Artificial intelligence (AI) recommendation systems collect and analyze large amounts of data. These data can come from multiple sources such as purchase histories, website browsing behavior, product reviews, among others. Through data mining techniques and natural language processing (NLP), AI extracts important features and hidden patterns in this data that can predict user preferences.
These systems use machine learning algorithms to make predictions. These algorithms can be collaborative filtering-based, content-based, or a combination of both. Collaborative filtering algorithms make recommendations based on the choices and behavior of similar users, while content-based algorithms recommend items similar to those the user has interacted with or preferred previously.
These recommendation systems often employ deep learning techniques, such as neural networks, to improve the accuracy of their predictions. Neural networks can handle very large and complex datasets and can detect subtle patterns that other algorithms may overlook. This means they can provide more personalized and accurate recommendations.
