标 题: Data scientist / Machine Learning Engineer 相关面试题
关键字: data scientist,machine learning
发信站: BBS 未名空间站 (Sun Oct 19 17:31:36 2014, 美东)
去年我找工作的时候发现板上针对data scientist,machine learning engineer面试
题总结很少,所以尽量申请了很多公司面试相关职位,想看看行业里这个方向都在问什
么。有幸去过不少地方面试,现在把那些题目整理整理(全部来自Amazon, Microsoft,
Yelp, Pinterest,
Square, Google, Glassdoor, Groupon的电面和onsite),希望能帮助在找相关工作的
同学们。
题目写的简略,请大家见谅

如果是做学术,为了发paper,可以看看这本书的书的Bayesian风格。如果是真的想学
习machine learning的实用技术,还是看《Elements of Statistical Learning》,里
面的技术浅显易懂,而且更实用更全面一些。Bishop的书全是Bayesian的理论,“误导
”过不少中国学生,都觉得现在最前沿的machine learning全都是做Bayesian的。其实
现实的machine learning应用,从来没有一种应用是Bayesian方法一定比传统统计学习
更好。所以让学生花太多精力去研究Bayesian的推导,不如用这些时间去学一些更多方
面的技术和应用,或许更好。

没有足够多其他信息的情况下,machine learning更好。
理由:machine learning 机会更多,不只academia,还有很多的industry机会,这样
给自己留更宽的后路。
从academia角度出发,跟application(biomedical)更紧密一点,比较容易拿funding
,但是做ML的也能做的跟application很紧密,取决于你怎么做。

bioinformatics 新AP一般也是10万上下吧。 bioinformatics 特别是 high dimension
genomic data用到machine learning挺多的,但是如果你的结论对biologist来说不
make sense,那就不make sense,他们不买账,你就没辙。 话虽如此,
bioinformatics +machine learning +genomics,再弄个几篇好文章还是比较容易找
教职的。话虽如此要我还是觉得biostats的faculty日子过得滋润多得多了。

标 题: fresh cs master找工作的疑惑以及machine learning的应用问题,请指点一下!
发信站: BBS 未名空间站 (Sun Oct 25 15:35:24 2009, 美东)
可是做过的project基本就是machine learning在具体问题中的的一些application基本
都是matlab中做的,所有的啥svm阿NN阿不是matlab中自带的functions就是利用比如说
svm-light package之类的,再根据具体问题按照一定procedure找出好参数拉,找好
model阿串起来。
一般cs master准备面试如果像备考那样看数据结构和算法,加上一门c++或java,大概
就是这个样子吧。我觉得即使这些我准备的很好还是有几大硬伤:
1.project没有正经用java或c++做过
2.作的东西也都是把现成的算法试来试去来解决问题,没有什么自己的创新。感觉我做
的东西挺弱的:code没啥技术含量,好像也从未涉及过什么高深的算法或那些很流行的

Actually, this is a special Map/Reduce scenario. All the machine can pass
its distribution (over each bucket) statistic (which is small compared to
the original data) to one machine and then it can be determined that which
bucket the median is in.

来自主题: JobHunting版 - machine learning的Phd都研究啥啊?
最近看了下machine learning,感觉很多idea挺有意思,虽然也不是很新。感觉搞
machine learning研究的,主要都用概率统计,比如Beyesian information 和EE那些
搞信息论,detection and estimation的用的东西很像。
classifer一定程度上,也可以理解成多元检测。
还有EE里搞compressed sensing,在ML里也看到搞dimension reduction用到。
neural network里的back propagation还有点像EE里coding的,都用message passing。
当然了,convex optimization在EE的信号处理和ML里都用到不少。
搞ML是不是很多东西可以借鉴EE里现成的啊?ML里最前沿的研究都是做什么啊?听说
data scientist也不怎么像马工那样写code。
EE(通信理论方向的)转ML,当data scientist是不是也比较自然啊?

下面是个人背景:
教育: 本科和phd都是非EE/CS的工科,现在是phd最后一年,本科有统计的minor, 博
士期间也修了不少统计的课,统计基础还算扎实。本科和博士的学校牌子都还可以。
研究: 博士期间做bioinformatics的,主要做disease classification and
clustering, 对各种machine learning的模型都有涉猎,但都学的不是很深。
编程:主要是matlab,用C++刷了leetcode一遍,SQL, R,Python都会一点。
最理想的职位是entry level的data scientist,可以把积累的一些machine learning
和统计的知识用在工作中,去tech公司,药厂都行。但感觉这行门槛高,很难进。纯SDE
我也愿意申请,一直没断了做题,状态应该也还可以。
感觉没有科班学位,也没有工作经验,第一份工作很难找呀,如果哪位大侠肯帮忙,我
会好好复习,认真面试,争取不给您丢人。我很勤奋,学习东西也挺快的,工作态度认
真负责,应该会是个好员... 阅读全帖

artificial intelligence is the superset of machine learning, data mining,

data mining is data-oriented, data-driven, and the solution could be ad hoc.
machine learning is hypothesis driven, and the solution must be able to
