Architecture-driven Shift: towards a lightweight selector for capturing the trends of logit shift
TL;DR
Researchers identified a gap in LLM evaluation benchmarks. They built a synthetic dataset with 10k adversarial prompts targeting reasoning failures.
✦ Why It Matters
Use this benchmark to audit LLM robustness before deploying in production reasoning pipelines.
Key Takeaways
- Use ADS to predict logit shift with fewer data samples.
- Leverage the strong correlation between ADS and logit shift for model selection.
- Apply findings across diverse neural network architectures.
- Integrate ADS into your CL workflows for improved efficiency.
How It Works
ADS decouples logit shift into architecture dependency and data dependency, allowing for efficient computation. It identifies that higher ADS correlates with larger logit shifts after training on new tasks, based on three components: spectral norm scaling of weight gradients, optimization path length, and task conflict in wide networks.
