这一场在哪里,发生了什么?

周四上午 10 点,西雅图一家做仓储机器人的公司,线上视频复盘会

上周新上线的视觉检测模型出了问题:误检率明显上涨,仓库那边投诉机器人老是因为“看错”停下来。你是这个模型的负责工程师。今天的视频复盘会上,着急的产品经理 Rachel 和爱追问数据的数据团队负责人 Vikram 都在等你解释。

和谁对话?

Rachel
美国口音。产品经理,被仓库投诉压着,语气着急,想今天就回滚
Vikram
印度口音。数据团队负责人,冷静,爱追问数据细节

你要做到什么?

先说结论(误检率从 2% 涨到 9%,主要在 3 号仓夜班);讲清原因(新 LED 灯反光,训练数据里没有这种光照);说清影响(一周多停机约 140 次,无安全事故);顶住“今天就回滚”的追问,提出今晚调阈值的短期方案;回应漏检的担心,说出补数据、重新训练、两周上线的长期计划。

这一场轮到你开口 5 次:

  1. 先说结论
  2. 讲原因
  3. 说影响
  4. 顶住回滚
  5. 长期方案

全文:这一场怎么说?

中英对照,不用注册。每一句都能点「听」,录音就是 App 里这一场的录音,只有角色的台词。轮到你的地方,写着你想说的意思、三种说法和值得记住的说法:能说清是短句,先保证对方听懂;自然是同事平时会说的;高密度更紧凑、信息更多。

Rachel

Hi, everyone, thanks for jumping on. I'll be honest, the warehouse team is really unhappy. Their robots keep stopping for no reason.

大家好,谢谢上线。说实话,仓库那边很不满意,他们的机器人老是无缘无故停下来。

听懂:jumping on 上线(进会) · keep stopping for no reason 老是无缘无故停下

Vikram

Morning. I've pulled the stop logs from all sites, but I'd like to hear the model side first.

早。我把各个站点的停机日志都拉出来了,不过想先听听模型这边怎么说。

听懂:pulled the stop logs 调出了停机日志 · the model side 模型这边(的情况)

Rachel

Sure. You own the vision model. Give us the short version. What's going on?

好。视觉模型是你负责的。简单说一下,到底怎么回事?

听懂:you own the vision model 视觉模型归你负责 · the short version 简短版本

轮到你:先说结论

一句话给结论:误检率从 2% 涨到 9%,主要在 3 号仓夜班。

你想说的意思:先说结论:新模型上线后,误检率从 2% 涨到了 9%,大部分出在 3 号仓的夜班。

  • 能说清
    Bottom line: false positives went from 2% to 9%. Most are from Warehouse 3, on the night shift.
  • 自然
    Bottom line: since the new model went live, false positives jumped from 2% to 9%, and most are from Warehouse 3's night shift.
  • 高密度
    Bottom line first: since the new model went live, false positives have jumped from 2% to 9%, and about 80% are coming from Warehouse 3's night shift.
值得记住的说法中文
Bottom line first先说结论汇报开头用,让人马上抓住重点
since the new model went live自从新模型上线以来go live=上线
jumped from … to …从……猛涨到……比 increased 更口语、更有画面感
are coming from …出在……、来自……说问题集中在哪里
Vikram

Hm, okay. But the model passed all our tests. So what's different out there?

嗯,好。可是模型所有测试都过了,那现场到底有什么不一样?

听懂:passed all our tests 通过了所有测试 · out there 在现场

轮到你:讲原因

说清原因:3 号仓上个月换了 LED 灯,反光很强,训练数据里几乎没有这种光照。

你想说的意思:根本原因是灯光。3 号仓上个月换了新的 LED 灯,反光很强,我们的训练数据里几乎没有这种光照的图片。

  • 能说清
    Warehouse 3 got new LED lights last month. They cause strong reflections. Our training data has almost no images like that.
  • 自然
    Warehouse 3 switched to new LED lights last month, and they cause strong reflections. Our training data barely covers that kind of lighting.
  • 高密度
    The root cause is lighting. Warehouse 3 switched to new LED lights last month, and the glare is strong. Our training data barely covers that kind of lighting.
值得记住的说法中文
The root cause is …根本原因是……复盘会上说原因的标准开头
switched to …换成了……
barely covers …几乎没覆盖到……比 has almost no 更地道
that kind of lighting那种光照
Rachel

Okay, that makes sense. But I need real numbers for the warehouse managers. How bad has it been? Was anyone hurt?

好,这说得通。不过我得给仓库经理们实际数字。情况有多严重?有人受伤吗?

听懂:that makes sense 说得通 · How bad has it been? 情况有多严重

轮到你:说影响

说清影响:一周多机器人多停机约 140 次,没有安全事故。

你想说的意思:这一周多来,机器人多停了大约 140 次。好消息是,没有发生任何安全事故。

  • 能说清
    In about one week, the robots had about 140 extra stops. There were no safety incidents.
  • 自然
    Over the past week or so, we've had about 140 extra stops. The good news is there were no safety incidents.
  • 高密度
    Over the past week or so, we're looking at roughly 140 extra stops. The good news is, no safety incidents at all.
值得记住的说法中文
Over the past week or so过去一周多or so=左右,口语常用
extra stops多出来的停机
The good news is好消息是先报坏消息再给好消息,让人安心
no safety incidents没有安全事故
Rachel

Okay, I'll pass that on. But they keep asking me one thing. Can we just roll back to the old model today?

好,我会转告他们。不过他们一直问我一件事:能不能今天就回滚到旧模型?

听懂:pass that on 转告 · roll back to the old model 回滚到旧模型

轮到你:顶住回滚

不同意整体回滚,提出短期办法:今晚把 3 号仓的阈值从 0.5 调到 0.65,误检预计降到 4% 左右。

你想说的意思:我觉得没必要整体回滚。今晚我可以把 3 号仓的检测阈值从 0.5 调到 0.65,误检应该能降到 4% 左右。

  • 能说清
    I don't think we need a full rollback. Tonight I can change the threshold for Warehouse 3. I want to raise it from 0.5 to 0.65. That should bring false positives down to about 4%.
  • 自然
    I'd rather not do a full rollback. Tonight I can raise the threshold for Warehouse 3 from 0.5 to 0.65. That should bring false positives down to around 4%.
  • 高密度
    I'd rather not roll back the whole thing. A quicker fix is to raise the threshold for Warehouse 3 from 0.5 to 0.65 tonight. That should bring false positives down to around 4%.
值得记住的说法中文
I'd rather not …我不太想……比 No 客气,表达不同意但不硬顶
A quicker fix is to …更快的办法是……拒绝之后马上给替代方案
raise the threshold调高阈值
bring … down to …把……降到……
Vikram

Hold on. If the model gets less sensitive, couldn't the robot miss a real obstacle? And what's the long-term fix?

等一下。如果模型没那么敏感了,机器人会不会漏掉真正的障碍物?还有,长期怎么解决?

听懂:less sensitive 没那么敏感 · miss a real obstacle 漏掉真正的障碍物(漏检) · long-term fix 长期解决办法

轮到你:长期方案

承认漏检可能略升、会密切观察;再说长期方案:补拍 5000 张新灯光下的图片,重新训练加测试,两周内上线。

你想说的意思:有道理。漏检可能会稍微上升,我们会盯紧。长期来说,我们补拍 5000 张新灯光下的图片,重新训练、测试,两周内上线。

  • 能说清
    Yes, misses may go up a little. We will watch them closely. Long term, we will collect 5,000 new images and retrain. It takes about two weeks.
  • 自然
    Fair point. Misses may go up a little, so we'll keep a close eye on them. Long term, we'll collect 5,000 images under the new lights and retrain, within two weeks.
  • 高密度
    Fair point. Misses may tick up slightly, so we'll keep a close eye on them. Long term, we'll collect 5,000 images under the new lights, retrain, test, and ship within two weeks.
值得记住的说法中文
Fair point.有道理先认可对方的担心,再回答
keep a close eye on …密切关注……比 watch 更地道
under the new lights在新灯光下
within two weeks两周之内
Rachel

Okay. I can work with that, as long as we watch it closely. Vikram, can your team help on the data side?

好。只要盯紧,这个方案我能接受。Vikram,你们组能在数据这块帮忙吗?

听懂:I can work with that 这个我能接受 · as long as 只要 · on the data side 在数据这块

Vikram

Yes, I'll put two people on it. And let's review the stop numbers together every morning this week.

可以,我派两个人上。另外这周每天早上我们一起过一下停机数据。

听懂:put two people on it 派两个人来做 · review the stop numbers 看一遍停机数据

Rachel

Great. I'll update the warehouse team after this call. Thanks. That was really clear.

太好了。会后我去跟仓库那边同步。谢谢你,讲得很清楚。

听懂:update the warehouse team 跟仓库团队同步情况 · after this call 这个会之后

没听清、卡住时怎么接?

这一场准备的救场的话:没听清、一时想不起词,先用一句接住,再想内容。

英文中文
Sorry, you cut out for a second. Could you say that again?抱歉,刚才断了一下,能再说一遍吗
Let me share my screen.我来共享一下屏幕
Good question. Let me check and follow up after the call.好问题,我查一下会后回复
Just to make sure I understand, …我确认一下我理解得对不对……
