PKO (隆 贝多芬) 于 (Mon Oct 10 09:07:27 2005) 提到:
有的前级有balance和unbalance两种接口，有的只有一种，但是balance的机型要比
unbalance贵，这是什么意思的说？

yfei (one flew over...) 于 (Mon Oct 10 11:06:27 2005) 提到:
balanced就是XLR口，unbalanced一般就是RCA。
balanced可以消除进入信号线的外部干扰，适合做长距离的。像演唱会的话筒除了无线的
都是XLR的。 http://en.wikipedia.org/wiki/XLR
如果CD和攻放就2米远，unbalanced应该够用了。 但是这种情况下还是有人说balanced
声音更好。
我的balanced+unbalanced双接口攻放就要到了，到时候我比较一下。

发帖数: 163 | 2 周末请问一个logistic regression 问题
Y 是 binary variable， 但是 unbalance， Y/N=1:8 左右 sample size=45000
我想请教大家都是如何处理unbalance data， 特别是在logistic regression里面
我想用bagging，搜了些文章，感觉有用的信息不多
bagging多数用在decision tree等unstable的model上吧，不知道在logistic 里面是否
会显著提升accuracy？
谢谢大家了 |

客车在行驶中突然越过中心实线，撞击对向正常行驶的小轿车后冲上路沿，撞断护栏坠
入江中。根据调查访问、调取公交客车沿线监控视频，初步确认当时公交客车上共有驾

几个小时内，却遭遇事实大反转。起初的新闻说是女司机逆行撞上大巴，女司机已被控

是公交车突然越过双实线撞上正常行驶的女司机驾驶的红色轿车；然后撞坏桥栏杆坠入
长江。原来女司机也是受害者。
女司机到底是肇事者还是受害者？重庆的公交车上到底有多少人？一事间舆情纷纷，真

发帖数: 14958 | 11 我不是专家，但我知道结论。 具体的给你看维基
Suppressors can increase the precision of a rifle, as they strip away hot
gases from around the projectile in a uniform fashion. The suppressor can
reduce the recoil significantly as it traps the escaping gas. This gas mass
is a little less than one-half the projectile mass (approximately 1.6 grams
vs 4 grams for 5.56x45mm NATO ammunition), with the gas exiting the muzzle
at about twice the projectile's velocity, thus giving a reduction in the
felt recoil of approximately ... 阅读全帖 |

可是好像 line-out 出来的应该是 stereo sound， 并且mixer 的 line in 有 L （

seems to me, 1D promising 4+ only possible when you open 1 major only promise
4 cards.
11-13 bal. if you open a 14-16 1NT. (Open 1C show a 17+ balanced hand or 16+
unbalance hand. this can solve the "16HCP vs 8HCP" problem of traditional 1C
open).
exchange these meanings, a jump reverse to 2NT promise good suit maximium and
0-2 cards in responder's major, a jump rebid promise good suit maximium and 3
card support in responder's major. This way seems more sensible.
