The complexity story is WILD: Standard attention: O(L²d) – quadratic scaling with sequence length
Grassmann mixing: O(Ld²) – LINEAR scaling (for fixed rank r) This isn't just theoretical. As sequences get longer, the gap becomes exponential.

Grassmann flows replace attention with geometric evolution
By
–
The alternative is mathematically beautiful: Grassmann flows replace attention with controlled geometric evolution on a manifold. – Reduce hidden states to r=32 dimensions (from d=256)
– Encode token pairs as 2D subspaces on Gr(2,r)
– Use Plücker coordinates to create geometric -

Massive attention matrices cause Transformer interpretability crisis
By
–
Here's the interpretability crisis no one talks about: Every Transformer layer creates an L×L attention matrix. Across 96 layers and 96 heads in GPT-4, that's a MASSIVE evolving tensor cloud. The paper proves this is why we can't interpret these models not their size, but their

Transformer performance matched without computing attention weights
By
–
This paper just murdered the foundation of every AI model you've ever used. A researcher proved you can match Transformer performance WITHOUT computing a single attention weight. Here's what changed (and why this matters now):

Derf: Replacing Transformer Normalization with Simpler Function
By
–
What if you could replace a core part of a Transformer with something simpler and stronger? Researchers from Princeton, NYU, and CMU present Derf. They swapped the standard "normalization" layer with a simple, element-by-element function called Derf (based on a Gaussian error

Iterative Improvements and Error Correction in Neural Networks
By

It's a neural network. Every minor update fixed errors and got smoother. Do you want to admit to what errors they fixed? I wouldn't. "We retrained the system so it doesn't run red lights in a small community in Idaho."
