  1. However, some of face recognition problems still require further development, this is the case for problems of recognition face images conveying changes in illumination, facial expression and changes due to the time delay between the acquistion of the reference and tested face images. our main work is to analysis methods of extraction face features and contraction of classifier. the work presented in this paper is to apply self - organizing feature map and minor component to extraction features from multi - view face images, then combine those features as a new combined feature set, in order to reduce redundancy data, we apply clone algorithms to reduce data through rotation in input space

    我們改進了一種基於矩理論的識別方法,給出了計算公式和證明過程,可用於解決小規模人臉識別問題;我們將智能方法應用到人臉識別中,分別利用自組織特徵映射和次分量方法抽取人臉的整體特徵和局部特徵,依據特徵融合理論,重新組合為新的復合特徵,為壓縮特徵數據,我們首次引入克隆選擇演算法自動進行特徵優化選擇,最後,利用支持矢量機構造多分類器進行分類識別,在不同規模人臉識別庫上模擬結果表明,該系統自適應能力強,分類識別精度高,適用於大規模復雜人臉識別問題。
  2. We, in chapter 4, comprehensively discuss the dynamics of discrete chaotic neural networks, including f the existence of fixed points, the stable, unstable dynamics of the fixed point, the saddle - node and period doubling bifurcations in singie neuron model, and chaotic dynamics of the networks. the proofs and de - ductions involve schauder fixed point principle, constructions of lyapunov func - tions, bifurcation theory, contraction map principle, and anti - integrable limit method

    在本文的第四章中,我們首先介紹了離散混飩神經元、神經網路模型由來與具體的數學模型,依次給出了該離散神經網路的中不動點存在性與惟一性的分析:穩定性與不穩定性的分析;神經元模型的分枝分析;神經網路中馬羅陀意義下混3屯動力學的分析
