Task-aware pruning boosts LLM out-of-distribution performance

Researchers have investigated task-aware layer pruning and its impact on model capabilities, particularly for out-of-distribution (OOD) data. Their findings indicate that while this pruning method offers no benefit for in-distribution data, it consistently enhances OOD accuracy. The study proposes a geometric explanation, suggesting that pruning identifies and removes layers that distort a task-adapted geometry, thereby realigning OOD inputs and improving performance across various model scales.
