模块化钢结构建筑平面布局方案智能生成式设计方法

Jianzhu Gangjiegou Jinzhan
为研究模块化钢结构建筑平面布局方案的智能生成式设计方法，分别基于平面可行域的有限离散化、不同的变量定义方法、约束条件和目标函数，形成了多目标非线性约束整数规划问题和线性整数规划问题，并分别提出了基于遗传算法和平面密铺算法的求解方法。通过一例基于L形平面可行域的数值算例，阐释了所提出方法的可行性和有效性。数值算例结果表明，在相同目标函数下的模块化钢结构建筑布局方案最优解不唯一；基于遗传算法的智能生成式方法可在较小的计算代价下得到较优的可行解，并可为模块单元尺寸的选型提供依据 ...

模糊遗传人工神经网络算法提取乳腺微钙化点的效果

Zhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】微钙化点是早期乳腺癌的重要征象之一，本研究联合运用遗传算法、模糊数学和人工神经网络，建议一种乳腺微钙化点提取的新方法，为乳腺病变的自动识别提供前期处理，为早期乳腺癌的临床诊断提供帮助。【方法】首先利用随机方法产生大量的样本，然后，利用模糊遗传算法对产生的随机样本进行分类，将分类后的样本输入人工神经网络进行训练，将310幅乳腺图像的感兴趣区域输入训练后的人工神经网络分类器进行分类。【结果】与微钙化点提取方面的同类文献相比较，结果表明该算法在相同误检率下得到较高的阳性检出率。【结论 ...
