加油加油。
1. 教课第一年是很辛苦,要准备材料啊啥的,慢慢就熟了。
2. 开会的确很爽,但是认识人,如果没有下文,就得不偿失了
3. 跟系头关系一定要好,他可以帮你挡很多事情,连小米帮你办事都特别卖力
4. 全靠运气和rp
5. 循循善诱。软硬皆施。
6. 夫妻当然不能分开。 夫妻问题比research 问题难多了。 没有逻辑可言。。

得到博士offer的本科生简历(挂网公开的,应该可以讨论把)在下面,先只请教下打动
发考题们给了博士offer的原因,别的不八卦:)哈哈
照说本科生得让发考题们认为极其有科研的潜质,才能打败无数硕士生,发考题们才
会直接给本科生offer直攻博士;
看这份简历,我的感觉是
1.本科成绩好,会读书
2.参加了很多国内老师的项目,参加了一些海外老师的暑期短期项目,有些学术锻炼和想
法,但无明显成果,可能人缘好,会来事;但不排除夸大自己作用的可能
3.得了一些奖学金,国内高校基本上成绩好加积极参加学校各项活动,对老师会来事,自
然就能得.
3.英语写的好
4.积极参加各种活动,精力充沛,勤奋,把自己的时间,安排的满满当当的,有废寝忘食的
倾向.
5.非常有计划性和目的性,经过几年奋斗,作为本科学生,已经达到面面聚到的无短板程
度.
作为本科生,这份简历无疑是优秀的;但是却无法直接得出极其有科研的潜质的结论;相
反无数硕士生申请攻博士,由于年龄大一些和工作经历,也许本科成绩绩点低一些,得的
奖学金项目少一些,但是有实践经验,多数还会有1-2篇海外(尽管可能级别和影响不高)

理解成函数逼近是对的
不过是一个笼统的理解
具体如何来做决定了不同的研究方向
统计现在还是Bayesian当家
ML是nonlinear learning和large-scale optimization比较主流

小弟是某二流学校,数学PHD,因为从小就喜欢数学,所以之前打算做学术工作。
导师已经跟我说可以准备毕业了,我前一阵就在找学术界工作,可是找了半天,找不到。
position很少,极少数position也不要我。
看见job版各位大牛,争相报offer,眼花缭乱。
我想了很久,决定还是找个CS工作。
我以前就喜欢cs,同时怕找不到学术界工作,所以也有一些cs的训练
算法导论前面十几章看了很多遍,对sorting search之类的基本概念各种变化很熟。
C加加基本语法很熟,一些trick的细节也很清楚,design pattern也会一些。
大概两万行的水平,不会multi threading。
C语言也比较熟悉,大概一万行的水平。
Matlab写过几千行代码。
Python会一些语法,现在都忘了。
machine learning data mining一些经典算法也会。做过一个project,用到logistic,
