Practical advises on recommendation systems in production

• jancsika 4y ago
  How about this-- give me a sticky toggle to switch to a dumb sorted list-- other channel content, alphabetical etc. That at least lets the user run the experiment on themselves to check if the recommendation algo makes them sad. The fact that the sentence above is based on a real thing Facebook did to its unwitting users speaks volumes about our shitty timeline.

    You want a “dumb sorted list” of every video on YouTube?
    • Nextgrid 4y ago
      A dumb sorted list matching some criteria set by the user, like search results?

      The better analogy on the YouTube side is the chronological subscribed channels feed: https://www.youtube.com/feed/subscriptions https://www.youtube.com/feed/subscriptions

  "Running a logistic regression might be too informed a baseline and can become a long drawn process." What does this mean? To me it implies logistic regression is already so good that its hard to see the difference between it and most recommender systems. In which case, unless you're operating at massive scale, you can just go with logistic regression

    Logistic regression is a really good method and takes time to get right. But it is indeed one of the most performant models in multiple companies
  • Irishsteve 4y ago
    Depending on the size of the company (Revenue), and where / how the recommender system sits within the customer experience; Logistic regression could be fine. An even better baseline if discovery isn't so important for a good CX is to go with most popular and or a vendor. Building these systems used to be about getting lots of different things to work together which eats up a lot of time, and capacity (Product, UX, Eng) and it may not get the appropriate return.

  Please correct the title. It's "advice", not "advises". Advise is a verb. It reads as if an organization called "Practical" is advising on something. Edit: advice, no need for plural as in advices

    Genuinely not snarking, but isn't it just 'advice'?
    • jrh206 4y ago
      Indeed, "advice" is a mass noun, so it has no plural form. It's just like "rice". One grain of rice -> one piece of advice Lots of rice -> Lots of advice https://www.britannica.com/dictionary/eb/qa/When-to-Use-Advice-and-Advise- https://www.britannica.com/dictionary/eb/qa/When-to-Use-Advi...

  Most recommendations use the assumption that the user's need is the same at every point in time. This is why it doesn't work most of the time. I think it's strange recommendation systems don't ask more about the context. The answer to 'How do you feel today' can result in a total different playlist. Or a python programmer who also likes snakes might want to set the context before a search (in DDG you can).

  Based on the advices and the feedbacks received about our datas and evidences, we added syntactic sugars to our codes, which is sure to make us more moneys. Thank you for your hard works. This is indeed excellent new.
