According to signal characteristic of Unified S-band (USB) measurement and control system, a method of spectrum sensing based on artificial neural network (ANN) is introduced in this paper. Spectrum sensing classifier is designed by the independent learning ability of ANN. The information collected by departed classifier is studied and stored to accurately judge that whether the master signal exists...
This paper proposes a new method of text categorization called the clonal selection algorithm based on antibody density (CSABAD). In this method, antigen, B cell and antibody are respectively corresponded with training texts, a possible individual of classifier and the affinity between the individual and training texts. B cells consist of general cells, fresh cells and memory cells. General cells...
The nature of immune algorithm is to distinguish between self and non-self. On the basis of immune algorithm, we propose a new method of text categorization called the Clonal Selection Algorithm Based on Antibody Density (CSABAD). According to the clonal selection principle and density control mechanism, only those cells that have higher affinity and lower density are selected to proliferate. The...
