Normalizing Trajectory Models achieve exact likelihood training with few steps

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Normalizing Trajectory Models (NTM), a novel approach to generative modeling that maintains exact likelihood training even with a reduced number of sampling steps. NTM integrates conditional normalizing flows within each step of the generative process, allowing for expressive modeling and end-to-end training. This method achieves competitive or superior performance on text-to-image benchmarks using only four sampling steps, a significant improvement in efficiency while preserving the integrity of the likelihood framework. AI

IMPACT Introduces a method for more efficient generative modeling with exact likelihood, potentially speeding up image generation and improving model training.

    Normalizing Trajectory Models

    Diffusion-based models decompose sampling into many small Gaussian denoising steps -- an assumption that breaks down when generation is compressed to a few coarse transitions. Existing few-step methods address this through distillation, consistency training, or adversarial object…
