Love, Loss, and Lennon
(In memory of John Lennon--poet, songwriter, singer, music man, and humane
activist--whose life was taken at age 40; John Lennon would have been 70
years old today, on his birthday: Saturday, October 9, 2010)
Nothing lasts forever;
No great deed can stand.
All sweet streams shall sever,
And, seeking, sink in sand.

以前好多sitcom都很好的，现在不行了
NBC's thursday lineup还不错，偶喜欢30 rock
two and a half men也还可以，角色搭配的不错
新出的ugly betty还可以，偶觉得betty不错，整个剧有点假
分类总结到此结束，以下是胡扯，当然以上也是
the sopranos偶觉得是拍的最好的电视剧，cast不知道怎么找的，形象都很符合, 也都
不大好看，演的却都很好，应该是ensemble里最强的一个，表演很自然，叙事非常流畅
，很多镜头拍的有电影的味道，总之拍的水平远超出一般电视剧。虽然讲的是黑社会，
其实都是普通人，偶最喜欢Tony's talk with Dr. Mefli. 不过最近两季没有以前好，
不知道最后怎么收尾。
weeds最近才看，看了之后就对Mary Louise Parker从四个housewife手上抢过golden
globe没意见了，剧组不大，拍的却很吸引人，是讲suburn housewife dealing
marijuana, 从剧情上讲有点DH+sopranos的味道，最大亮点是MLP的表演，小儿 |

另外，继决定视频codec后
HD DVD的音频codec也在9.22被批准
Confirmation of selection of following Audio Codecs for HD DVD video:
DD+ Lossy (mandatory), DTS++ Lossy (mandatory), MLP 2-Channel Lossles
s (mandatory), DTS++ Lossless (optional)
现在AOD和BD的关键之争就在于批量生产的cost和yield
BD的25GB只能达到70％和4 sec
AOD的30GB早已经90％和3 sec了
有兴趣的可以看看这个连接
这是BD和AOD在MEDIA-TECH Conference 上面的直接交锋
从BD的pdf的presentation中，看得出火药味到非常浓

发帖数: 337 | 5 首先上市的肯定是25GB的blue ray
SL的，采用的码流如果是H.264或者VC-1的话，基本是16Mbps
等效于MPEG2的25M以上bps
音轨估计是DTS＋＋ lossy，和MLP lossless
后者不肯定
时间反正是明年X-mas前后了
正式白皮书，估计明年上半年出来
AOD虽然输了，总算感谢它大大加快了这件美好事情的进程
要不是AOD，advance codec都不一定会进入Blue ray的规格书中 |

发帖数: 337 | 6 benQ年底之前要出的BD rom好像MSRP才600刀左右
BD的音频规格目前最新的版本是：
It now includes all the audio codecs for Blu-ray which are PCM, Dolby
Digital, Dolby Digital Plus, Dolby Lossless (formerly MLP), DTS, and
DTS-HD. The audio codecs are listed on page 17 of the document with sp
ecific audio parameters on page 18. The maximum bit rate for each audi
o codec is as follows: PCM is 27.648 Mbps, Dolby Digital is 640 Kbps,
Dolby Digital Plus is 4.736 Mbps, Dolby Lossless is 18.64 Mbps, DTS 1.
524 Mbps, and DTS-HD 24.5 Mbps |

nonlinear regression用最一般的MLP ANN就可以了，matlab里面什么都有的
svm通常用来搞搞分类 |

发帖数: 8812 | 22 今天有空瞎扯几句，版上的大神们不要见笑。其实今天很多人所谓的ML入门，其实是DL
入门，或者叫神经网络入门。我觉得可以分三步。
第一，把Goodfellow等著的deep learning书Part I and Park II都看懂，包括第一章数
学基础都查漏补缺完成，基本的理论基础就具备了。看不懂的youtube，Coursera，
udacity找资源帮助理解。
第二，自己实现几个简单的神经网络，我个人建议是用numpy手撕一个MLP，一个
vanilla的CNN和一个vanilla的RNN，重点是了解matrix(或者叫tensor)在层之间怎么流
动，forward（比如convolution），backward（尤其是RNN的backpropagation
through time）怎么实现。这些都不难，但是需要一些耐心。虽然耗时间，但是对彻底
摸清神经网络的工作细节很有帮助。所有的三个网络都可以用mnist数据集。
第三，学习一两个主流的libraries。个人推荐先学pytorch，后学tensorflow。因为这
两个是DL libraries的两种风格，imperat... 阅读全帖 |

发帖数: 182 | 23 取决于你想用什么类型的网络，如果是CNN的话，那就输入矩阵做卷积。如果你做
entity name resolution, 一般取一个sliding window取context，然后用一个普通的
MLP做训练，那么一个扁平的单向量就可以了。 |

发帖数: 136 | 24 我觉得二楼说的挺to the point的。
我自己刚考过不久，也有些经验跟你分享。
考完后发现考前VERY有必要看一下SFAS outlines, 从1到100多条，wiley book 书后有
(不知becher 如何）， 就十几页吧， 能发现很多重点。比如goodwill不能amortize，
应该。。。; 什么 cost 是expense or capitalize, such as R&D exp.
计算折现的也很多，但简单不过花些时间。lease 中算MLP也用它.
Pension expense 知道什么加什么减， 以及如何在报表中反映（这一点同样适用于其
他topics, 重要）。
Gov /Non gov AC 什么应含在 gov-wide statements 之类。 多数是些基础概念性的，
我碰到的并不算太多。
总之，考的比较基础。
另外，一定要控制时间。
Simulation 没啥好特别准备的。别忘了每个概念最基本的要求。
Writing只要层次清楚， 我只做了一个, 还有一个空白， 报告显示我这部分还

because market is becoming more and more efficient, lately its increasingly

business and being an employee. Everything regulated by contract (at PM
level) so neither side has any real possibility of complicating things -
comp and when you're out the door, risk levels etc predefined. They take
care of getting assets and backoffice, the PM everything else. If you want
an IT guy you hire one, if you want to use software X you buy it, if you
