Encoded but Not Actionable: Auditing the Decode-Generate-Steer Gap in Frozen LLMs for Geometric Constraints
TL;DR
This research audits the performance of frozen large language models (LLMs) in decoding geometric constraints, revealing a gap between what is encoded and what can be generated. Key findings indicate that while local geometric relations are decodable, the ability to generate actionable outputs from this information is limited.
✦ Why It Matters
Evaluate your LLM's ability to generate actionable outputs from encoded information in your applications today.
Key Takeaways
- Assess the pretraining impact on your LLM's decoding capabilities.
- Investigate the expressibility of encoded information in your models.
- Consider the limitations of LLMs in generating actionable outputs.
- Utilize controlled testbeds for evaluating model performance.
How It Works
The study probes hidden states of LLMs to evaluate their ability to decode geometric relations and generate outputs. By using parametric CAD constraints, researchers can isolate local pairwise relations from broader sketch-level constraints, allowing for a detailed analysis of model behavior.
