What happened
Apple Machine Learning Research proposes a method to accelerate text-to-video generation by optimizing attention mechanisms in transformer models.
Why it matters
This could lead to more efficient and faster algorithms, which is important for real-time applications.
Recent diffusion models enable the generation of high-quality video but face the challenge of slow performance. The primary cause is the use of large transformer models, which are slowed down by computations related to spatiotemporal attention.
The research showed that a significant portion of connections between tokens in these models yields negligible results, and these patterns often repeat. This allows skipping some attention computations without substantially affecting the final outcome.
This observation also applies to connections between local blocks of tokens, opening the possibility for further optimization and acceleration of video generation.
