layer, which enforces spatial consistency in the deepest layers of the network. In designed random walk lay-er, the predicted distribution of dual-tunnel CNN serves as Web9 de abr. de 2024 · A hierarchical graph is a kind of self-similar network, which is widely discussed and has a wide range of applications. In this paper, we introduce a class of weighted hierarchical graphs H (n, k), which is constructed using the hierarchical product of complete graphs. The weighted hierarchical graph depends on two parameters: the …
Web19 de fev. de 2014 · Public transit plays a key role in shaping the transportation structure of large and fast growing cities. To cope with high population and employment density, such cities usually resort to multi-modal transit services, such as rail, BRT and bus. These modes are strategically connected to form an effective transit network. Among the transit modes, … WebIn this paper, we develop two analytic models for the performance analysis of HMIPv6 in IP-based cellular networks, which are based on the random-walk and the fluid-flow models. Based on these analytic models, we formulate the …
