Remember to Forget: Gated Adaptive Positional Encoding
Researchers have developed Gated Adaptive Positional Encoding (GAPE), a novel method to improve the performance of large language models (LLMs) with extended context lengths. GAPE addresses issues that arise when sequences exceed training limits, which can cause positional encodings like RoPE to degrade model performance. By introducing a content-aware bias into attention logits, GAPE selectively contracts irrelevant context while preserving important distant tokens, leading to sharper attention and better long-context robustness.
