This is so amusing to me. I imagine their team goes to great lengths to obtain training data, clean it up and feed it to their ML algorithm.
Yet the most critical input data - direct feedback from the user on the traits that shape their interests, is completely ignored/not collected.
- baddox 7y agoPresumably IG is optimizing for something different than what you as a user would be optimizing for. Possible candidates would be “engagement” or sad impressions or clicks. As a user you probably don’t care to maximize how many ads you see or even how much you use the app. You just want to see things that interest you. And of course there’s absolutely no reason why IG would optimize for that.
- nightski 7y agoYou may or may not be right. I don't use instagram because of this. But how could they possibly know how relevant the data is to even their model since they do not even collect that data in the first place?
- baddox 7y agoWell, as others have noted, apparently they do have some affordance for that. But in general, the argument "why don't they collect data X to see if it's relevant to their goals" could be applied to literally any possible data X. Of course intuition must be used to focus data collection efforts.
- Nextgrid 7y agoThis is one of the reasons why I would never use such an app. If a tool would rather guess what I want (and obviously get it completely wrong) rather than ask me then I consider the tool defective and stop wasting my time with it.
