非常激动地宣告，Stanford 教授 Andrew Ng 的 Deep Learning 教程，于今日，2013年4月8日，全部翻译成中文。这是中国屌丝军团，从2月20日战役打响之日，经过 50 天的团结奋战，取得的全面彻底的胜利。
此次战役的巨大胜利，之所以令人激动，有三方面的原因。
1. 在 Stanford 网站这个规模不算大，但是行业影响可观的舞台上，彰显了中国屌丝们，旺盛的求战热情，迅猛顽强的战斗作风，训练有素的战术技能。
2. 在 50 天的奋战里，不仅让全球的观众们，见识了中国屌丝的单兵技能，而且更令人印象深刻的是，中国军团的出色的合作精神。他们积极奉献，不争名次高下，相互鼓励，不嫉妒不挖苦，不仅动作迅猛、干净利索地完成自己的任务，而且积极补位，协助团队成员的更快更好地完成任务。
3. 这是国际众包，这种新型项目合作的有益尝试。Andrew Ng 教授在钦佩中国军队的强大的战斗力的同时，正在与我们积极探讨下一步的合作，例如，创办一个 OpenDL 开源项目孵化平台。详情今后陆续爆料。

以下是先前写的博客，包括项目的发起，以及状态的跟踪。保留于此，权作纪念。
年前与朋友商议，准备写一系列文章，介绍机器学习的前沿进展。
在网上东翻翻西看看，看到 Stanford 教授 Andrew Ng 的网页，http://deeplearning.stanford.edu/wiki/index.php/UFLDL_Tutorial。
越看越喜欢。Andrew Ng 教授写的教程，深入浅出，要言不烦，不卖关子，不摆噱头，这是真心想让读者看得懂的做法。
与其重新造轮子，不如锦上添花，敬重、继承、并发扬光大别人的已有成果。干脆不原创了，先把 Andrew Ng 教授的文章，翻译成中文。今后肯定有需要补充的地方，届时再原创也不迟。
晚上 21:00 PM，在新浪微博上发帖，谈翻译 Andrew Ng 教程的事情，很多志愿者非常热情地报名参与。三个小时后，26 篇教程，基本被分配完毕。
志愿者的热情很让人感动，但是翻译质量如何保障，是个难题。而且 Andrew Ng 是 Stanford 教授，也是我的同学。他为人宽厚，但是对工作质量，一点也不通融。
我们中国机器学习界，要走向世界，起步不嫌小，但是步子得扎实。低质量，往往不是工作能力问题，而是工作作风问题。工作作风浮夸，是丢面子的。窝在家里丢丢面子，也就算了，但是无论如何，不能丢到美帝那里去，不能丢到硅谷 Stanford 去。
所以，初稿翻译出来后，要严把质量关，该返工的，该枪毙的，一定不能手软。
下面是一份清单，左栏是 Andrew Ng 的教程，右栏是初译者名单。初译者的名字，都是他们在新浪微博上的浪号。
不仅要有初译者，还得有审稿者。审稿者名单日后公布。
文章翻译好以后，没有工钱，只有感谢。
另外，我们将联系 Andrew Ng，问他是否可以把中译本，也放在 Stanford Deep Learning 的网页上。并且，是否愿意商议版权，让出版社出书。
以下翻译进展，持续更新中。。
