DiffusionBlocks: Block-wise Neural Network Training via Diffusion Interpretation
✦ Why It Matters
Engineers can implement DiffusionBlocks to reduce memory usage while training large-scale neural networks effectively.
Key Takeaways
- Explore block-wise training to reduce memory usage.
- Utilize score matching for independent block learning.
- Apply DiffusionBlocks to various transformer models.
- Leverage this framework for scalable generative tasks.
How It Works
DiffusionBlocks transforms the training of neural networks by interpreting residual connections as updates in a dynamical system. By modifying these updates to align with a denoising process, each block of the network can be trained independently.
This approach allows for the application of score matching objectives, which facilitate the learning of each block without the need for storing activations from other blocks, thus significantly reducing memory requirements.
