websurfing and an online Chinese TV program for their parents. |

websurf: $300 should be good enough, thin and light.
If gaming/computing, $1000;
If video editing, $2000+; |

Goal: 1250, 30*3, no after-dinner snack, 10:30
Don't grab food when I feel hungry because it's working.
Breakfast: breads + boiled egg - 250
Lunch: 1 cup of rice + 1/2 cup of tofu + stir-fried veggies - 600
Dinner: 1/2 cup of rice + 1/4 piece of fish + 1/2 cup of green beans + some snack - 500
Total: 1350 (100 over the daily limit)
Exercise: stretched during websurfing time
Went to sleet at 12:00 am - too late. |

India unveils prototype of $35 computer, paving way for solar-powered
websurfing in villages
If the government can find a manufacturer, the Linux operating system-
based computer would be the latest in a string of "world's cheapest"
innovations to hit the market out of India, which is home to the 100,000
rupee ($2,127) compact Nano car, the 749 rupees ($16) water purifier and
the $2,000 open-heart surgery. |

好像服务器上不错，但用在台式机上可能就比不上。笔记本可能用不上了。

发帖数: 2740 | 14 I got this Dell inspiron 640m
1. no virus
2. no big fancy software(only for websurfing and typing paper and read pdf)
comparing with 2 years ago, i add another 2G ram, but it is still slower
than before.
I heard all the hardware is life-time warranty, so does that means the
hardware doesn't contribute to the performance's declining?
so that's only because I change XP to win7 and office03 to office 10? and
ie6 to ie9? |

标 题: 求助: about leave-one-out cross validation
发信站: BBS 未名空间站 (Thu Feb 21 10:34:05 2008)
I am using LOOCV to estimate the classification accuracy because of small
sample size.
There are 3 classes. The sample size of these classes are [ 10 12 15]. I
used LOOCV on 10+12+15=37 samples.
My question is will the unbalanced sample size affect the estimation of
classifcation accuracy. Do I need to change the prior possiblity in the
classifier?
谢谢大牛们指点 |
