I see you used Airflow for generic approach, but Argo has easier integration with MLFlow

So you have to retrain the model for each new user?

@JohnSmith-op7ls 4 ай бұрын

You can train a model to simply correlate various demographic attributes to liking certain things, then it can guess based on new user demographics. You can get more elaborate and first try to find if there are strong correlations between cohorts of certain baskets of demographics, then use that, alone or in combination with individual demographic attributes. Basically you have to run the numbers to see what produces the best recommendations. You wouldn’t have nearly enough data on new users to be statistically relevant in a data set large enough to itself be statistically relevant. Over time you’d want to,retrain the model as enough new data on new and existing users is added. Otherwise the model’s accuracy can drift.

Not necessarily--the model can still make guesses based on the behaviors of other users along with whatever data you feed it during inference. However updating the model with a user's past behaviors will increase accuracy. Hope that helps!
