Overview
- New method that reduces computational cost of large language models (LLMs)
- Introduces adaptive layer-skipping that skips unnecessary layers during inference
- Works on pre-trained LLMs without changing their parameters
- Achieved 56% speedup on LLaMA 2 with less than 1% performance drop
- Separate skipping decisions for attention and feed-forward network (FFN) layers
- Uses lightweight trainable routers to determine which layers to skip
Plain English Explanation
Have you ever thought about how much energy and processing power large language models need? These AI systems have dozens of layers that process information, but not all layers are equally important for every task.
This paper introduces a clever approach called adaptive layer-...
