The core idea of ELM is to initialize the connection weights between the input layer to the hidden layer randomly. Then through parsing, the connection weights between the output layer to the hidden layer are quickly calculated, and a simple and efficient neural network model is constructed by randomly generating the input weights and the bias of the hidden layer neurons.
Compared with traditional neural network algorithms, ELM is characterized by fast training ...

WiMi took DCNN as the base model for image recognition. By training on a large amount of well-labeled image data, the network is allowed to learn the feature representations of different objects and accurately locate and recognize these objects in the input image. In order to accommodate the processing of dynamic images, WiMi adapted the network appropriately for information transfer and tracking between successive frames. Then, the recognized objects are combine...

As IoT applications continue to expand, traditional security models may not be able to meet the challenges of future digitalization needs.  
First, it is necessary to ensure that the communication between nodes is secure against threats such as attacks. Secondly, it is necessary to address the risk of privacy leakage that a large amount of user data may suffer when it is transmitted in the network. Most importantly, to realize all of this in an IoT architecture,...
