A Calibrated Test of Internal Action Maps: State Signals Without Global Affine Closure
TL;DR
A calibrated test of internal action maps reveals that hidden state signals can be decoded without a reusable action map. The study shows that while some configurations pass various operational gates, significant error rates persist, indicating limitations in the model's compositional capabilities.
✦ Why It Matters
Evaluate your AI model's action map capabilities to enhance decoding and compositional performance.
Key Takeaways
- Test your AI models for hidden state signal usability without action maps.
- Focus on reducing error rates in model configurations.
- Explore earlier model layers for improved one-step transition performance.
- Assess the distinct roles of state availability and causal use in your models.
Full Summary
The research investigates how hidden state signals in AI models can be utilized without relying on reusable action maps. By testing action maps fitted without a source, the study organizes results into an evidence lattice, validating geometric properties on a known affine S_5 carrier.
The findings indicate that while 23 out of 30 configurations successfully navigate one-step and composition gates, error rates remain high, with a mean held-entity error of 0.519 for the Qwen/Qwen3-4B model. Notably, earlier layers showed better performance in one-step transitions, but decoding capabilities were weak.
The results suggest that state availability and causal use are distinct, highlighting the complexity of model calibration and composition.
