这个可以不用除

除不影响结果,但是公式里面是有的吧

是啊

这里为啥要用append,不太理解

这里为啥要用append,不太理解
ret = np.append(ret, np.sqrt(0.5 * regularization * np.square(p)))
通过回调、开方的操做,将正则化项当成数据项,从而可以调用,scipy.optimize.leastsq
from lihang-code.
这里为啥要用append,不太理解
可以看leastsq库里提供的参数的介绍:
f : callable
The model function, f(x, ...). It must take the independent
variable as the first argument and the parameters to fit as
separate remaining arguments.
the parameters to fit as separate remaining arguments,将用来调整的参数的数据(这里指的是正则项),作为其他参数传入
