Breaking the Lock-in: Diversifying Text-to-Image Generation via Representation Modulation

Researchers present DAVE, a training-free method that enhances diversity in text-to-image generation by attenuating the DC (zero-frequency) component of intermediate Transformer features during early generation stages. The technique addresses the problem of identical outputs from the same prompt without requiring expensive sampling overhead or auxiliary optimization.

Initialization is Half the Battle: Generating Diverse Images from a Guidance Potential Posterior

Researchers have developed Diversity-inducing Initialization (DivIn), a method that addresses mode collapse in generative AI models by sampling initial noise from a guidance potential posterior rather than using standard Gaussian initialization. The technique uses Langevin dynamics to steer initial conditions toward diversity-rich regions while maintaining data validity, improving performance in both image and text-to-image generation tasks.
