所谓的分类问题就是指对于相同分布的样本x（可以是训练集以外的样本），都能预知其所属的类。

The classification problem is then to find a good predictor for the class y of any sample of the same distribution (not necessarily from the training set) given only an observation [6]:338.

因此，同源染色体后代细胞对不同分布并不相同。

Hence, the homologous chromosomes distributed to different progeny cells are not identical.

Similarly, if we were to look at the radial probability distributions, what we would find is that there's an identical nodal structure.

相似地如果我们看看,径向概率分布,我们会发现有一个完全相同的波节结构。
