b******g 发帖数: 3616 | 24 兄弟,你joke大了吧。我以为你经常口出“500px是个joke”是研究过pulse算法呢。
你看到的49.9/50是当前的pulse,你点开每张照片把鼠标放在那个score上面就可以看
到他的历史最高pulse。而那个pulse才是真正有意义的数字。因为任何照片,即使曾经
到过99.9第一页第一张的照片,最终都会回到49/50。
本来打算之后写一篇500px算法解释的,你这么气急败坏的,我就稍微解释下。500px的
pulse只对你上传的24小时有效。24小时内能到多少分就意味着你照片的popular程度。
24小时一过,你的照片将会被系统自动扣分,而且扣的很多,我记得99.5+的照片第一
次扣完就直接掉到8X去了。一旦被扣分,你的照片就会掉到list很底下,也不会有多少
人关注了。也就是说24小时一过,这张照片的生命就基本结束了,很难再有点击率,之
后经过时间推移被一点点扣分,最后被回到4X-50分。
所以麻烦你点击下Editor Choice每张照片上的pulse,看看有多少张highest pulse低
于90分的。

b*******g 发帖数: 1309 | 25 先回答TOF的问题,你的理解不是很正确。
应该是放慢QTOF scan 速度 (就是增加 duty cycle 时间)增加灵敏度,但是跟
resolution无关。
一个pulse的时间,比如5ns的pulse跟50us的flight time 都是不能改变,或者很难改
变。必须加高pulse的电压才能缩短飞行时间(或者把flight tube该短)。缩短飞
行时间才能增加pulse frequency。
能改变的就是每个cycle里面pulse的数量, 如果做100个pulse是5ms (100X0.05ms)
加上digitizting 时间(假设10ms, 我还没查到具体数据,在2ms到几十之间),这样
一个cycle是15ms
如果增加到400个pulse,一个cycle就是30ms.
每个cycle产生一张谱图,每个谱图是所有pulse信号的叠加。100个pulse的信号只有
400 个pulse的1/4. 如果pulse数继续增多,dwell time(简单看就是digitizing时间
)不会减少,但是占的比例就越来越少,说所以信号损失越来越少。
所以说放慢QTOF sc... 阅读全帖 |

上传过20来张照片,从90出头一直到99.9的都有。所以对一张照片的分数是如何上升的
过程有了些理解。本来是想写的,后来觉得版上对这个题材有兴趣的人也不多,就不吃
力不讨好了。既然你有兴趣,简单说几句吧。
500px给自己的排名打分算法起名为pulse,这个名字真是再贴切不过。pulse算法的核
心有三个:
I 分数:由照片被like的绝对数量以及like/view的比例而决定的。
II 三层筛选:也就是500px discover那个页面中的fresh, upcoming以及popular
III 时间:上传24小时以后,任何照片的分数被大量削减。换句话说,一张照片“冲榜
”的时间只有24小时。
筛选的本质是一个简单的论坛心理学,既对于大部分时间有限的观者来说,只会关注任

则越没人看,也就不会有人再like/fav。简单说下这三层筛选。这其中定义的pulse时

50ms?
一个pulse的时间宽度是ns, 从离子被push开始到达detector 需要的飞行时间是0.05
ms level,
等飞行完了, 下一个pulse就可以又开始了,中间的不要等待。所以plus的频率是20k
Hz
另外如果检测范围增加,比如从0-1700Da 变成0-3200Da,所需的飞行时间变长,Plus
的频率必须降低。所以pulse的频率跟检测范围有关。
另外你的问题就变成了,为什么不把 pluse 时间宽度从ns变成us,这样灵敏度会增加
,但是TOF的resolution就变的很低。飞行时间质谱高分辨率是基于高精度的时间分辨
率。
另外一个spectrum是几百个pulse累加,不是一个pulse,所有pulse的数据会暂时存在
机器上,等完成了,digitize后传给电脑,这个时间大致需要几个甚至几十个ms (具
体我要查一下)。
增加每个spectrum里pulse的次数是增加灵敏度的有效方法,比如说一个spectrum从100

pulse的时间当然需要很短,不然resolution就没了.pulse和飞行时间一样长就不叫
pulse了...如果飞行时间和pulse OFF 时间都是50 us,pulse时间是5 ns,意味着99.
99%时间里通过的离子都没有进入reflectron,跟QqQ比只有1/10000
当然Tof resolution是Q的10000倍
要增加Tof的sensitivity当然只能加快扫描速度降低dwell time来提高pulse ON 时间
占的比重(比如从5 ns/500us 到 5ns/50us),因为单个pulse的时间不可能改变(这个对
于一个仪器应该是固定的), 这是你说的Tof加快扫描速度提高灵敏度的原因,当然同时
也损失resolution.
这应该是为什么没人用QTof做SRM的痕量检测的原因
我更想知道的是 QOrbitrap 的ON和OFF时间的比例.如果我的理解正确,c-trap收集离

Flickr从来没公开过interestingness的算法,网上讨论很多,但从来没见过明确结论

interestingness系统只是用来给照片排序,并不与照片的展示直接相关(基本上也只
有follow的人和share的group成员能看到);但500px的upcoming和popular都是直接与

相对值意义很大。像我前面举的例子,突发访问/总访问数/总faves/总likes/总
