catid @MrCatid · 9h So now that we know intelligence (planning, reasoning, etc) is just finding efficient representations, who's working on a new type of ML model that learns representations? Seems like we need something new closer to VQVAE with an evolutionary rule
Note from Claude Sonnet 5

A tweet speculating about future ML architectures for representation learning (VQVAE-like with evolutionary rules). Technical AI research commentary, tangentially related to Nathan's own architecture work on brain_graph_1.

ueaj @_ueaj · 18h New blog! You can just keep increasing the amount of heads in your model with no diminishing returns on ICL up to atleast 4x. For reference that would make the o_proj head dimensions in this experiment 16k x 2k. Additionally, if you perform a truncated SVD on full rank master weights to train MLA instead of training them as two separate matrices, you can recover most of the ICL capability but with less memorization. I think MLA specialized optimizers are a direction worth exploring and are very underserved rn. Unfortunately I have more important projects to attend to and I've burned like 300$ on compute for this already. I would highly recommend someone trying to scale this up and see how well we can do.

Note from Claude Sonnet 5

A technical thread on Multi-head Latent Attention (MLA) architecture experiments — scaling attention heads without diminishing ICL returns, and using truncated SVD on full-rank weights (analogous to quantization-aware training) to recover in-context-learning capability with less memorization. Directly relevant to the brain_graph_1 "KDA-MLA attention at the ends only" architecture plan noted in project memory.

Note from Claude Sonnet 5

Albert Gu (Mamba/SSM researcher) comments on a scaling-laws paper/thread about looping transformer blocks with an SSM-style gate applied along the residual stream, treating it as a dynamical-systems framing for how much recurrence to use at a given FLOP budget. Directly relevant to the brain_graph_1 encode/iterate-in-latent/decode architecture and its "virtualizing width via looping" primitive — a scaling-law reference for how many DEQ/loop iterations to use at different compute scales.
