以前用IPHONE,当我使用WIFI的时候,只要把cellular data 关闭就可以只用WIFI,
因为我的cellular data 是限量的。最近才换的BLACKBERRY ,有WIFI,但是当我启动
WIFI的时候,不能单独启动,需要TURN ON 手机的DATA才行,我的DATA是每月200MB,
当我用WIFI的时候(同时打开DATA)是不是也要消耗我的DATA 啊?

发信站: BBS 未名空间站 (Wed Aug 28 20:11:24 2013, 美东)
最近对big data比较感兴趣。个人分析了一下,主要是编程型的应用方向Cloud
computation - 包括parallel computation, Hadoop 和研究型的应用方向Data Mining
and Machine Learning - 包括Pattern recognition, Prediction. 还有
一些数据处理过程比如data cleaning, data visualization.
现在好像很多企业都需要做Data Scientist的人,跟Hadoop作parallel computation,
.Net做Web service。想往这个方向发展,感觉做研究型的应用方向应该越做越吃香,
不容易被新技术淘汰。但不知道这个方向能走多久,以后的薪酬如何。本人菜鸟级,对

本人在研究trading system 和 strategy desgin, 自然最先遇到的问题就是要维护好
历史data, 从而可以以此为背景做backtesting 去找到统计上的交易edge。我的data
是tickdata,格式如下图所示,
最后两列是volume,没有用,可以去掉的。这样就包含日期,bid, ask, 三个data。
如图所示,这些data很密集,两个月40个交易日大概有500万行这样的data,我在c#的
程序如果从储存这些数据的csv里边直接读取并存到内存里的data structure里的话,
大概30秒左右。然后再对内存里的进行回测,大体的思路是这样的。现在的问题就是
csv肯定是不合理的储存方式:
方案1: mysql, mssql去储存数据,但我看一些trading的论坛一些技术人员说因为这
些database是relational,对tick这样的time series不是最佳的方案。

来自主题: Programming版 - 没有data store的model有什么用吗?
今天和一个同事抬杠了,
他目前的项目是做一个spring mvc支持的project,他做是front-end layer,后端有
search, statistics 各种service api;
这个spring mvc项目主要是receive user's request/request data from backend, 然
后处理data再presentation 到页面;
他今天问我怎么做model,因为spring mvc不和任何database联系,他说没法做model,
我的想法是model你想要present的data(因为从后端返回来的json比较复杂,需要过滤
),再以json的形式推到javascript/html presentation layer.
而且他还有一个想法我觉得有点crazy,他的mvc还要cache从后端反回来的json data,
因为structure 很complex,需要java 过滤挑出有用的data,但是需要等user request
才能把过滤的相应的data发送到前前端的javascript/html。 我觉得这个会影响

I have seen this kind of question many times.
Normally, if the data are collected/organized by some private firms and
person A has the access to this data, you need to co-author with the data
providers in order to get the data. Otherwise, the firms may question your
data sources.
If the data are collected personally and that person might be glad to share
the data with you FOR FREE, you are fine.

你要真学data science 不如学统计ms,学data science 一般就可以做data , 但是学统
计可以做data science , statistician, modeler , quant, 英语厉害还可以当
consultant , Boston consulting group, 麦肯锡,好的consulting 公司挺多的,钱
也哗哗的。统计版说学统计的得phd,但是感觉印度人,美国人统计本科,ms都混得很好
。或者说别的族裔的学统计的少很多。很多公司的analyst 都是非统计,data major 的
人在做,不过都是外国人。也有国内数学,统计本科出国后学了cs, master , phd 的
,后来在美国当了码工.


: 学data science除了做data还能做什么?

不然的话学个cs master 也不错.cs master 也有做data analyst, data science 的。

来自主题: DataSciences版 - data science如何进阶呢?
小弟我从生物信息phd想转到data science
自己做过的有NGS-genomics之类的研究
也做过基于clinical feature 用ML进行phenotype prediction的研究
熟悉linux/hpcc,R,尤其是python(Numpy, Scripy, Matplotlib, Pandas, Scikit-
learn)这一套
学习了bishop的PRML,当然也补课了multi calculus,和线性代数
也刷过一些kaggle
刷kaggle和自己的phenotype prediction的套路都是:
feature engineering, data cleaning, machine learning data training, test
prediction, data visulization
请问掌握这些我算是入门了吗?
如果入门了的话,如何进阶呢?
是继续加深我的machine learning/数学的基础知识,以及加强python coding能力 (
我的自学当然不能跟科班比)
还是继续学习新的东西,比如mapreduce,Hado... 阅读全帖
