遗传算法主要借用生物进化中“适者生存”的规律。

遗传算法的适应度函数是用来区分群体中的个体好坏的标准。

遗传算法中起核心作用的是变异算子。

遗传算法采用群体搜索策略,同时对搜索空间中的多个解进行评估,因此遗传算法具有较好的全局搜索性能。

遗传算法能够保证每次都得到全局最优解。

生物进化过程中选择通过遗传和变异起作用,同时又使变异和遗传向着适应环境方向发展。

生物进化过程中遗传控制变异与选择的方向,变异为选择提供资料,遗传巩固与积累选择的资料。

在遗传算法中,将所有妨碍适应度值高的个体产生,从而影响遗传算常工作的问题统称为欺骗问题。

在遗传算法应用中,适应度函数的设计要结合问题本身的要求而定,但适应度函数和问题的目标函数没有关系。

在遗传算法中,适应度大的个体被选择的概率大,但不是说一定能够被选上。

遗传算法虚拟仿真实验和a星虚拟仿真实验是同一个软件系统,如果前面已经下载安装过,本次虚拟仿真实验就不需要再重新安装了。如果没有安装过,请先下载安装,然后根据实验要求(见附件),记录实验结果,完成结果分析,总结心得体会。

关于离散型hopfield神经网络的稳定性,下面叙述正确的是( )

hopfield神经网络用于联想记忆时,网络的记忆容量与( )有关

实现hopfield神经网络联想记忆的关键是网络到达记忆样本能量函数极小点时,确定网络的神经元间连接权值和阈值等参数。

如果将hopfield神经网络的稳态作为一个优化问题的目标函数极小点,那么初态朝稳态的收敛过程就是优化计算的过程。

卷积神经网络是一个全连接的神经网络,中间隐层通常包含多个卷积层。

卷积是一种有效提取图片特征的方法。一般用一个正方形卷积核,遍历图片上的每一个像素点。图片与卷积核重合区域内相对应的每一个像素值乘卷积核内相对应点的权重,然后求和,再加上偏置后,最后得到输出图片中的一个像素值。

卷积神经网络中,对不同位置的特征进行聚合统计,称为池化 (pooling)。池化不会丢失图像的信息,也不会降低其空间分辨率。

胶囊网络是由胶囊组成的,一个胶囊就是一个神经元。

胶囊网络中,胶囊会学习检测给定区域(例如一个矩形)图像的特定目标,它输出一个向量(例如一个八维向量),向量的长度代表目标存在的概率估计。

生成对抗网络(gan)在训练过程中,生成网络g的目标就是尽量生成真实的图片去欺骗判别网络d。而d的目标就是尽量辨别出g生成的假图像和真实的图像。这样,g和d构成了一个动态的“博弈过程”,最终的平衡点即纳什均衡点。
