????Pinterest數(shù)據(jù)科學(xué)家安德莉亞?伯班克

????Pinterest是一家以圖片為主的社交網(wǎng)絡(luò)，數(shù)據(jù)科學(xué)家安德莉亞?伯班克主要負(fù)責(zé)該公司的A/B測(cè)試，評(píng)估公司網(wǎng)站、APP的外觀或功能變化會(huì)對(duì)它的6000萬(wàn)全球用戶產(chǎn)生哪些影響。如果Pinterest網(wǎng)站上的某個(gè)小模塊讓你想邀請(qǐng)朋友也來(lái)玩一玩，或是某一封它發(fā)來(lái)的推薦郵件讓你關(guān)注了更多話題，那么這很可能就是伯班克團(tuán)隊(duì)的那只“看不見(jiàn)的手”起了作用。她在今年三月的一次行業(yè)會(huì)議上表示：“為了今后能為幾十億用戶提供服務(wù)，我們已經(jīng)針對(duì)幾百萬(wàn)用戶做了數(shù)百次試驗(yàn)。”試驗(yàn)還拓展到了Pinterest自身的運(yùn)營(yíng)上。伯班克最大的成就之一，就是給Pinterest的其他員工賦權(quán)，讓他們也能開展試驗(yàn)。她表示：“以前只有一個(gè)故障點(diǎn)，但也只有一個(gè)知識(shí)點(diǎn)，現(xiàn)在不同了。”——Andrew Nusca

????Andrea Burbank, Data Scientist, Pinterest

????At the image-focused social network Pinterest, data scientist Andrea Burbank leads A/B testing, evaluating how changes in the look or functionality of its website, mobile application, or communications impact the behavior of its roughly 60 million users worldwide. When a small module convinces you to invite a friend to the service, or a recommendation email induces you to follow more boards, it’s likely that Burbank and her team have their invisible hands on it. “I’ve watched hundreds of experiments go by on millions of users for a combination of billions of user days,” she said at an industry event in March. The testing extends to the company’s own processes, too. One of Burbank’s big wins was democratizing the ability for other Pinterest employees to run experiments. “Before, there was a single point of failure, but also a single point of knowledge,” she said. Not anymore. —Andrew Nusca
