  1. Some new ideas are proposed in this thesis based on svm and ica : firstly, a modified svm method based on posteriori probability theory is given, which makes the classification super plane corrected from the original one. a better classification result is obtained without finding the best quadric optimization algorithm and large scale training datasets are reduced to small scale training datasets at the same time. secondly, ica is applied to the preprocessing period of the recognition character images for purpose of feature extraction and dimension reduction

    本文在系統研究svm和ica的基礎上提出了以下新的觀:其一是採用了引入后驗概率的修正svm方法,它在原分類超平面的基礎上不斷修正分類超平面,提高分類正確率,從而避免了尋找最優二次規劃的煩,同時將大規模訓練樣本集化為小規模訓練樣本集;其二是應用獨立分量分析ica對需要進行識別的字元預處理,提取字元特徵,降低輸入數據的維數,從而可以為下一步的svm識別過程提供好的數據集,用以提高識別率和識別速度。
