When we need medical care, we expect decisions about our treatment to be made by our doctors, not a tech company's algorithm. But in January, the federal government launched a program that uses AI to evaluate Medicare beneficiaries' requests for certain procedures. EFF sued for records on WISeR, seeking badly needed transparency about Medicare's AI experiment. In our latest EFFector newsletter , we're talking about what happens when the government outsources treatment approval to private AI companies —without sufficient transparency, testing, or legal limits.

Reducing experiment duration with predicted control variates

I n 2021, we published a blog post titled “ Increasing experimentation accuracy and speed by using control variates ,” describing how we reduce the variance of metrics using CUPED in our experimentation platform. This is a follow-up on how CUPED has evolved at Etsy since then. Spoiler – It’s changed a lot, decreasing our average experiment duration by 3 days! Etsy’s mission is to Keep Commerce Human. To achieve this, we need to understand the impact each change to our platform has on our buyers' and sellers' experience. Whether that involves changing the color of the “Buy Now” button on the Et
