无意看到一个大神写的《Linear equations solver in 3 lines (Python recipe)》,Python解一元一次方程只需要三行就完成了,确实很强悍啊。 我们来围观一下: 说到底呢,这个段代码的关键是利用了复数。 第一步: 2 * x + 233 = x * 8 + 3 变成 2 * x + 233 -(x * 8 + 3) 然后把x变成虚数1j 然...
注意,若选择"l1"正则化,参数solver仅能够使用求解方式”liblinear"和"saga“,若使用“l2”正则化,参数solver中所有的求解方式都可以使用。 C:C正则化强度的倒数,必须是一个大于0的浮点数,不填写默认1.0,即默认正则项与损失函数的比值是1:1。C越小,损失函数会越小,模型对损失函数的惩罚越重,正则化的效力越强,...
