Researchers have explored task-aware layer pruning as a method to enhance model performance on specific tasks, particularly for out-of-distribution (OOD) data. Their investigation revealed that while this pruning technique offers no improvement for in-distribution data, it consistently boosts accuracy when faced with OOD inputs. The study proposes a geometric explanation, suggesting that OOD inputs distort a model's task-adapted geometry, and pruning these distorting layers helps realign OOD inputs, thereby improving performance across various model scales.
