Do we have science that demonstrates humans don't autoregressively emit words? (Genuinely curious / uninformed).
From the outset, its not obvious that auto-regression through the state space of action (i.e. what LLMs do when yeeting tokens) is the difference they have with humans. Though I can guess we can distinguish LLMs from other models like diffusion/HRM/TRM that explicitly refine their output rather than commit to a choice then run `continue;`.
- Turskarama 9mo agoHave you ever had a concept you wanted to express, known that there was a word for it, but struggled to remember what the word was? For human thought and speech to work that way it must be fundamentally different to what an LLM does. The concept, the "thought", is separated from the word.
- minimaltom 9mo agoAnalogies are all messy here, but I would compare the values of the residual stream to what you are describing as thought. We force this residual stream to project to the logprobs of all tokens, just as a human in the act of speaking a sentence is forced to produce words. But could this residual stream represent thoughts which don't map to words? Its plausible, we already have evidence that things like glitch-token representations trend towards the centroid of the high-dimensional latent space, and logprobs for tokens that represent wildly-branching trajectories in output space (i.e. "but" vs "exactly" for specific questions) represent a kind of cautious uncertainty.
