how to deal with fit partial option in products recommendations system of e-commerce to new data points

Thanks for opening an issue!

Please include as much detail as possible: what does your dataset look like, what hyperparameters you are using (and have you tried other ones?).

When including code snippets, make sure you use appropriate code formatting using backtics. Have a look at the markdown reference for details: https://guides.github.com/features/mastering-markdown/.

The issue only mentions the fit partial option, products, and new data points; it names no files, tests, or entry points. First clarify the dataset, hyperparameters, expected behavior, and whether this is a usage question or a requested change. Done should be defined as a reproducible workflow or an explicitly scoped implementation.
