It dosen't matter which model were used or which algorithm, what matters is based on which information about this particular user it was decided what to show. If you only have his IP then ok, but if you have his browsing history then you should disclose that your targeting was based on exact browsing history or any other data you have concerning this user that was used.
- theoh 9y agoYeah, but if the entire history (some large part) is available, then it is in the interests of advertisers to run their algorithm against that. It's not informative. Needless to say, there is a lot of work being done in academia on the problem of making AI decisions comprehensible to humans. It is not clear yet AFAIK whether any ML techniques (even the most prominent approaches) are ever going to be susceptible to a simple explanation.
- nitrogen 9y agoCouldn't you just pick the top N paths (maybe ordered by how sensitive they are to changes in input) back through the neural net, then list the data sources they ultimately trace to? "Visited aaa.example one day ago, .34; visited abc.example three days ago, .27; therefore display ad for zzz.example"
- wolfgke 9y ago> Yeah, but if the entire history (some large part) is available, then it is in the interests of advertisers to run their algorithm against that. If they had to disclose what information was used to show the ad, this would at least give a small disincentive to do that.
