Chromium 有 "Federated Learning of Cohorts" (FLoC) 吗?

Does Chromium have "Federated Learning of Cohorts" (FLoC)?

Google 已介绍 FLoC:

Federated Learning of Cohorts (FLoC) proposes a new way for businesses to reach people with relevant content and ads by clustering large groups of people with similar interests. This approach effectively hides individuals “in the crowd” and uses on-device processing to keep a person’s web history private on the browser.

这已经发布给客户,according to this website:

Google has launched trials of FLoC in Chrome browser version 89 on March 30th, 2021 in the USA, Canada, Australia, Brazil, Japan and several other countries for millions of users. FLoC is a part of the Chrome browser’s source code and it helps them do cookie-less and consent-less ad targeting.

通过阅读 FLoC,很明显它是 Google Chrome 浏览器 的一部分,但我不知道它是否也是 Chromium,底层开源浏览器项目?

这不是要启动 FLoC war 或讨论该技术的优缺点,我只是想了解它在技术堆栈中的确切位置,以了解我可能在何时何地遇到它.

我也在想这个,没有找到直接的东西。 以下是这个问题的可能答案:

您可以在此处找到 Chromium 中的 FLoC 代码:source.chromium.org/search?q=floc

要在 Chromium 中试用 FLoC,请下载 Chromium...chromium.org/getting-involved/download-chromium

...然后 运行 根据 floc.glitch.me.
