| 摘 要： | 将遗传算法和神经网络结合应用于乳腺癌细胞分类，首先利用遗传算法随机提取训练集的属性特征，然后用提取特征后的训练集训练神经网络，最后得筑必要的特征子集优化网络结构，仿真实验结果表明，遗传神经网络不仅可以优化神经网络的权值和阈值，还能有效地找出线性可分离特征子集，从而达到降低数据维数并提高分类精度的目的。

| Abstract: | A genetic algorithm combined neural network with the application in breast cancer cells classification was proposed.The genetic algorithm was used randomly to extract features from training sets.The training sets with extracted features were used to train the neural network.The necessary attributes subsets were used to optimize network structure.The simulation results show that the proposed model can not only optimize the weights and thresholds of neural network,but also effectively find linear separable fe... |
