Idea
A unified generative model for personalized search and recommendation improving retrieval and ranking for digital platforms.
Research Paper
Core Innovation
This paper introduces SynerGen, a single generative Transformer model that jointly optimizes retrieval and ranking for both personalized search and recommendation. It uses a hybrid pointwise-pairwise loss and InfoNCE for better semantic signal sharing across tasks. Additionally, it proposes a novel time-aware rotary positional embedding to incorporate temporal information effectively.
