作者:
Highlights:
• A fast weighted CP decomposition model for context-aware recommendation.
• Unifying explicit and implicit feedback by assigning non-uniform weights.
• Reducing computation time by element-wise alternating least squares.
• A simple and effective multi-threaded computing scheme for above model.
