BASIS: Balanced Activation Sketching with Invariant Scalars for "Ghost Backpropagation"
★★★★★
significance 3/5
The paper introduces BASIS, a new backpropagation algorithm designed to reduce the memory-intensive nature of exact backpropagation. By using balanced activation sketching and invariant scalars, the method decouples activation memory from batch and sequence dimensions while maintaining gradient stability.
Why it matters
Decoupling activation memory from sequence dimensions offers a critical path toward training massive models on hardware-constrained edge devices.
