More specifically, page load time was 2.7 seconds without adblocker, decreased to 2.1 with uBlock Origin, but increased by 250% to 6.6 seconds with AdFlush, or increased to 3.4 seconds with AdFlush retaining prior predictions.

The superior score was an F1 of 0.86 vs 0.84 for AdFlush vs uBlock Origin, and it's not clear to me that this is a statistically significant difference. They do not claim it is.

That seems to argue for a first pass with a blocklist to filter out the well-known ad providers, and then possibly a followup step with the ML to catch things that are trying harder to slip by? But the extensions would have to cooperate to make that possible.

Thanks for extracting the details. It doesn't seem like they'll be competitive with blocklist-based approaches like uBlock Origin, because their features are fundamentally expensive to compute - parsing JS and such, not just matching URLs against a list of regexes.

Seems like it could work in the background to build up new rules for uBlockOrigin to deploy
