Diffusion In Diffusion: Reclaiming Global Coherence in Semi-Autoregressive Diffusion

CoRR
One of the most compelling features of global discrete diffusion language models is their global bidirectional contextual capability. However, existing block-based diffusion studies tend to introduce autoregressive priors, which, while offering benefits, can cause models to lose this global coherence at the macro level.

Efficient Diffusion Planning with Temporal Diffusion

Proceedings of the AAAI Conference on Artificial Intelligence
Diffusion planning is a promising method for learning high-performance policies from offline data. To avoid the impact of discrepancies between planning and reality on performance, previous works generate new plans at each time step. However, this incurs significant computational overhead and leads to lower decision frequencies, and frequent plan ...
