GALA: Generative Aligned Learning for Adaptive Multimodal Representation in the Taobao Shangou Recommender System

GALA is a three-stage pipeline extending existing learning frameworks, whose core innovation lies in an intermediate “generative RL alignment” stage that constructs multimodal pretraining data from user behavior and refines it via conversion-based rewards, effectively bridging the pretraining-fine-tuning gap to align w...
