How false_labels_per_helper generated in MaskLARK?

[duanbing]

Hi, guys, when reading https://github.com/WICG/privacy-preserving-ads/blob/main/MaskedLARK.md#step-2-browser-waiting-and-processing, I am confused by false_labels_per_helper, how does the browser produce this parameter?

Hi duanbing, sorry for the delay (somehow my notifications for this repo weren't on).

This is intended as a per-browser / per-user option, that is, the browser can set the number of fake labels they feel is reasonable. In practice choosing a couple random labels per real label, with some constraints, should be adequate.
