Starting from scratch: Training a 30M Topological Transformer 6 months ago
it makes sense architecturally
they replace dot-product attention with topology-based scalar distances derived from a laplacian embedding - that effectively reduces attention scoring to a 1D energy comparison which can save memory and compute
that said, i’d treat the results with a grain of salt give there is no peer review, and benchmarks are only on 30M parameter model so far
