发帖数: 197 | 1 请问python sklearn nearest neighbor user defined metric具体语句该怎样写的？？
像是
nbrs = NearestNeighbors(n_neighbors=4,algorithm='auto',metric='pyfunc').fit(
B)
distances, indices = nbrs.kneighbors(B)
这样？但是这个会给我一个error
ValueError: Unknown Distance Metric: pyfunc
但是从sklearn的document上看这东西应该是支持自定义distance的阿？？

metrics是最好的，但是在某个sub category里面google metrics 只列出了20到30个排
名靠前的杂志，也没有说这个category里的总杂志数，难道我就把这个页面打出来当作
证据吗？
求解答 |

发帖数: 3948 | 6 比如我们在训练模型的需要给出一个 loss function 比如 softmax 之类的 还要制定
一个metric。
forward 算出 loss， 然后 back propagation 去update 参数， 就用loss 就够了吧？
metrics 只是用来看看效果的 对吗？ 这个值参与具体优化吗？metrics 除了看看结果
评价还有啥用处？

Brazil, the world’s biggest soybean exporter, may import as much as 1
million metric tons from its main rival in global sales in a twist of the
topsy-turvy trade row between the U.S. and China.
As American soybean shipments to China ease, they’re being discounted. At
the same time, rising demand for Brazilian beans has exports fetching a
premium, leaving reduced supplies for domestic processors. That means some

请教一个问题关于优化。如果我有多于一个variable来进行优化，什么method比较好呢

目的是primary是最优的，然后secondary也不要下降。
如果现成的工具比如说R里面有包就好了。多谢！ |

However a unit baseline is much too large for normal human usage.
For example, If a guy thinks his mullet is sexy, that would have to rate at
about 20 microtrumps on your proposed scale, right? So most human delusions

次），总时间接近5小时，75mile,还超过了metric Century (62mile) 13 mile.

这是几个星期来头一次骑车，状态不是特别好，还好还坚持下来了。
对了，我还有2个问题请问大家
1）中途2次大腿有很强的抽筋的感觉，请问如何消除
2）骑完后，butt较难受，尤其是bottom下numb感觉很强。 |

发帖数: 17771 | 34 I was resolving physcial site failover based on the availability of certain
applications. It's similar to what you are trying to resolve, right?
I happened to have F5 box next to the Internet Routers, so I put a script on
F5 box, and the script does the healthcheck and dynamically modify the BGP
stuff.
So in your situation, you can probably use the TCL script built-in in the
router to do the healthcheck and modify the OSPF config, say metrics? BTW,
you run OSPF with your SP?

好多了，2下就起来了。不过比起原来开的老佳美差远了，老佳美从来就是一下着火的。
