I want to build a recommender system via multiclass classification ( i have 10 classes in the target variable which are products ). I have 5 or 6 features describing a person. I already built a model for a binary classification ( 2 outputs 0 and 1 using a supervised learning) and got around 80% accuracy on unseen data which is almost good enough for me to put it in production. However, i did the same steps for a 10-class target variable, got 60% ( not good enough ). I would like to know the must-do steps to get a highly accurate recommender system that can be used in production.



Note : I can provide further details on my features / target variable, but I'm mainly looking for general steps for this type of classification. Please signal me for more details in case you need it for clarification and i'll edit my post. Thanks
