随着用户获得成本的持续攀升，许多业内人士开始寻找新方法以提升用户获取效能，包
括用每参与成本模型替代CPI，以及采用分析工具等。但人们通常所说的数据显示63%下
载量来自检索渠道仍然是一个十分可靠的说法。这让应用商店优化（ASO）成了一个比
付费获取更炙手可热的方法。
在我看来，ASO正处于应用开发与应用营销之间的无人区，营销人员极力避开它——我
认为这可能是因为该领域的参数指标严重不足所致，而开发者则将其视为Rubik魔方，
他们总有一天会破解它，但它实太是太复杂了。不管怎么说，这又不是他们的事情。
对开发者和营销人员来说，其中最令人困惑的元素之一当属iTunes App Store和Google
Play这两大主流应用商店之间的区别。无论你是开发者还是营销人员，我都希望本文
有助于你分清这两家应用商店的差异，并且获得进入这两者的合法渠道。

绿卡申请信模板七: EB2 NIW I-140 petition letter sample

下面是一封申请EB2 NIW I-140的petition letter的范例。这是多年前公开发表在
MITBBS“落地生根”版上的一个帖子。现在重贴于此，供大家参考。
个人点评：EB2 NIW的申请是技术活，满足NIW的三个方面都必须论证到位，否则就通过
不了；而且论证过程中，有些关键词必须出现在移民官的视野里。这封petition
letter基本上达到了这几方面的要求。更难能可贵的是，这封petition letter的后面
，还列出了所有的exhibit，值得参考。

发帖数: 80 | 4 由于本人的case比较弱，所以现在是EB1A 跟NIW 一起准备着。已经差不多写好了EB1A
的petition letter，开始准备NIW。看了几篇模板，发现有些疑问。
1. NIW 不需要列表格，油灯图等吗？为什么我看到的模板都没有这些，只有Exhibit？
2. EB1A的petition条理比较清楚，比方说我要claim三项，就从1，2，3几方面阐述。
但是NIW怎么感觉条理比较混乱呀？
请有经验的前辈指点迷津，小女子不胜感激！

这是第11代卡罗拉，为了吸引更年轻的用户而非维持以往用户，继“Avalon”
及“RAV4”之后，丰田再次采用了个性强烈的外观设计。前脸以较扁的前大灯以及下部
带大开口的保险杠等为特点，并搭配大幅膨出的翼子板以及向后平缓下滑的C柱。
新款卡罗拉的外形尺寸为长4639×宽1776×高1455mm，与上代车型相比车长增
加99mm，车宽扩大16mm，但车高降低10mm。轴距为2700mm，比上代车型长100mm。由于
轴距更长，因此后座臀点后移了75mm，另外还通过减薄前座靠背，使后座乘坐空间变得
宽敞。

发帖数: 975 | 20 你的理解是不对的……（不好意思，这个真的不是和你抬扛）
你对optimal strategy的理解还是不对。optimal strategy只和SPR有关。用bill chen
的话表述，假设你的range 从flop开始就只有air 和nuts的话，max ev（注意这个不是
optimal）的打法是3 barrel，river把钱打光，每个barrel都接近pot size。在这个
max strategy的基础上，每个street 的optimal play是像我上面说的那样来控制air
nuts ratio。每个steet上剩下的air check-fold。（这个是non-exploitable的
optimal play，但是并不max EV。）
如果你想在这个max ev的strategy 条件下，在每个street max你的ev，那就要像你说
的，根据对手的风格，自己的风格，调整size，调整ratio。

optimal play的时候才等价。这也是为什么，对手越弱，op... 阅读全帖 |

发帖数: 1 | 45 我选组选了Modeling and Optimization组，是跟机器学习有关的组，组内很多phd。
作为一个master搞机器学习对以后帮助大吗，大家都说搞机器学习需要读phd更好？
主要是担心以后发展受限，不好跳槽的问题，就机器学习本身来讲我还是有兴趣的。
如果在这个组感觉不行的话我打算一年后换组或者跳槽，不知针对这方面有什么建议吗？
恳请有相关方向经验的前辈指导一下，谢谢～
