你又错了。
Multi-terrain 最基本功能就是控制油门和刹车。crawl control 是对着两个控制程度
最高的例子,可以没有driver imput情况下保持车匀速。
被你认为是多么先进的不踩油门只控制方向盘,其实是multi terrain 的常规功能

来自主题: ChinaStock版 - 我有些funding发给大家
我有大妈的微信号,还有其他的bonus吗?
大家都不说,我来说个idea把。
1. 先采集数据
a)试着写个code, 从版面把数据export出来,按日期count一下unique id#.
b)从public domain 找上证指数。
c)把两个数据按日期merge 一下。
2. Quality control
1) 去或impute missing value
2) 去 outlier
3) 看看数据,根据下面分析要不要做 normal transformation
3. 考虑用 time series analysis 或者 functional data analysis 做分析 (数据
correlated!)
4. Power analysis 就不做了,sample 应该足够大了
没人写就把200wb 发给我吧。 做就不做了, 太麻烦了:)

Given an sorted array, choose the middle element m, then m is the root of a

the left sub-tree. Doing this recursively, we can find (u,v) in O(log(n)).
