Abstract Intrusion detection represents an efficacious approach for addressing security concerns. However, given the substantial volume and high-dimensional nature of WLAN dataset features, existing methods exhibit limited effectiveness in feature extraction, thereby impacting classification performance. To address above problems, improved deep neural network (DNN) model intrusion was proposed. Firstly, activation function loss a single sparse autoencoders (SAE) were determined through...
Abstract. Enterprises are the basis of urban economic development and an essential factor that affects structure. It is great significance to study spatiotemporal distribution enterprises benefit cities planning development. Based on registration data Administrator for Industry Commerce Wuhan from 1996 2007, in this paper, we analysed city. We divided into 2,356 square grids with a length 2 km counted number different industry categories each grid. Then calculated aggregation intensity index...
Abstract. Ripley’s K functions are powerful tools for studying the spatial arrangement or spatiotemporal distribution characteristics of geographic phenomena and events in analysis has been used many fields. However, compute-intensive point-wise distance comparisons, edge correction simulations significance test. Although parallel computing technologies have adopted to accelerate functions, previous works haven’t extended optimization from space space-time dimension. This study presents an...
