What is session-based recommendation?
Updated May 16, 2026
Short answer
Session-based recommendation predicts next items based on current session behavior.
Deep explanation
Unlike long-term user profiling, session-based systems rely only on recent user actions within a session. Models like RNNs, GRUs, or Transformers capture sequential patterns to predict next clicks or purchases.
Real-world example
E-commerce recommending next product during browsing session.
