Python 2.7 sklearn.svm 警告信息
Python 2.7 sklearn.svm warning message
我 运行 Python 中的支持向量回归使用:
model=SVR(C=1.0, epsilon=0.01,kernel='linear',verbose=True)
我收到以下警告:
[LibSVM].........................................
Warning: using -h 0 may be faster
这是什么意思?我如何使用这些信息?
根据this post:
This means, that optimization algorithm detected that with high probability (not in the strict, mathematical sense) you can speed up your training by turning the -h 0 flag in your options. Basically, -h is the shrinking heuristics, implemented in the libsvm package which for some data significantly reduces number of required computations, while in others - makes it slower.
此标志在 sklearn 中使用 'shrinking' 参数实现,您可以将其设置为 False
(shrinking=False)
