Embodiment Construction
[0053] The method of the invention uses immune clone selection optimization as a basic search algorithm, uses dynamic neighborhood information to guide the search of a Gaussian mixture model during the search process, and finally obtains a Gaussian mixture model that can better express data characteristics.
[0054] The immune clone selection algorithm is a simulation of the immune clone selection mechanism of organisms, so it is a swarm intelligence algorithm. In this algorithm, the antigen represents the problem to be solved, the antibody represents the solution of the problem, and the fitness function is used to evaluate the quality of the solution. In the present invention, an immune clone selection algorithm is used to search for a Gaussian mixture model. Antigens, antibodies, and fitness functions are thus represented as follows: antigens are the detected or segmented datasets, and antibodies are represented as a Gaussian mixture model (i.e. ), the fitness function is ...
