发帖数: 594 | 1 positional faithfulness theory is a theory within Optimality Theory that
states that phonological asymmetries arises from a single pattern of
constraint interaction in an Optimality Theoretic grammar (Prince &
Smolensky 1993, McCarthy & Prince 1993a,b), one in which positional
faithfulness constraints crucially dominate context-free faithfulness and
markedness constraints. The theory brings into Optimality Theory the notion

但是有各自的动机，所以某些时候即使等价还是不要混在一起
比如对于贝叶斯理论，对于先验分布的选取，在很多时候就可以等价成regularization
的一个term，比如大家熟知的高斯先验，等价于L2 norm的constraint。拉普拉斯分布
的先验，等价于L1 norm的constraint。由此引申出一个好问题，L0 norm的constraint
等价于什么先验分布？我想过很久，似乎没什么好结论。
machine learning本质上可以分为generative和discriminative两个方向，SVM属于
discriminative，而Bayesian视为gen服务的，不一样
至于feature，都知道这是最重要的，不管gen还是dis，没有好feature，后面都胡扯了
，所以这个是最难的问题。现在的研究还是初步 |

Since biofuels is a hot topic, many researchers new to this field are eager

发帖数: 944 | 10 I want to minimize the energy E=f(p;...). p is a vector containing a set of
parameters.
I set initial values of each element in p based on some prior knowledge.
Then I use fmincon to find the optimal p that minimizes E.
Some elements in p are constrained in a range so I set the constraints
according to the syntax of fmincon.
The result is, the elements in p without constraints do not change (the same
as initial values), the elements that are initially in their constraints do
not change either, o |

I tried and it only ran 2 iterations before it was terminated. The 'max

first-order optimality are both 0. Is this normal?
What does max constraint mean? should it be close to 0 at the final
iteration? I used inequality constraint, something like Ax

How did you specify your constraints? Do you have a .sdc file or you set the
constraints through Quartus GUI?
You need to constrain every signal. Otherwise, the tool will do whatever it
wants to do. You need to properly constrain signals which are really
critical. For signals where timing doesn't matter, just specify a very loose
constraint.

Image that there is some logic first, then a register(FlipFlop), then the
output pad. 3.644 is the delay of the logic in front. Then the delay in the
FF (from d to q you know) is 0.099. Then 10.461 is the time from the
register output to the output pad. All other numbers are just the breakdown
of the three numbers. 3.644 is not the clock tree delay. All these are

叶行昆
内容提要：春秋、战国之际为中国古代社会的一个极为重要的制度转型期，诸子百
家均为未来社会新的制度安排纷纷提出了各自的理论体系；其中荀子创设的“礼制”思
想可谓不同凡响，“从经济思想上看，荀况不仅集了儒家的大成，而且也集了先秦各家
的大成。他是我国第一个从总体上对封建经济制度进行了理论分析的思想家。”荀子所
设计的“礼制”思想，为后来的大一统的封建帝国的经济制度与经济政策的制定，提供
了理论依据，其影响十分深远。笔者以为，荀子的“礼制”思想既是“荀学”的核心，
又是其经济思想的基石，更是具有中国传统特色的制度思想。
关键词：荀子、 “礼制”思想、 制度安排

Why do so many Chinese study physics and math relative to Americans?
The answer may be similar to why Germans, Swiss and Danes studied physics

That being, a long history of intellectual cultures in those other countries
and the lack of one here.

The Real Reason They Hate Trump
He’s the average American in exaggerated form—blunt, simple, willing to
fight, mistrustful of intellectuals.
Every big U.S. election is interesting, but the coming midterms are
fascinating for a reason most commentators forget to mention: The Democrats
have no issues. The economy is booming and America’s international position
is strong. In foreign affairs, th... 阅读全帖 |

Quick, What's the Fastest-Selling Car in America?
Answer: the Toyota Prius C hybrid car, according to Edmunds.com’s analysis
of March sales and inventory numbers. The Prius C, the newest, smallest and
least expensive member of the Toyota Prius hybrid family, barely has time to
dirty its tires because the Prius C, which starts at $19,000, stays on the
dealership lot only about eight days until a buyer drives it a... 阅读全帖 |

发帖数: 421 | 43 I'm doing applied research.
I used some mathamtical tools to solve a practical problem with practical
constraints (other people solved similar problems but neglected some
important constraints).
Clearly, the mathematical tools are not my contribution. Then, my
contribution is modeling a practical problem and solving it. However, this
seems not sufficient. How should I highlight my research?
Moreover, if I want to show some technical depth of my research, is it good
to show the mathematical deriv... 阅读全帖 |

发帖数: 1658 | 44 IMHO, try to emphasize how you figure out those imprtant constraints, the
consequences people have encountered by negelcting those constraints, and
the contribution to industry/academia using your improved appraoch...
in your research, mathematical optimization is just a tool (there are tons
of different optim tools to use). you do not need to focus on the tool
itslef. Formulating an optimzation problem and finding a suitable tool to
solve it is already important in engineering field. |

Put Away The Bell Curve: Most Of Us Aren't 'Average'
May 3, 2012
For decades, teachers, managers and parents have assumed that the
performance of students and employees fits what's known as the bell curve —
in most activities, we expect a few people to be very good, a few people to
be very bad and most people to be average.
The bell curve powerfully shapes how we think of human performance: If lots

发帖数: 889 | 46 同意你说的观点的出发点，至于结论我觉得是多角度的
有些人把research当成一个工作，自然做应该做的事情。这些人paper productivity，
job security是goal，兴趣是constraint
有些人把research当成自己的热情与生命，自然要追随老张的典型。这些人research
interest是goal，job security是constraint
每个人都在中间，有些人靠左一点有些人靠右一点
个人观点是，既然都到美国来了，大环境相对而言还是支持搞点真研究的。既然都选
择了教职，还是要追求兴趣的。除非真的生存压力很大。要不然，以大部分faculty的
智商情商，干其他啥也不差，都能有稳定工作，说不定赚得多还没那么操心。有些情
况没得选了，那就更要追求兴趣了，否则光一个job security，或者教授的虚名，值
不值这么累这么多钱，还真是不好说

紧急动员：决战最高法院， 请投庄严一票
捍卫你孩子公平竞争入学名校的机会
（必须是绿卡或公民才可以投票，谢谢合作。）
历史性的时刻已经到来了：2/21/2012，美国最高法院决定审理用“族裔”的理由来提
高亚裔和白人高校入学门槛的做法是否违宪。您--关爱孩子未来的父母--现在就可以花
一分钟时间来帮助孩子增大孩子上他们理想大学的机会。请您立即投票赞成（FOR） 80
-20全美亚裔教育基金会的民调书，清楚明白地表明亚裔在这件案子上的立场。
http://admin.80-20nj.info/cgi/80/e?l=8/11e/f&w=no
资料显示，亚裔在美国要比其他族裔成绩优秀许多才能上同样的学校。要上同样的名校
，亚裔SAT要考1550分，白人1410分，而非裔只需要1100分*（英文和数学满分是1600）
。亚裔入学这么高的门槛使得许多亚裔的大学申请者非常害怕，有些干脆拒绝列出他们
是亚裔—其实学校一看名字还是能知道哪些孩子是亚裔。。。
下面几周内，我们需要征集到至少五万个签名，让结果写入Amicus Curiae (“法庭之
友”的文书)作为证... 阅读全帖 |

For big ones, they all have match policy. If you do not contribute to your
401K, then you do not get the match. This is not "extra bonus", they are
part of your salary calculated already in the business cost of the company.
If it is not because of the government, companies can just give the match
part to you and allow you to manage the money in whatever way you want. The
cost for the company is the same. Just to give you... 阅读全帖 |
