因为选了《人体结构与功能》这门课，我无聊时也会在图书馆翻翻最新医学相关杂志。
在一本叫“基因”（还是“遗传”？）的专业杂志上看到一篇文章。
是一篇以人体已退化器官来追溯人类分化发展的文章。
说男性目前还都有结构跟女性一样的乳腺组织，和没用了的子宫结构。
然后后面那句话汗死我了……
“如果用适当的方式刺激男性乳腺，也是可以分泌乳汁的。”
我在图书馆差点没死过去。
专业的医学观点都是要大量实验支撑的，那么——
那位科学家是怎么做这个实验的啊啊啊！
回来和学医的一个朋友（男）探讨好久，朋友同意男性乳腺绝大部分和女性一样，但是

不承认男性泌乳。

至于做的怎么样
好像出名的文章不多
我们上场论的时候，朱雪天，说他和witten的老爸共过事
不知道是什么学校
witten的老爸据说不希望他做物理
所以witten念大学时是文科，历史还是什么忘记了
后来好像是到了三十多岁，有想做物理了
就去找某人，忘记是谁了，反正是个大牛
不过据说那大牛也不是很容易想出那种
不象witten，据说是很nice的一个人
那人给了他本场论，让他看完了再来找他
结果过了一周（？），witten就回来了
那人以为他不干了
但是witten却是对书中内容对答如流
他作物理的风格比较喜欢公理化吧
而且比较相信数学中也有自然的意义，偶瞎说的
反正就是和很多坐物理的人的风格不同拉
有人喜欢从实验出发
有人喜欢从数学出发
据说weinberg是很欣赏witten的风格的
80年代初witten作了些引力之类的东东
比如gravitational anomalies(呵呵，最近正在看这个）
还有超对称也有涉猎拉
还有比如large n limit of su(n) field辣之类的

Most of AMD’s public presentations were at 4K resolution using two cards or

数据维度不大 最终可能在40-50左右 其中1/3可能是discrete value (a few binary)
我们的anomaly平均大概每天1%-2% 每小时可能spike时也就5% 所以多数signal是
normal的 在这种假设下 其实多数就是计算对比距离 continuous value可以考虑用高

没有可用的算法 这算是一个density based local outlier detection问题 |
