I would like to know if there is a way to maximise recommendations generated by Related products model without relying on content based.
The only way we would see how you can optimise Related products to generate more recommendation without content-based is by sending more click and conversion events. This approach is rather counterintuitive because the Related products is a hybrid model (content-based and collaborative) which means you would need to send more events to compensate on what the combination of the two models can produce. By adding content-based, you can also get recommendations for the products that don’t have enough events and even improve the recommendations for the ones that do.
The way the hybrid model works is by combining, for each product, the recommendations based on events with the recommendations based on the attributes you choose. Meaning some products will have a set of recommendations from only one model, whereas some will have a combination of the two.
