Artificial intelligence (AI) recommendation systems collect and analyze large amounts of data. This data can come from multiple sources, such as purchase histories, website browsing behaviors, product reviews, among others. Through data mining and natural language processing (NLP) techniques, 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 based on collaborative filtering, content-based filtering or a combination of both. Collaborative filtering algorithms make recommendations based on the choices and behaviors of similar users, while content-based algorithms recommend items similar to those with which the user has previously interacted or preferred.
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 might miss. This means they can provide more personalized and accurate recommendations.
