What is recorded here?
Used warm-started subspace iteration to build low-rank gradient approximations compatible with all-reduce, combining them with residual feedback and momentum for practical distributed training.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Inherits power iteration, low-rank compression and error feedback. One iteration is not guaranteed to equal the best SVD approximation for every gradient; warm-start quality and rank matter. Orthogonalization/compression add cost; vectors may remain uncompressed. Source-specific wall-clock gains are not universal network/hardware speedups or lossless gradients.
