Product Recommendation System in Machine Learning


With recommender systems, machine learning systems have largely helped businesses identify new products and services offered. When viewers go to YouTube a video suggestion is presented to the viewer based on the information and historical data of the visitor. This is the core function of the recommender system. They are crucial parts of our digital world; they have features that help users to identify what they are looking for in the noisy digital space. For businesses, this means happy customers and more sales.

Generally, a recommender system gives users better experiences at the same time exposing them to more hidden and relevant inventory. It has become a household tool and big corporations are adopting its use. Companies like YouTube, Amazon and Facebook are among the big users of recommender systems.
