At the moment, we automatically pick up on time-of-day, and day-of-week variations. We don't currently look at time-of-month and seasonal variation by default. This is because most people using our service at the moment, are not trying

There are really two different problems you are mentioning there. Problem 1 is the typical recommendation-system/ML problem of 'cold start', where there isn't sufficient training data examples to produce good predictions

I'm one of the founders - happy to answer any questions. I believe this sort of bandit-meets-machine-learning approach is going to have a big impact on web optimisation.

Well, it depends. If you already know exactly the 'age-out' behaviour that you want to capture, then maybe the best thing to do is bolt that on after doing your statistical inference. This keeps the 'complicated' bit of

But, like, isn't that being a bit 'cargo cult' about the fact the experiment was randomised? If the control isn't otherwise similar enough to isolate the hypothesis that we actually want to test (e.g. 'art makes you

When I hear an argument about a simpler explanation, I tend to assume there's an appeal to Occam's razor; but I'm not sure that's useful here: What's the chances that they took so much care to obscure their identity

As you say, mixing isn't really a solution - it requires that you trust the mixer to not steal your coins, and that you trust the mixer to not keep records. Looking at the efforts to compromise TOR, I don't think you can assume t
