What is sequence modeling in recommendation systems?

Updated May 16, 2026

Short answer

Sequence modeling captures order of user interactions to predict future behavior.

Deep explanation

Sequential recommendation models consider the order of interactions rather than treating them as independent events. Techniques include Markov chains, RNNs, and Transformers. They are effective for modeling evolving user preferences.

Real-world example
