Generative AI Meets RecSys: A Deep Dive into the Diffusion Recommender Model (DiffRec)

Ref from Diffusion Recommender Model Recommender systems are the invisible engines powering the modern digital economy. From the videos you watch to the products you buy, underlying algorithms are constantly predicting your next move. Historically, the evolution of these systems has followed a clear trajectory: from simple Matrix Factorization techniques to deep learning-based architectures, and recently, to Graph Neural Networks (GNNs) that capture high-order collaborative signals. However, a new frontier has emerged.
