Lately, skeleton-based action recognition has drawn remarkable attention to graph convolutional networks (GCNs). Recent methods have focused on learning because topology is the key GCNs. We propose align channel level by introducing convolution with enriched based careful channel-wise correlations, namely attentive correlation (ACC-GC). For model learn topologies, ACC-GC learns a shared spanning many channels and enhances it correlations. Encoding intra-correlation between various nodes...

Reaching a flat network is the main target of future evolved packet core for 5G mobile networks. The current 4th generation centralized architecture, including Serving Gateway and Packet-data-network Gateway; both act as mobility IP anchors. However, this architecture suffers from non-optimal routing intolerable latency due to many control messages. To overcome these challenges, we propose partially distributed 5th networks, such that plane data are fully decoupled. proposed based on node...

Enhancing the performance of wireless networks and communication systems requires careful resource allocation. Resource allocation optimization, however, is regarded as a mixed-integer non-linear programming (MINLP) problem, which NP-hard non-convex. Due to serious limitations conventional procedures, solving such optimization problems specialized approaches. For instance, no optimal can be guaranteed using heuristic algorithms; besides, global suffer from exponential computation complexity...
