Task Context Shapes Component Roles in Language Models
TL;DR
Task context significantly influences how shared attention heads in large language models respond to different tasks, altering their outputs and interactions. This study reveals that task-dependent changes can enhance model performance by redistributing influence among components.
✦ Why It Matters
Consider analyzing task context in your models to optimize their performance on specific tasks.
Key Takeaways
- Investigate how task context affects model behavior.
- Utilize graph facts to understand component interactions.
- Apply targeted interventions to improve specific model outputs.
- Measure influence changes to guide model adjustments.
How It Works
The study employs a network view of language model computation, comparing fixed components across tasks using graph facts. By measuring how interventions affect attention heads and later activations, it reveals that task context alters both the graph facts processed and the influence on subsequent computations.
