FlowTime: Towards Continuous Generative Watch Time Prediction via Flow-based Personalized Priors
FlowTime introduces a novel 'Continuous Generative Regression' paradigm for watch time prediction in short-video recommender systems, addressing limitations of existing regression, ordinal, and discrete generative approaches. The method uses flow-based personalized priors within a one-step generative VAE to model multimodal user-item interaction patterns while reducing inference latency, demonstrating superior performance in both offline experiments and A/B testing.
