Researchers have developed DUET, a novel framework using dual transformer encoders to improve offsite conversion rate prediction in recommendation systems. This approach tailors specific transformer architectures to distinct user behavioral data streams: one for dense click signals and another for sparse, delayed conversion signals. The framework's complementary embeddings are then combined for downstream ranking, demonstrating up to a 0.38% reduction in normalized entropy and leading to consistent improvements in conversion prediction accuracy during A/B testing.
