A novel neural network with chaotic property is proposed. The network is composed by different neurons. Some activation function is chaotic iterative function instead of the conventional Sigmoid function. In the process of learning, taking advantage of the randomicity property and ergodicity property of chaos, the generalization capability and the optimizing efficiency can be improved. The simulation...
For a kind of weak harmonic wave signal in chaotic noise, this paper proposes a new blind identify algorithm which based on generalized regression neural network (GRNN) to estimate parameters of chaotic system, and then apply reiteration blind deconvolution method to remove remains noise in the system, and extract weak signal from chaotic background. From 2597 observation points, we obtain mean deviation...
Influenced by detector materials' non-uniformity, growth and etching techniques' etc, every detector's responsivity of infrared focal plane arrays (IRFPA) is different, which results in non-uniformity of IRFPA. And non-uniformity of IRFPA generates fixed pattern noises (FPN) that are superposed on infrared images. So the quality of infrared images is poor, which greatly limited the application of...
