Accordingly, a deep learning architecture (denoted as MSA-UITC) is proposed for the target microblog. Firstly, the coevolution of emotional contagion and behavior is described by the tie strength between microblogs, that is, with the spread of emotional contagion, user behavior such as emotional expression will be affected. Then, based on user interaction and the correlation with target microblog, the Hawkes process is adopted to quantify the tie strength between microblogs so as to build the corresponding weighted network. Secondly, in the weighted network, the Deepwalk algorithm is used to build the sequence representation of microblogs which are similar to the target microblog. Next, a CNN-BiLSTM-Attention network (the convolutional neural network and bidirectional long short-term memory network with a multihead attention mechanism) is designed to analyze the sentiment ana...

The constituent recursive systematic convolutional (RSC) codes in turbo codes are more structural and this lends the encoding problem easier with a shift-register circuit. While the encoding of LDPC codes is performed via matrix multiplication, and this is more complex than it

After a detailed analysis of its principle and design, a complete FOG signal detection system is developed and set-up. Experiments and tests show that the scheme can solve problems such as scale factor error and dynamic range effectively.

They can be viewed as special kinds of LDPC codes in the way their parity-check matrix are sparse. Like LDPC codes, they can be decoded using the messages-passing algorithm efficiently, while the existence of short length circles in their corresponding factor graph representation has a deleterious effect
