     在练习机器学习时，可能会选择决定是使用L1范数还是L2范数进行正则化，还是作为损失函数等。 L1范数也称为最小绝对偏差（LAD），最小绝对误差（LAE）。它基本上是最小化目标值（Yi）和估计值（f（xi））之间的绝对...

     The chi squared distance d(x,y) is, as you already know, a distance between two histograms x=[x_1,..,x_n] and y=[y_1,...,y_n] having n bins both. Moreover, both histograms are normalized, i.e. their
