Diffusion-EXR: Controllable Review Generation for Explainable Recommendation via Diffusion Models

Researchers propose Diffusion-EXR, a new AI model that uses Denoising Diffusion Probabilistic Models (DDPM) to generate review text for explainable recommendation systems. The model corrupts review embeddings with Gaussian noise and learns to reconstruct them, achieving state-of-the-art performance on benchmark datasets for recommendation review generation.
